Gene Summary

Gene:ACHE; acetylcholinesterase (Cartwright blood group)
Aliases: YT, ACEE, ARACHE, N-ACHE
Location:7q22.1
Summary:Acetylcholinesterase hydrolyzes the neurotransmitter, acetylcholine at neuromuscular junctions and brain cholinergic synapses, and thus terminates signal transmission. It is also found on the red blood cell membranes, where it constitutes the Yt blood group antigen. Acetylcholinesterase exists in multiple molecular forms which possess similar catalytic properties, but differ in their oligomeric assembly and mode of cell attachment to the cell surface. It is encoded by the single ACHE gene, and the structural diversity in the gene products arises from alternative mRNA splicing, and post-translational associations of catalytic and structural subunits. The major form of acetylcholinesterase found in brain, muscle and other tissues is the hydrophilic species, which forms disulfide-linked oligomers with collagenous, or lipid-containing structural subunits. The other, alternatively spliced form, expressed primarily in the erythroid tissues, differs at the C-terminal end, and contains a cleavable hydrophobic peptide with a GPI-anchor site. It associates with the membranes through the phosphoinositide (PI) moieties added post-translationally. [provided by RefSeq, Jul 2008]

IGF-IEc Expression Is Associated With Advanced Differentiated Thyroid Cancer.
Anticancer Res. 2019; 39(6):2811-2819 [PubMed] Related Publications
BACKGROUND/AIM: Recent knowledge implicates a differential expression of the insulin-like growth factor-I (IGF-I) mRNA splice variants (i.e., IGF-IEa, IGF-IEb and IGF-IEc) in cancerous tissues, implying possible specific roles of the encoded IGF-I protein isoforms in cancer biology. In particular, there is growing evidence that the IGF-IEc isoform may play a distinct biological role in various types of cancers. The present study investigated whether IGF-IEc expression is associated with a particular type of thyroid cancer.
MATERIALS AND METHODS: Formalin-fixed paraffin-embedded tissue specimens of different types of thyroid cancers from 92 patients were assessed for IGF-IEc expression by immunohistochemistry. In addition, thyroid cancer biopsies of different TNM staging histological types were evaluated for mRNA expression of the IGF-IEc transcript by real-time polymerase chain reaction (PCR).
RESULTS: From the total number of 92 samples, 2 were anaplastic, 10 medullary, 4 hyperplasias of C-cells, 11 follicular, 5 hurtle cell carcinomas, 2 poorly differentiated, 5 nodular hyperplasias, 1 lymphoma and 52 were papillary thyroid cancers. The age of cancer diagnosis or tumor size did not significantly affect the IGF-IEc expression. Among all types of cancers, IGF-IEc was expressed in papillary differentiated thyroid cancer. Its expression/localization was mainly cytoplasmic and significantly associated with TNM staging and the presence of muscular and capsule cancerous invasion (p<0.05). Similarly, a differential profile was revealed regarding the mRNA expression of the IGF-IEc transcript, that exhibited a higher expression in aggressive compared to the non-aggressive papillary cancers.
CONCLUSION: IGF-IEc isoform expression in thyroid cancer is positively associated with more advanced stages of papillary thyroid cancer.

Intraocular medulloepithelioma - A review of clinical features, DICER 1 mutation, and management.
Indian J Ophthalmol. 2019; 67(6):755-762 [PubMed] Free Access to Full Article Related Publications
Intraocular medulloepithelioma is a nonhereditary neoplasm of childhood arising from primitive medullary epithelium. It most often involves the ciliary body. Most patients present between 2 and 10 years of age with loss of vision, pain, leucocoria, or conjunctival congestion. The mass appears as a grey-white ciliary body lesion with intratumoral cysts. Presence of a neoplastic cyclitic membrane with extension to retrolental region is characteristic. Secondary manifestations like cataract and neovascular glaucoma may be present in up to 50% and 60% patients, respectively. These could be the first signs for which, unfortunately, about 50% patients undergo surgery before recognition of the hidden tumor. Systemic correlation with pleuropulmonary blastoma (DICER1 gene) has been documented in 5% cases. Histopathology shows primitive neuroepithelial cells arranged as cords closely resembling the primitive retina. Histopathologically, the tumor is classified as teratoid (containing heteroplastic elements) and nonteratoid (containing medullary epithelial elements), each of which are further subclassified as benign or malignant. Retinoblastoma-like and sarcoma-like areas may be seen within the tissue. The treatment modality depends on tumor size and extent of invasion. For small localized tumors (≤3-4 clock hours), conservative treatments with cryotherapy, plaque radiotherapy, or partial lamellar sclerouvectomy (PLSU) have been used. Plaque brachytherapy is generally preferred for best tumor control. Advanced and extensive tumors require enucleation. Rare use of intra-arterial and intravitreal chemotherapy has been employed. Systemic prognosis is favorable, but those with extraocular extension and orbital involvement show risk for local recurrence and metastatic disease, which can lead to death.

Primary hepatic gastrointestinal stromal tumor with right adrenal gland invasion: A case report and systematic literature review.
Medicine (Baltimore). 2019; 98(20):e15482 [PubMed] Free Access to Full Article Related Publications
INTRODUCTION: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors that mainly occur in the gastrointestinal tract. The GISTs that are sporadically reported in extra-gastrointestinal regions are named as extra-gastrointestinal stromal tumors (EGISTs). However, the primary EGISTs that originate from the liver are rare.
PATIENT CONCERNS: A 64-year-old female presenting with right upper abdominal pain and thirsty for more than 20 days.
DIAGNOSIS: A diagnosis of a 15 × 14 × 7 cm liver mass located in the posterior right lobe of liver and spread to the right adrenal gland was confirmed. Pathological results showed that the tumor was mainly composed of epithelial cells and tested positive for CD117 and SDHB (succinate dehydrogenase complex iron sulfur subunit B). The gene mutational analyses for c-Kit and platelet-derived growth factor receptor alpha exons revealed negative results. Fluorescence in situ hybridization of murine double minute 2 produced negative fluorescence results which distinguished it from dedifferentiated liposarcomas. The postoperative gastroduodenal and colorectal endoscopy did not find any neoplastic lesions. To this end, the diagnosis of primary hepatic EGIST of wild type nature was confirmed.
INTERVENTIONS: The patient received right hepatectomy and adrenalectomy, no postoperative chemotherapy was administered.
OUTCOMES: The patient died 11 months after surgery due to tumor metastasis.
CONCLUSION: Primary hepatic EGIST is a rare and complicated disease of liver, a multidisciplinary team is necessary in diagnosis and treatment of primary hepatic EGIST.

Indolent T-cell lymphoproliferative disease with synchronous diffuse large B-cell lymphoma: A case report.
Medicine (Baltimore). 2019; 98(17):e15323 [PubMed] Related Publications
RATIONALE: Indolent T-cell lymphoproliferative disease (T-LPD) of gastrointestinal tract is a rare recently described disease that seldom progresses. We report a case of T-LPD with synchronous diffuse large B-cell lymphoma (DLBCL) that cause aggravation of disease.
PATIENT CONCERNS: A 46-year-old Chinese male presented with intermittent paraumbilical colic pain, bloating, and occasional diarrhea for 10 years. His condition aggravated with partial bowel obstruction recently. The patient was diagnosed as T-LPD initially based on histological result and T-cell receptor-gamma clonal gene rearrangement test. The patient was followed without chemotherapy. His condition stabilized for 1 year and then deteriorated with small intestine perforation.
DIAGNOSIS: The patient was diagnosed as indolent T-LPD and DLBCL finally.
INTERVENTIONS: The patient had surgery for intestine perforation and received chemotherapy for DLBCL and T-LPD afterward.
OUTCOMES: At 6 months follow-up, the patient continued to have resolution of his symptoms.
LESSONS: Early detection of high-grade transformation of T-LPD or the coexistence of aggressive lymphoma is essential for the patient. DLBCL may coexist in the indolent course of T-LPD. The diagnosis of T-LPD should be made cautiously in case with progressing symptoms such as intestinal obstruction.

Organochlorine and organophosphorous pesticides may induce colorectal cancer; A case-control study.
Ecotoxicol Environ Saf. 2019; 178:168-177 [PubMed] Related Publications
OBJECTIVES: Among the numerous agents, genetic factors and environmental elements such as pesticides have an important role in colorectal cancer (CRC) incidence. The present study aimed to investigate the probable-role of some organochlorine pesticides (OCPs) and organophosphorous pesticides (OPPs) in patients with CRC.
METHODS: In this case-control study, 42 patients with CRC and 30 healthy subjects were selected. The serum levels of some OCPs (α-HCH, β-HCH, γ-HCH, 2,4 DDE, 4,4 DDE, 2,4DDT and 4,4DDT) were measured by gas chromatography (GC) method. Serum levels of malondialdehyde (MDA), and total antioxidant capacity (TAC) as well as the enzyme activity of acetylcholinesterase (AChE) and arylesterase activity of Paraoxonase-1 (PON-1) were evaluated in all participants. The methylation specific PCR (MSP) assay was used for determining the methylation status of CpG island of p16 and MGMT genes in CRC patients.
RESULTS: The mean serum levels of each OCPs were significantly higher in the patient group compared to the control group (P < 0.001). The AChE and arylesterase activity of PON-1 in the patient group were significantly lower than the control group (P < 0.001). The mean serum levels of MDA and TAC in the serum of the patient group were significantly higher than the control group (P < 0.001 and P < 0.002, respectively). The current findings demonstrated significantly hypermethylation of p16 promoter in CRC patients.
CONCLUSION: Regarding the higher levels of OCPs in CRC patients, along with hypermethylation of the p16 promoter gene, diminishing in AChE and PON-1 activity and increasing in oxidative stress factors, the role of OCPs and OPPs in the CRC progression in the South-East of Iran may be assumed.

Effect of lncRNA HULC knockdown on rat secreting pituitary adenoma GH3 cells.
Braz J Med Biol Res. 2019; 52(4):e7728 [PubMed] Free Access to Full Article Related Publications
Pituitary adenoma is one of the most common tumors in the neuroendocrine system. This study investigated the effects of long non-coding RNAs (lncRNAs) highly up-regulated in liver cancer (HULC) on rat secreting pituitary adenoma GH3 cell viability, migration, invasion, apoptosis, and hormone secretion, as well as the underlying potential mechanisms. Cell transfection and qRT-PCR were used to change and measure the expression levels of HULC, miR-130b, and FOXM1. Cell viability, migration, invasion, and apoptosis were assessed using trypan blue staining assay, MTT assay, two-chamber transwell assay, Guava Nexin assay, and western blotting. The concentrations of prolactin (PRL) and growth hormone (GH) in culture supernatant of GH3 cells were assessed using ELISA. The targeting relationship between miR-130b and FOXM1 was verified using dual luciferase activity. Finally, the expression levels of key factors involved in PI3K/AKT/mTOR and JAK1/STAT3 pathways were evaluated using western blotting. We found that HULC was highly expressed in GH3 cells. Overexpression of HULC promoted GH3 cell viability, migration, invasion, PRL and GH secretion, as well as activated PI3K/AKT/mTOR and JAK1/STAT3 pathways. Knockdown of HULC had opposite effects and induced cell apoptosis. HULC negatively regulated the expression of miR-130b, and miR-130b participated in the effects of HULC on GH3 cells. FOXM1 was a target gene of miR-130b, which was involved in the regulation of GH3 cell viability, migration, invasion, and apoptosis, as well as PI3K/AKT/mTOR and JAK1/STAT3 pathways. In conclusion, HULC tumor-promoting roles in secreting pituitary adenoma might be via down-regulating miR-130b, up-regulating FOXM1, and activating PI3K/AKT/mTOR and JAK1/STAT3 pathways.

Bilateral mantle cell lymphoma of the ciliary body that responded to a combined local radiotherapy and chemotherapy regimen: a case report.
BMC Cancer. 2019; 19(1):355 [PubMed] Free Access to Full Article Related Publications
BACKGROUND: Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) that often affects men over the age of 60. Systemic metastasis of MCL to eyes is rare and intraocular involvement is even rarer, which usually affects the choroid and iris. To the best of our knowledge, ciliary body metastasis of systemic MCL has not been reported.
CASE PRESENTATION: A 59-year-old Han Chinese male with past-history of systemic MCL complained of redness, pain and blurred vision in the left eye. Ocular examination revealed a normal appearance in the right eye, and conjunctival injection, pseudohypopyon and anterior protrusion of peripheral iris in the left eye, all of which were unresponsive to corticosteroid treatments. Ultrasound biomicroscopy (UBM) and B-scan were then performed which detected ciliary body masses in both eyes with no vitreous and retino-choroidal anomalies. Combined liquid-based cytology tests and gene rearrangement assays of the aqueous humor specimen confirmed this to be a B-cell malignancy. Then both eyes were treated with external beam irradiation (40 Gy, delivered evenly in twenty fractions) over a course of one month. Additionally, the left eye received intravitreal methotrexate (MTX) (weekly for the first month, every two weeks for the second month, and monthly thereafter) over a course of twelve months. This therapy eventually led to complete remission of all symptoms in one month and disappearance of the ciliary body masses in twelve months.
CONCLUSION: Here we first reported a case of bilateral ciliary body MCL infiltration which was diagnosed by combined liguid-based cytology and gene rearrangement of aqueous humor cells. UBM may serve as a valuable tool in the diagnosis and serial assessments of anterior segment tumors.

Circulating miRNA Signature as a Potential Biomarker for the Prediction of Analgesic Efficacy of Hydromorphone.
Int J Mol Sci. 2019; 20(7) [PubMed] Free Access to Full Article Related Publications
No practical biomarkers currently exist for the prediction of the analgesic efficacy of opioids. Previously, we reported circulating miRNA signatures differentially regulated by µ-opioid receptor (MOR) agonists in healthy subjects. We hypothesized that these miRNAs could be potential pharmacodynamic biomarkers to estimate MOR stimulation, and predict the efficacy of opioids; i.e., patients with low MOR stimulation may be more vulnerable to strengthening of the MOR signal upon hydromorphone treatment. To test this hypothesis, plasma samples were obtained from 25 patients with cancer pain prior to the initiation of hydromorphone treatment and the circulating miRNA levels were evaluated, focusing on four miRNAs (i.e., hsa-miR-423-3p, hsa-let-7a-5p, hsa-miR-26a-5p, and hsa-let-7f-5p) and four miRNAs (i.e., hsa-miR-144-3p, hsa-miR-451a, hsa-miR-215, and hsa-miR-363-3p) that were most clearly up and downregulated by hydromorphone and oxycodone. The patients were classified into two classes with putative high and low MOR signal, estimated based on the plasma miRNA signature. A significant correlation was observed between the analgesic efficacy and the putative MOR signal level, and patients with low MOR signal achieved better pain control (i.e., ΔVAS < 0) through hydromorphone. These results suggested that plasma miRNA signatures could serve as clinical biomarkers for the prediction of the analgesic efficacy of hydromorphone.

Ginsenoside Rk1 Induces Apoptosis in Neuroblastoma Cells Through Loss of Mitochondrial Membrane Potential and Activation of Caspases.
Int J Mol Sci. 2019; 20(5) [PubMed] Free Access to Full Article Related Publications
Neuroblastoma (NB) is the most common childhood cancer, with a very poor prognosis. More than 60% of children with NB die within five years; therefore, a more effective therapy for NB is required. Although ginsenoside has been shown to significantly inhibit the growth of various cancers, the effect of ginsenoside Rk1 on neuroblastoma has not been known yet. Hence, we examined the anticancer effects of highly pure Rk1 on neuroblastoma cell lines. The apoptotic effects of Rk1 on neuroblastoma cells were examined using cell viability assay, flow cytometry and cell staining assay, and the change in gene expression levels were analysed using RT-PCR, western blots, and immunohistochemistry. The metastatic effect of Rk1 was monitored by wound healing assay, invasion and migration with Matrigels. Rk1 inhibited neuroblastoma cell viability dose-dependently. Rk1-induced apoptosis was investigated through nuclear condensation and mitochondrial membrane potential loss, and it showed that Rk1 can induce cell cycle arrest at the G0/G1 phase but also inhibit the metastatic ability of neuroblastoma cells. Moreover, Rk1 (30 mg/kg) injections markedly inhibited xenograft tumor growth. These findings demonstrate that Rk1 might be valuable in the development of anti-cancer agents for neuroblastoma treatment.

Subependymoma involving multiple spinal cord levels: A clinicopathological case series with chromosomal microarray analysis.
Neuropathology. 2019; 39(2):97-105 [PubMed] Related Publications
Subependymomas of the spinal cord are rare, do not often involve multiple levels, and very rarely recur. Here, we present a series of spinal cord subependymomas with a detailed description of the clinical, radiological and pathological features, and characterization by chromosomal microarray analysis. Briefly, the four patients included two men and two women, between the ages of 22 and 48 years. The most common presenting symptoms were neck and arm pain with upper extremity weakness. By imaging, the tumors were found to involve multiple spinal levels, including cervical/ cervico-thoracic (three patients) and thoracic (one patient), were all eccentric, and had minimal to no post-contrast enhancement. Two patients underwent gross total resection, one had a sub-total resection, and one underwent biopsy alone with a decompressive laminectomy. Follow up ranged from 6 months to 22 years. One patient (case 4) had recurrence 15 years following gross total resection and chromosomal microarray analysis revealed deletions on the long arm of chromosome 6. Our limited series suggests that spinal cord subependymomas can rarely recur, even following gross total resection, suggesting a possible role for long-term surveillance for these rare tumors.

Haploinsufficiency of the brain-derived neurotrophic factor gene is associated with reduced pain sensitivity.
Pain. 2019; 160(5):1070-1081 [PubMed] Free Access to Full Article Related Publications
Rare pain-insensitive individuals offer unique insights into how pain circuits function and have led to the development of new strategies for pain control. We investigated pain sensitivity in humans with WAGR (Wilms tumor, aniridia, genitourinary anomaly, and range of intellectual disabilities) syndrome, who have variably sized heterozygous deletion of the 11p13 region. The deletion region can be inclusive or exclusive of the brain-derived neurotrophic factor (BDNF) gene, a crucial trophic factor for nociceptive afferents. Nociceptive responses assessed by quantitative sensory testing demonstrated reduced pain sensitivity only in the WAGR subjects whose deletion boundaries included the BDNF gene. Corresponding behavioral assessments were made in heterozygous Bdnf knockout rats to examine the specific role of Bdnf. These analogous experiments revealed impairment of Aδ- and C-fiber-mediated heat nociception, determined by acute nociceptive thermal stimuli, and in aversive behaviors evoked when the rats were placed on a hot plate. Similar results were obtained for C-fiber-mediated cold responses and cold avoidance on a cold-plate device. Together, these results suggested a blunted responsiveness to aversive stimuli. Our parallel observations in humans and rats show that hemizygous deletion of the BDNF gene reduces pain sensitivity and establishes BDNF as a determinant of nociceptive sensitivity.

Cancer without Pharmacological Illusions and a Niche for Mycotherapy (Review).
Int J Med Mushrooms. 2019; 21(2):105-119 [PubMed] Related Publications
In this review we outline a framework in which mycotherapy is effective in the field of oncology. We suppose that irreversible epigenomic changes in cancer cells and achieving their replicative immortality when cancer-specific targets are absent should take away any illusions about a fundamental possibility of pharmacological blockage of the cancer process once ontogenesis begins. At the same time, however, we believe that effects of both traditional and alternative medicines on cancer clonogenic units within a particular range can lead to prolonged remission; with this in mind, we carefully consider the various possibilities of mycotherapy in controlling cancer activity. The aforementioned range is limited to nondisseminated cancer processes and depends on the absence of large secondary tumor nodes and the inexhaustibility of immune depots after chemotherapeutic treatment. The main therapeutic effect of fungal bioactive complexes is dectin-1-mediated immunity, including the reprogramming of dendritic cells, which significantly increases the period during which tumors generate immune tolerance. An inhibitory effect of fungal bioactive complexes on some molecular mediators of proliferative signaling and components of proinflammatory (synergistic with cancer) immunity can be considered less significant. The effect of fungal bioactive complexes on vital (including overexpressed) targets of cancer cells is even more limited. The results of this study stress that mycotherapy is only one of the tools that can be used to balance remission. Palliative mycotherapy is associated with polyphenols composites, which contribute to detoxification and to the suppression of inflammation and pain sensation.

Thrombospondin-4 expression as a prognostic marker in hepatocellular carcinoma.
Gene. 2019; 696:219-224 [PubMed] Related Publications
BACKGROUND AND AIMS: The extracellular calcium-binding protein family member thrombospondin-4 (THBS4) regulates cell migration, proliferation, attachment, adhesion, angiogenesis, neural development, tissue structure, organ development, pain signal transduction, and tumor growth. The aim of this study was to study THBS4 expression in hepatocellular carcinoma (HCC) and determine if it was a prognostic marker for this malignancy.
METHODS: We used immunohistochemistry and tissue microarrays to evaluate THBS4 expression in 84 HCC and matched para-cancerous tissues. Then, we assessed relationships between THBS4 expression and clinicopathological parameters.
RESULTS: THBS4 expression was higher in HCCs than in matched para-cancerous tissues (P < 0.001). There was a significant correlation between high THBS4 levels and preoperative serum alanine aminotransferase (P < 0.04). In HCC patients, high THBS4 expression was associated with shorter overall and disease-free survival compared with low THBS4 expression. Additionally, subgroup analysis showed that high THBS4 levels were only associated with poor overall survival for alpha-fetoprotein >40 ng/mL (P = 0.028) and cirrhosis (P = 0.002). Multivariate analysis showed that high THBS4 expression was an independent prognostic factor for both overall and disease-free survival.
CONCLUSIONS: Our data suggest that THBS4 may play a role in HCC development, and thus may be an independent prognostic marker and/or potential therapeutic target for HCC patients.

Correlation of P2RX7 gene rs1718125 polymorphism with postoperative fentanyl analgesia in patients with lung cancer.
Medicine (Baltimore). 2019; 98(7):e14445 [PubMed] Free Access to Full Article Related Publications
The aim of this study was to investigate the association between purinergic receptor P2X7 (P2RX7) gene rs1718125 polymorphism and analgesic effect of fentanyl after surgery among patients with lung cancer in a Chinese Han population.A total of 238 patients with lung cancer who received resection were enrolled in our study. The genotype distributions of P2RX7 rs1718125 polymorphism were detected by polymerase chain reaction and direct sequencing. Postoperative analgesia was performed by patient-controlled intravenous analgesia, and the consumption of fentanyl was recorded. The postoperative pain was measured by visual analog scale (VAS). Differences in postoperative VAS score and postoperative fentanyl consumption for analgesia in different genotype groups were analyzed by analysis of variance assay.The frequencies of GG, GA, and AA genotypes were 46.22%, 44.96%, and 8.82%, respectively. After surgery, the postoperative VAS score of GA group was significantly high in the period of analepsia after general anesthesia and at 6 hours after surgery (P = .041 and P = .030, respectively), while AA group exhibited obviously high in the period of analepsia after general anesthesia (P < .001), at postoperative 6 hours (P = .006) and 24 hours (P = .016). Moreover, the patients carrying GA and AA genotypes needed more fentanyl to control pain within 48 hours after surgery (P < .05 for all).P2RX7 gene rs1718125 polymorphism is significantly associated with postoperative pain and fentanyl consumption in patients with lung cancer.

TES functions as a Mena-dependent tumor suppressor in gastric cancer carcinogenesis and metastasis.
Cancer Commun (Lond). 2019; 39(1):3 [PubMed] Free Access to Full Article Related Publications
BACKGROUND: In our previous study, we identified a candidate tumor suppressor gene, testin LIM domain protein (TES), in primary gastric cancer (GC). TES contains three LIM domains, which are specific interacting regions for the cell adhesion and cytoskeleton regulatory proteins. Mena is a known cytoskeleton regulator that regulates the assembly of actin filaments and modulates cell adhesion and motility by interacting with Lamellipodin (Lpd). Therefore, we hypothesized that TES plays a role as tumor suppressor in GC through interacting with Mena. This study aimed to investigate the tumor suppressive functions of TES in GC.
METHODS: We explored the tumor suppressive effect of TES in GC by in vitro cell proliferation assay, colony formation assay, cell cycle analysis, Transwell assays, and in vivo tumorigenicity and metastasis assays. The interaction of TES and Mena was investigated through immunoprecipitation-based mass spectrometry. We also analyzed the expression of TES and Mena in 172 GC specimens using immunohistochemistry and investigated the clinicopathological and prognostic significance of TES and Mena in GC.
RESULTS: TES suppressed GC cell proliferation and colony formation, induced cell cycle arrest, and inhibited tumorigenicity in vitro. Additionally, it inhibited GC cell migration and invasion in vitro and suppressed metastasis in vivo. TES interacted with Mena, and inhibited the interaction of Mena with Lpd. Transwell assays suggested that TES suppressed migration and invasion of GC cells in a Mena-dependent fashion. In GC patients with high Mena expression, the expression of TES was associated with tumor infiltration (P = 0.005), lymph node metastasis (P = 0.003), TNM stage (P = 0.003), and prognosis (P = 0.010). However, no significant association was observed in GC patients with low Mena expression.
CONCLUSIONS: We believe that TES functions as a Mena-dependent tumor suppressor. TES represents a valuable prognostic marker and potential target for GC treatment.

Short-term gain, long-term pain: the senescence life cycle and cancer.
Genes Dev. 2019; 33(3-4):127-143 [PubMed] Free Access to Full Article Related Publications
Originally thought of as a stress response end point, the view of cellular senescence has since evolved into one encompassing a wide range of physiological and pathological functions, including both protumorignic and antitumorigenic features. It has also become evident that senescence is a highly dynamic and heterogenous process. Efforts to reconcile the beneficial and detrimental features of senescence suggest that physiological functions require the transient presence of senescent cells in the tissue microenvironment. Here, we propose the concept of a physiological "senescence life cycle," which has pathological consequences if not executed in its entirety.

Intraosseous synovial sarcoma of the distal ulna: a case report and review of the literature.
BMC Cancer. 2019; 19(1):116 [PubMed] Free Access to Full Article Related Publications
BACKGROUND: Synovial sarcoma is a relatively rare type of soft tissue sarcoma. The commonly observed symptom is a deep-seated palpable mass accompanied by pain or tenderness. Thus, it is considered a soft tissue sarcoma and rarely occurs primarily in bone. However, only few studies have been reported on intraosseous synovial sarcoma, and reports on cases with cytogenetic or molecular confirmation are even rarer. We report a case of intraosseous synovial sarcoma of the distal ulna that has been confirmed using histopathological examination and molecular analysis.
CASE PRESENTATION: A 77-year-old female was referred to our hospital with a 1-month history of right wrist pain after housework. Clinical and imaging findings suggested a benign bone tumor that was enhanced by Gd-DTPA. It was thought that the tumor was possibly an enchondroma. Initially, we planned to evaluate the benignancy of the tumor with intraoperative frozen section, followed by curettage and bone graft at one stage However, when considering carefully, characteristics of the tumor did not perfectly match those of any diagnostic categories including enchondroma. Therefore, an incisional biopsy was performed and revealed that the tumor was synovial sarcoma. Following an elaborate plan, the patient underwent a wide resection of the tumor at the distal part of the right ulna. Reverse transcription-polymerase chain reaction (RT-PCR) from the resected specimen and sequencing of RT-PCR products demonstrated a chimeric SYT-SSX1 transcript, confirming the diagnosis of synovial sarcoma.
CONCLUSIONS: Synovial sarcoma is seldom considered in differential diagnosis of bone tumors because it is difficult to line up such an unusual diagnosis as a differential diagnosis. When the lesion does not perfectly fit into any diagnostic category, when the initial image diagnosis appears unconvincing, biopsy and pathology are indicated, recalling Jaffe's triangle. According to these diagnostic processes, the patient successfully completed the treatment for this rare intraosseous synovial sarcoma, following a careful plan based on the preoperative diagnosis.

ATM rs189037 (G > A) polymorphism increased the risk of cancer: an updated meta-analysis.
BMC Med Genet. 2019; 20(1):28 [PubMed] Free Access to Full Article Related Publications
BACKGROUND: Rs189037 (G > A) is a functional single nucleotide polymorphism (SNP) in the Ataxia-telangiectasia mutated (ATM) gene that may be associated with the risk of cancer. We performed a meta-analysis to determine whether rs189037 polymorphism influences the occurrence of cancer and examined the relationship between this SNP and the etiology of cancer.
METHODS: Case-control studies were retrieved from literature databases in accordance with established inclusion criteria. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to evaluate the strength of the association between rs189037 and cancer. Subgroup analysis and sensitivity analysis also were performed.
RESULTS: After inclusion criteria were met, fifteen studies-comprising 8660 patients with cancer (cases) and 9259 controls-were included in this meta-analysis. Summary results indicated that an association was found between rs189037 and cancer risk. In the dominant model, the pooled OR using a random effects model was 1.207 (95% CI, 1.090-1.337; P < 0.001). The A allele of rs189037 increased the risk of lung cancer, breast cancer, and oral cancer. Results of subgroup analysis by ethnicity indicated that the SNP was associated with the risk of cancer among East Asian and Latino, but not Caucasian.
CONCLUSIONS: Results of this meta-analysis suggest that rs189037 is associated with the occurrence of lung cancer, breast cancer, and oral cancer as the risk factor. These data provide possible avenues for future case-control studies related to cancer.

Renal Medullary Carcinoma: a Report of the Current Literature.
Curr Urol Rep. 2019; 20(1):4 [PubMed] Related Publications
PURPOSE OF THE REVIEW: We present an updated report of renal medullary carcinoma (RMC), a rare and aggressive condition.
RECENT FINDINGS: There is a majority of male patients, of African descent, in the second or third decade of life. In differential diagnosis, other tumors, such as malignant rhabdoid tumor (MRT), vinculin-anaplastic lymphoma kinase (VCL-ALK) translocation renal cell carcinoma, and collecting duct carcinoma, may present difficulties. Abnormalities of tumor suppressor gene SMARCB1 have been found in RMC. Reported symptoms were hematuria, pain, weight loss, respiratory distress, palpable mass, cough, and fever. Most patients present with metastases at diagnosis. There is no definite recommended treatment, and protocols are extrapolated from other malignancies, with nephrectomy and systemic therapies being most frequently used. Response to treatment and prognosis remain very poor. RMC is a rare and aggressive tumor. Definitive diagnosis requires histological assessment and the presence of sickle-cell hemoglobinopathies.

Aneurysmal bone cyst of the frontal bone - A radiologic-pathologic correlation.
J Radiol Case Rep. 2018; 12(7):16-24 [PubMed] Free Access to Full Article Related Publications
We present a case of 27-year-old female who presented for a progressive frontal swelling with ipsilateral headache. Subsequent CT scan revealed an extradural and expansile multiloculated mass with thin and strongly enhanced septations and MRI evaluation showed internal hyperintensity on T2 with no restriction of diffusion and confirmed the multiple cystic spaces with enhancing septations and rare hemorrhagic fluid-fluid levels. Surgery was performed and diagnosis of aneurysmal bone cyst was made on frozen section. Identification of USP6 fusion gene by in situ hybridization technique permitted to confirm the diagnosis of primary ABC. Although aneurysmal bone cyst (ABC) of the skull is a very rare entity and accounts for 2-6% of all ABCs, we should think about it in front of osteolytic and cystic skull changes even with very few fluid-fluid levels. Following description of our case and differential diagnoses, we conduct a literature review of skull ABCs imaging characteristics and discuss the interest of USP6 rearrangement identification.

Infarcted Warthin tumor with mucoepidermoid carcinoma-like metaplasia: a case report and review of the literature.
J Med Case Rep. 2019; 13(1):12 [PubMed] Free Access to Full Article Related Publications
BACKGROUND: Warthin tumor is a common, benign, painless salivary gland neoplasm. Rarely, Warthin tumors show large areas of squamous metaplasia; such Warthin tumors are called metaplastic or infarcted Warthin tumors because they are occasionally accompanied with tumor necrosis. The histological distinction between mucoepidermoid carcinomas and the metaplastic portions of Warthin tumors can be challenging; without a genetic study, mucoepidermoid carcinomas can be misdiagnosed as metaplastic Warthin tumors. We report a case of infarcted Warthin tumor partly showing mucoepidermoid carcinoma-like epithelial metaplasia. Only two cases of infarcted Warthin tumor similar to our case have been reported.
CASE PRESENTATION: A 69-year-old Japanese man presented with a right parotid tumor. He had noticed the swelling on his right buccal region 1 year previously; the lesion had rapidly enlarged, with associated pain, 1 month previously. A radiological examination revealed a mass in the tail of the right parotid gland. Superficial parotidectomy was performed. On histological examination, the mass showed typical focal features of Warthin tumor; other areas showed coagulation necrosis of the tumor. These areas were surrounded by non-oncocytic epithelium comprising squamous and mucinous epithelial cells. Although cellular atypia of the non-oncocytic epithelium was not observed, a mixture of squamous and mucinous cells and lack of abundant lymphoid tissue mimicked low-grade mucoepidermoid carcinoma. Based on the results of fluorescence in situ hybridization, MAML2 gene rearrangement was not present in the typical portions of Warthin tumor and the mucoepidermoid carcinoma-like lesion. Therefore, a metaplastic or infarcted Warthin tumor was diagnosed. Our patient was disease-free 8 months after surgery.
CONCLUSIONS: Clinicians need to know that pain is a clinical symptom of infarcted/metaplastic Warthin tumor. Pathologists should be aware that a metaplastic Warthin tumor can mimic a low-grade mucoepidermoid carcinoma. Our case showed a mucoepidermoid carcinoma-like lesion that was confined near the area of tumor necrosis, and neither cytological atypia nor apparent invasive growth was present. These findings appeared to be histological clues of a metaplastic Warthin tumor rather than a mucoepidermoid carcinoma. Careful clinicopathological evaluation as well as genetic studies are needed to clarify the distinction between mucoepidermoid carcinoma and metaplastic portions of Warthin tumors.

Apatinib with EGFR-TKIs in advanced wild gene-type NSCLC: A case report.
Medicine (Baltimore). 2019; 98(1):e13924 [PubMed] Free Access to Full Article Related Publications
RATIONALE: For advanced non-small-cell lung cancer (NSCLC), targeted therapy and chemoradiotherapy are recommended as the first-line treatment. For patients with a performance status (PS) score over 2 and without gene mutation, however, only supportive treatment is provided and survival time is extremely short. We believe that more can be done to improve the patient's survival time and their quality of life.
PATIENT CONCERNS AND DIAGNOSES: A 65-year-old female came to our hospital due to "cough and pain and lack of movement in the left leg". The diagnosis was advanced wild gene-type lung adenocarcinoma and PS score over 2.
INTERVENTIONS AND OUTCOMES: She was treated in our clinic with apatinib and erlotinib and has had no progression of the disease for 15.4 months. Except for the presence of hand-foot syndrome and diarrhea, no other serious adverse reactions were seen.
LESSONS: For patients in poor physical condition and unacceptable of chemo-radiotherapy, apatinib combined with an epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) is a safe and effective therapeutic method for advanced wild gene-type NCSCL.

lncRNA SNHG1 negatively regulates miRNA‑101‑3p to enhance the expression of ROCK1 and promote cell proliferation, migration and invasion in osteosarcoma.
Int J Mol Med. 2019; 43(3):1157-1166 [PubMed] Free Access to Full Article Related Publications
Osteosarcoma (OS) is a rare malignant bone tumor that commonly occurs in children and adolescents and causes pain and swelling of the long bones of the legs and arms. Long non‑coding RNA (lncRNA) and micro (mi)RNA‑101 are important in the initialization and progression of OS. However, the mechanism underlying the role of the lncRNA and miRNA‑101 in OS remains to be fully elucidated. In the present study, through reverse transcription‑quantitative polymerase chain reaction analysis, it was first found that the lncRNA SNHG1 was upregulated and miRNA‑101‑3p was downregulated in OS tissues and cell lines. Second, the knockdown of lncRNA SNHG1 induced cell apoptosis and maintained the cell cycle at the G0/G1 phase, which decreased the overall cell viability. Furthermore, according to a dual‑luciferase assay and western blot analysis, miRNA‑101‑3p was found to be a target of the lncRNA SNHG1 in OS, which further regulated the expression of Rho‑associated coiled‑coil‑containing protein kinase 1 (ROCK1). It was found that the phosphoinositide 3‑kinase/ATK pathway was inactivated and that epithelial‑mesenchymal transition was activated in OS cell lines with overexpression of the lncRNA SNHG1. Taken together, in OS cell lines, the lncRNA SNHG1 acted as an oncogene, and miRNA‑101‑3p was considered a tumor suppressor. The lncRNA SNHG1 promoted OS cell proliferation, migration and invasion by downregulating the expression of miRNA‑101‑3p, which enhanced the expression of ROCK1.

Nonsmall cell lung cancer with rare exon 7 p.A289V mutation in the EGFR gene responds to Icotinib treatment: A case report.
Medicine (Baltimore). 2018; 97(51):e13809 [PubMed] Free Access to Full Article Related Publications
RATIONALE: Mutation p.A289V involving extracellular region of epidermal growth factor receptor (EGFR) exon 7 has not yet been reported in nonsmall cell lung cancer (NSCLC). Studies have shown p.A289V mutation responding to tyrosine kinase inhibitors (TKIs) in glioblastoma cell lines suggesting the point mutation as a potential therapeutic target. However, sufficient evidence of the effect of TKI treatment on the p.A289V mutation involved in NSCLC is not available.
PATIENT CONCERNS: An 80-year-old nonsmoker male with lung mass was suffering from severe bone pain.
DIAGNOSIS: Needle biopsy and positron emitted tomography/computed tomography were performed. The patient was diagnosed with advanced NSCLC adenocarcinoma with bone and lymphatic metastasis. Next-generation sequencing of circulating tumor DNA was performed, which identified a p.A289V mutation in the EGFR gene of the patient.
INTERVENTIONS: Our patient refused to receive chemotherapy and tried Icotinib treatment.
OUTCOMES: Our patient had a partial response to Icotinib after treatment for 5 months during the therapeutic trial by TKIs. The patient showed adverse symptoms of mild diarrhea and rash (Common Terminology Criteria for Adverse Events grade 1) during the treatment.
LESSONS: In this case, Icotinib prevented completion of the signal transduction cascade of p.A289V mutant in NSCLC. Our finding may expand the EGFR mutation spectrum for TKI treatment in NSCLC. However, the finding needs to be confirmed at a larger scale with NSCLC in Chinese and other populations.

MiR-21 Participates in the PD-1/PD-L1 Pathway-Mediated Imbalance of Th17/Treg Cells in Patients After Gastric Cancer Resection.
Ann Surg Oncol. 2019; 26(3):884-893 [PubMed] Related Publications
BACKGROUND: The programmed cell death-1/programmed cell death-ligand 1 (PD-1/PD-L1) pathway has been shown to be involved in trauma-induced immunosuppression and to influence CD4
METHODS: In the present study, we analyzed the percentages of T-helper (Th)-17/regulatory T (Treg) cells and PD-1/PD-L1 expression on peripheral blood mononuclear cells (PBMCs) during the perioperative period. We also detected the secretion of interleukin (IL)-17 and transforming growth factor (TGF)-β1 using enzyme-linked immunosorbent assays (ELISAs). Furthermore, PBMCs isolated from patients were transfected with or without adenovirus-short hairpin-PD-1 (Ad-sh-PD1), pre-miR-21 or adenovirus-green fluorescent protein (Ad-GFP), and the percentages of Th17/Treg cells and related transcription factors were measured.
RESULTS: In patients who underwent gastric cancer resection, the number of Th17 cells decreased, whereas the number of Treg cells increased, accompanied by an increased expression of PD-1/PD-L1. In addition, the expression of RORγt and IL-17 decreased, whereas the expression of Foxp3 and TGF-β1 increased. In vitro, silencing PD-1 via Ad-sh-PD1 promoted the expression of miR-21 and increased the percentage of Th17 cells, but decreased the percentage of Treg cells. The overexpression of miR-21 increased the percentage of Th17 cells but decreased the percentage of Treg cells.
CONCLUSIONS: Our study demonstrated that gastric cancer resection altered the balance of Th17/Treg cells and increased PD-1/PD-L1 expression. In the in vitro experiments, the transfection of Ad-sh-PD1 ameliorated Th17/Treg cell imbalance partially by increasing the expression of miR-21.

A novel PAX5 rearrangement in TCF3-PBX1 acute lymphoblastic leukemia: a case report.
BMC Med Genomics. 2018; 11(1):122 [PubMed] Free Access to Full Article Related Publications
BACKGROUND: Chromosome translocations are a hallmark of B-cell precursor acute lymphoblastic leukemia (BCP-ALL). Additional genomic aberrations are also crucial in both BCP-ALL leukemogenesis and treatment management. Herein, we report the phenotypic and molecular cytogenetic characterization of an extremely rare case of BCP-ALL harboring two concomitant leukemia-associated chromosome translocations: t(1;19)(q23;q13.3) and t(9;17)(p13;q11.2). Of note, we described a new rearrangement between exon 6 of PAX5 and a 17q11.2 region, where intron 3 of SPECC1 is located. This rearrangement seems to disrupt PAX5 similarly to a PAX5 deletion. Furthermore, a distinct karyotype between diagnosis and relapse samples was observed, disclosing a complex clonal evolution during leukemia progression.
CASE PRESENTATION: A 16-year-old boy was admitted febrile with abdominal and joint pain. At clinical investigation, he presented with anemia, splenomegaly, low white blood cell count and 92% lymphoblast. He was diagnosed with pre-B ALL and treated according to high risk GBTLI-ALL2009. Twelve months after complete remission, he developed a relapse in consequence of a high central nervous system and bone marrow infiltration, and unfortunately died.
CONCLUSIONS: To our knowledge, this is the first report of a rearrangement between PAX5 and SPECC1. The presence of TCF3-PBX1 and PAX5-rearrangement at diagnosis and relapse indicates that both might have participated in the malignant transformation disease maintenance and dismal outcome.

SKA1 overexpression is associated with poor prognosis in hepatocellular carcinoma.
BMC Cancer. 2018; 18(1):1240 [PubMed] Free Access to Full Article Related Publications
BACKGROUND: SKA1, an important mitosis protein, has been indicated in the initiation and progression of several malignancies. However, its clinical significance in hepatocellular carcinoma (HCC) remain to be elucidated.
METHODS: mRNA expression of SKA1 was examined in 126 HCC and paired non-neoplastic tissues using real-time PCR and validated in The Cancer Genome Atlas (TCGA) database. SKA1 protein expression was detected using immunohistochemistry in the 126 HCC tissues and its associations with clinicopathological parameters and prognosis were analyzed. Hierarchical cluster analysis and gene set enrichment analysis (GSEA) were performed in selected Gene Expression Omnibus data sets.
RESULTS: SKA1 mRNA expression was significantly elevated in HCC tissues from both local hospital and TCGA database. Immunohistochemistry revealed that increased SKA1 expression was present in 65 of the 126 cases and was significantly associated with higher serum alpha-fetoprotein concentration, larger tumor size and higher TNM stage. Patients with positive SKA1 expression showed significantly worse overall and relapse-free survival. Multivariate Cox regression analysis revealed that SKA1 was an independent predictor of patient prognosis. Gene expression profiling analysis of public data showed that high-SKA1 expression HCC tissues had similar gene expression profiles with fetal liver tissues. Moreover, GSEA showed that genes up-regulated in high SKA1 HCC subgroup were significantly enriched in cell cycle pathway, while genes down-regulated were significantly enriched in apoptosis pathway.
CONCLUSIONS: Our findings indicate that the oncofetal gene SKA1 might be involved in the progression of the HCC and could serve as a prognostic marker for HCC.

Profiles of genomic alterations in primary esophageal follicular dendritic cell sarcoma: A case report.
Medicine (Baltimore). 2018; 97(48):e13413 [PubMed] Free Access to Full Article Related Publications
RATIONALE: Follicular dendritic cell (FDC) sarcoma is a rare tumor with FDC differentiation that typically arises within lymph nodes but can also occur extranodally. To date, the primary esophageal FDC sarcoma has not been reported in the English literature.
PATIENT CONCERNS: We described a 67-year-old female who foremostly presented with dysphagia, and the patient was readmitted due to a dry cough and pain of his right shoulder 2 years after initial treatment.
DIAGNOSES: Primary esophageal FDC sarcoma with the right superior mediastinal lymph node metastasis.
INTERVENTIONS: The esophageal tumor was removed by endoscopic submucosal dissection at the first hospitalization. At the second hospitalization 2 years after the initial visit, the tracheal stent loaded with (125) iodine radioactive seeds was placed. The profiles of genetic variations and immunotherapeutic biomarkers were also explored by next-generation sequencing protocol from the patient's blood, esophageal primary, and mediastinal metastatic tumor samples.
OUTCOMES: The patient's symptom transitorily relieved, but she gave up further treatment and died 2 months after the tracheal stent was placed. As for the genomic alterations, we found 9 gene mutations in all the samples, including checkpoint kinase 2(CHEK2), FAT atypical cadherin 1 (FAT1), tumor protein 53 (TP53), DPYD, ERBB2 interacting protein (ERBB2IP), FBXW7, KMT2D, PPP2R1A, TSC2, whereas amplification of MYC was only in the metastatic example. The analysis of clonal evolution and phylogenetic tree showed the propagation and replay of polyclonal esophageal FDC sarcoma. At the same time, the detection of biomarkers for immunotherapy revealed microsatellite stable and mismatch repair-proficient (pMMR), which predicted a relatively poor anti-programmed death (PD-1)/programmed death ligand (PD-L1) immunotherapy outcome. On the contrary, the tumor mutational burdens were 10 mutations per 1 million bases in both the primary and metastatic tumor sample, which ranked the top 23.3% in solid tumors mutational burdens database of Geneseeq and might be a good predictor of the efficacy of anti-PD-1/PD-L1 immunotherapy.
LESSONS: To the best of our knowledge, this case report announced the first case of extranodal primary esophageal FDC sarcoma in the world, and firstly revealed its unique genetic alterations profiles, which might contribute to further in-depth study of this rare disease.
