BACKGROUND Schizophrenia is a highly heritable neurodevelopmental disorder. A genetic variant of microRNA-137 (miR-137) has yielded significant genome-wide association with schizophrenia, suggesting that this miRNA plays a key role in its etiology. Therefore, a molecular network of interacting miR-137 targets may provide insights into the biological processes underlying schizophrenia. METHODS...

microRNAs, frequently deregulated in human cancer, have been implicated in the progression of hepatocarcinogenesis. Here, we show that microRNA (miR)-137 is significantly down-regulated in hepatocellular carcinoma (HCC). Its decreased expression is associated with vein invasion, incomplete Involucrum, and distant metastasis. Multivariate analysis suggests that miR-137 is an independent indicato...

In the present study, we evaluated the mechanisms of CDC42 in association with the microRNA-137 (miR-137)-induced inhibition of human hepatocellular carcinoma (HCC). The gene expression levels of miR-137 were evaluated in HCC cell lines. Direct association of miR-137 with its downstream target, cell division control protein 42 (CDC42), was evaluated by dual-luciferase assay, western blot analys...

MicroRNA-137 (miR-137) was reported to be dysregulated in several human cancers. However, the function and mechanism of miR-137 in non-small cell lung cancer (NSCLC) is still unclear. In the current study, we explored the role of miR-137 in NSCLC progression. Using qRT-PCR, our data showed that miR-137 was significantly down-regulated in NSCLC tissues and cell lines. In vitro functional assay, ...

BACKGROUND Oxidative stress, inducing cardiomyocyte apoptosis or myocardial ischemia, is the major denominator of many cardiac diseases. In this study, we intended to explore the regulatory function of microRNA-137 (miR-137) in oxidative stress-induced cardiomyocyte apoptosis. MATERIAL AND METHODS Cardiomyocytes were extracted from newborn C57BL/6 mice and cultured in vitro. Apoptosis was ind...

Up to date, miR-137 has been demonstrated as a tumor suppressor in many kinds of human malignancies. In the present study, we conducted transfection, western blot and RT-PCR to explore the role of miR-137 in the development of human glioblastoma (GBM). Here, we found that miR-137 expression was obviously down-regulated in GBM tissues and cells rather than matched non-tumor tissues and NHA cells...

Carboxyl-terminal binding protein 1 (CtBP1) is a transcriptional co-repressor that represses expression of various tumor suppressor genes. In the present study, we identified miR-137 as a potential regulator of CtBP1 expression in melanoma cells. Expression of miR-137 in melanoma cell lines was found to inversely correlate with CtBP1 levels. Target Scan predicted a putative site for miR-137 wit...

The molecular mechanisms underlying colorectal cancer (CRC) development remain elusive. In this study, we examined the miRNA and mRNA expressions in the adenoma-carcinoma sequence (ACS), a critical neoplastic progression in CRC development. We found that miR-137 was down-regulated in all adenoma and carcinoma tissues. Low miR-137 levels were correlated negatively with tumor progression and meta...

BACKGROUND In ovarian cancer (OC) cells, Snail was reported to induce the epithelial-to-mesenchymal transition (EMT), which is a critical step in OC metastasis. At present little is known about controlling Snail expression in OC cells by using specific microRNAs (miRNAs). METHODS We first used a computational target prediction analysis to identify 6 candidate miRNAs that bind to the 3'-untran...

OBJECTIVE MiR-137 has been reported to serve as a tumor suppressor in non-small cell lung cancer (NSCLC). However, the potential mechanism remains largely unclear. The present study aimed to explore the potential molecular mechanisms by which miR-137 regulated NSCLC. MATERIALS AND METHODS Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was used to quantify the expressio...
