microRNAs (miRs) are endogenous small non-coding RNAs that are aberrantly expressed in various carcinomas. miR-152 and miR-148a have not been comprehensively investigated in ovarian cancer. Thus, the aim of this study was to identify the role of miR-152 and miR-148a in epithelial ovarian cancer. Total RNA was extracted from tissues of 78 patients ...

Background: Hepatocellular carcinoma (HCC) is a leading cause of cancer-related death worldwide, mainly due to its high rates of postoperative recurrence and metastasis. Please remove, it currently ranks as the third most common cause of cancer-related deaths. MiRNAs are a set of small, single-stranded, non-coding RNA molecules that negatively regulate gene expression at the post-transcriptiona...

MicroRNAs (miRNAs) have been widely accepted as a class of gene expression regulators which post-translationally regulate protein expression. These small noncoding RNAs have been proved closely involved in the modulation of various pathobiological processes in cancer. In this research, we demonstrated that miR-148a expression was significantly down-regulated in gastric cancer tissues in compari...

The hepatic low-density lipoprotein receptor (LDLR) pathway is essential for clearing circulating LDL-cholesterol (LDL-C). While the transcriptional regulation of LDLR is well-characterized, the post-transcriptional mechanisms which govern LDLR expression are just beginning to emerge. Here, we developed a high-throughput genome-wide screening assay to systematically identify microRNAs (miRNAs) ...

Current standard practices for treatment of cancers are less than satisfactory because of recurrence mediated by cancer stem cells (CSCs). Caffeic acid (CaA) is a novel anti-tumor agent that inhibits proliferation, migration, and invasion in human cancer cells. However, little is known about the functions of CaA in regulating CSCs-like properties and the potential molecular mechanisms. Here, we...

Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related mortality worldwide. Current standard practices for treatment of HCC are less than satisfactory because of cancer stem cells (CSCs)-mediated post-surgical recurrence. For this reason, targeting the CSCs or the cancer cells with CSCs-like properties has become a new approach for the treatment of HCC. GLA exhibits anti-tu...

Breast cancer remains the most prevalent cancer among women worldwide. The expression of estrogen receptor-α (ER-α) is an important marker for prognosis. ER-α status may be positive or negative in breast cancer cells, although the cause of negative or positive status is not yet fully characterized. In the present study, the expression of ER-α and miRNA-148a was assessed in two breast cancer cel...

Long-lived antibody-secreting plasma cells are essential to establish humoral memory against pathogens. While a regulatory transcription factor network has been established in cell differentiation, the role of miRNAs remains enigmatic. We have recently identified miR-148a as most abundant miRNA primary mouse and human cells. To determine whether this signature controls vivo development B into l...

AIM Development of robust prognostic and/or predictive biomarkers in patients with colorectal cancer (CRC) is imperative for advancing treatment strategies for this disease. We aimed to determine whether expression status of certain miRNAs might have prognostic/predictive value in CRC patients treated with conventional cytotoxic chemotherapies. METHODS We studied a cohort of 273 CRC specimens...

BACKGROUND MicroRNAs are associated with tumor genesis and progression in various carcinomas. MicroRNA-148a (miR-148a) was reported to have low expression in gastrointestinal cancers, and might be regulated by promoter region DNA methylation. METHODS Bisulfite-modified sequencing was used to determine the promoter region DNA methylation status of human gastrointestinal cancer cell lines. Expr...
