The expression of miR-145 with tumor suppressor function is decreased in lung cancer cells. Epidermal growth factor receptor (EGFR) signaling pathway is abnormally activated in lung cancer cells. It is not clear whether the EGFR signaling pathway is involved in the regulation of miR-145 expression in lung cancer. In the present study, we found that the reduction of miR-145 was associated with E...

AIM To determine the potential roles of CD4 and microRNA (miR)-145 in gastric cancer. METHODS The levels of CD44 and miR-145 were determined in gastric cancer cells. Quantitative real-time polymerase chain reaction was used to measure to the level of CD44 mRNA. A luciferase reporter assay and western blotting were performed to examine the effect of miR-145 on CD44 expression. Tumor sphere and...

Multiple myeloma (MM) is a disease with an adverse outcome and new therapeutic strategies are required to combat this disease. It is well known that tumor‑suppressor microRNA (miRNA) acts as a new potential anticancer agent. Accumulating evidence showed that microRNA-145 (miR-145) is a candidate tumor suppressor miRNA. However, whether miR-145 is involved in the development and progression of M...

MicroRNA (miR)-145-5p has been reported to function as a suppressor of cancer and plays an important role in cancer invasiveness. Epithelial-mesenchymal transition (EMT) is an important process in cancer invasion and migration. However, the involvement of miR-145-5p in EMT in human gastric cancer (GC) remains unclear. In this study, we aimed to investigate the molecular mechanisms by which miR-...

Profiling of microRNA expression in human cancers has highlighted downregulation of miR-145 as a common event in epithelial malignancies. Here, we describe recurrent underexpression of miR-145 in hepatocellular carcinoma (HCC) and the identification of a biological pathway by which miR-145 exerts its functional effects in liver tumorigenesis. In a cohort of 80 HCC patients, quantitative reverse...

MicroRNA-145 (miR-145) is considered to play key role in many cellular processes, such as proliferation, differentiation and apoptosis by inhibiting target gene expression. The transcriptional regulation of cardiovascular development requires precise spatiotemporal control of gene expression. We are beginning to understand the functions of miRNA-145 played during essential biological processes ...

The present study aims to investigate the effects and underlying mechanisms of miRNA-145 (miR-145) in rat models of chronic constriction injury (CCI). Rats were randomly divided into control, sham, CCI, agomiRNA (agomiR)-normal control (NC) and agomiR-145 groups (n=25 in each group); in addition, 30 rats with CCI were divided into small hairpin (sh)RNA-NC and shRNA-ras responsive element bindin...

BACKGROUND AND OBJECTIVES Biliary atresia (BA) is a pediatric liver disease characterized by fibro-obliteration and obstruction of the extrahepatic biliary system, that invariably leads to cirrhosis and even death, if left untreated for extended time. However, its pathology and etiology still remained unknown. In this study, we tested the expression of adducin 3 (ADD3), the gene identified as a...
