MicroRNAs (miRNAs) play critical roles in multiple processes of skeletal development. A global reduction of miRNAs in growth plate chondrocytes results in defects in both proliferation and differentiation; however, specific microRNAs responsible for these defects have not been identified. In this study, we provide evidence that let-7 miRNAs and microRNA-140 (miR-140), among other miRNAs express...

BACKGROUND In this study, we investigated the functional correlation between microRNA-210 (miR-210) and gene of F-box protein 31 (FBXO31) in regulating breast cancer. METHODS Dual-luciferase assay and quantitative real-time polymerase chain reaction were used to investigate the binding of miR-210 with FBXO31 and their expression patterns in breast cancer. miR-210 was inhibited in breast cance...

Autophagy is known to have a cytoprotective role under various cellular stresses; however, it also results in robust cell death as an important safeguard mechanism that protects the organism against invading pathogens and unwanted cancer cells. Autophagy is regulated by cell signalling including microRNA (miRNA), a post-transcriptional regulator of gene expression. Here, we show that geneticall...

Abstract Background Dysregulated miRNAs are involved in carcinogenesis of the breast and may be used as prognostic biomarkers therapeutic targets during cancer process. The purpose this study was to explore effect miR-105-3p on tumourigenicity its underlying molecular mechanisms. Methods Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) applied detect expression tissues cel...

MicroRNAs (miRNAs), a class of small noncoding RNA molecules, can manipulate the expressions of endogenous tumor-related genes, and are implicated in the development and progression of a wide type of tumors. In this study, the investigation from real-time quantitative PCR revealed that miRNA-16-5p was downregulated in breast carcinoma tissues and cells, coupled with the elevations of HIF-α and ...

The 40,000 neurons of the medulla, the largest visual processing center of the Drosophila brain, derive from a sheet of neuroepithelial cells. During larval development, a wave of differentiation sweeps across the neuroepithelium, converting neuroepithelial cells into neuroblasts that sequentially express transcription factors specifying different neuronal cell fates. The switch from neuroepith...

Curcumin, a natural polyphenol compound, exhibits tumor suppressive activity in a wide spectrum of cancers, including nasopharyngeal carcinoma cells. However, the exact molecular mechanisms governing this tumor suppressive activity remain elusive. Multiple studies have revealed that miRNAs are critically involved in tumorigenesis, indicating that targeting miRNAs could be a therapeutic strategy...

MicroRNAs are well established regulators of Inflammatory Bowel Disease (IBD), such as Crohn’s disease (CD) and ulcerative colitis (UC). Furthermore, gasotransmitters including nitric oxide (NO), carbon monoxide (CO) and hydrogen sulphide (H2S) also seem to play important role in this disease pathogenesis. In the present study, we aimed to investigate the relationship between microRNAs and gaso...

Increasing evidence has revealed that miR-199a-5p is actively involved in tumor invasion and metastasis as well as in the decline of breast cancer tissues. In this research, overexpression of miR-199a-5p weakened motility and invasion of breast cancer cells MCF-7 and MDA-MB-231. Upregulation of Ets-1 increased breast cancer cell invasion, but the mechanism by which miR-199a-5p modulates activat...
