objective: micrornas (mirnas) are noncoding rnas that function as key regulators of diverse biological activities such as cellular metabolism, cell proliferation and cell cycle regulation. recent studies have indicated the high potential of these small molecules to control stem cell differentiation into desired cells. the aim of present study is to investigate the possible effect of let-7f on e...

Background and Aims: Human adipose tissue-derived stem cells (hASCs) are considered as an attractive source of regenerative stem cells, mainly because of their higher proliferation rate, more accessibility and hepatocyte like properties as compared to mesenchymal stem cells isolated from other tissues. Numerous studies have described the beneficial use of adipose tissue-derived stem cells for g...

Previous studies have examined the arrangement of regulatory elements along the apolipoprotein B (apoB) promoter region (-3067 to +940) and a promoter fragment extending from nucleotides -150 to +124 has been demonstrated to be essential for transcriptional activation of the apoB gene in hepatic and intestinal cells. It has also been shown that transcriptional activation of apoB requires a syne...

Based on plasma endotoxin/toll-like receptor-4/nuclear factor-kappa B signal pathway to investigate the protective effect of soothing liver mixture mice with injury induced by antituberculosis drugs. A total 72 Sprague Dawley male rats were randomly divided into blank control group, model silymarin group and (low, medium high dosage), 12 in each group. 16 h after last administration, pathologic...

MiRNAs have been reported as CIS-acting elements of several hemostatic factors, however, their mechanism as TRANS-acting elements mediated by a transcription factor is little known and could have important effects. HNF4α has a direct and important role in the regulation of multiple hepatic coagulation genes. Previous in vitro studies have demonstrated that miR-24-3p and miR-34a-5p regulate HNF4...

AIM To uncover the role of hepatocyte nuclear factor 4 alpha (HNF4α) in regulating hepatic expression of microRNAs. METHODS Microarray and real-time PCR were used to determine hepatic expression of microRNAs in young-adult mice lacking Hnf4α expression in liver (Hnf4α-LivKO). Integrative genomics viewer software was used to analyze the public chromatin immunoprecipitation-sequencing datasets ...
