MicroRNAs (or miRNAs) are small non-coding RNAs (21-25 nucleotides) that are involved in a wide range of activities related to the development and differentiation of cells. Comparison of the miRNA expression profiles of mouse P19 embryonic carcinoma cells with those of differentiated neural stem cells showed that the expression level of 65 miRNAs changed (2-fold) after differentiation. MiR-124a...

The epigenetic mechanisms in regulation of genes' expression seem to be another field of research that gains land in genetic association studies of rheumatoid arthritis (RA) susceptibility factors. Recently, a new class of molecules has been discovered, the microRNAs (miRNAs). miRNAs are related to post-transcriptional regulation of genes' expression. Different expression patterns of mir-146a, ...

MicroRNAs (miRNAs) are non-coding RNAs that bind to target mRNA leading to translational arrest or mRNA degradation. To study miRNA-mediated regulation of osteogenesis and chondrogenesis, we compared the expression of 35 miRNAs in osteoblasts and chondroblasts derived from mouse marrow stromal cells (MSCs). Differentiation of MSCs resulted in up- or downregulation of several miRNAs, with miR-19...

The detection of microRNAs (miRNAs) at single-cell resolution is important for studying the role of these posttranscriptional regulators. Here, we use a dual-fluorescent green fluorescent protein (GFP)-reporter/monomeric red fluorescent protein (mRFP)-sensor (DFRS) plasmid, injected into zebrafish blastomeres or electroporated into defined tissues of mouse embryos in utero or ex utero, to monit...
