Regulation of Osteoblast Differentiation by miR-148b, miR-181b, and miR-181c
PúblicoMesenchymal stem cells are directed towards the osteoblast lineage and bone cell formation, regulated at transcriptional, post-transcriptional, and translational levels by various signaling pathways and transcription factors. MicroRNAs are small, non-coding RNA strands that regulate protein synthesis by binding to mRNA and inhibiting translation. The expression of many microRNAs have been shown to be modulated during osteoblast differentiation. We observed that expression of miR-148b, miR-181b, and miR-181c are upregulated during osteoblast differentiation of MC3T3 cells. We found that miR-181b and miR-181c induce the expression of differentiation markers and support osteoblast differentiation, possibly by targeting the inhibitors of differentiation such as FGF21, Bcl2, Smad4 and Nlk.
