| Function Description | Adipose-derived mesenchymal stem cells (ADSCs) are an important source of stem cells for tissue repair and regeneration but the regulatory mechanism of stem cell differentiation is still unclear. Runt-related gene 2 (Runx2) is a bone-specific transcription factor that plays an important role in promoting osteogenic differentiation. Protein levels of Runx2 are regulated by non-coding RNA. In order to identify the regulatory mechanism underlying non-coding RNA regulation of Runx2, we employed bioinformatics analysis, quantitative reverse transcription PCR (qRT-PCR), osteoblast differentiation induction, immunohistochemical and bifluorescein reporter experiments. The results showed that expression of long non-coding RNA (lncRNA) metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) and Runx2 was increased in ADSCs induced in osteogenic differentiation media for 21 days, while miR-30 expression was downregulated. qRT-PCR and alkaline phosphatase (ALP) histochemical staining assays demonstrated that knockdown of lncRNA MALAT1 or overexpression of miR-30 suppressed Runx2-mediated osteoblast differentiation by suppressing osteocalcin (OCN), osteopontin (OPN) and osterix (OSX) expression. Overexpressing Runx2 reversed the inhibitory effect of miR30 on osteogenic differentiation of ADSCs. Bifluorescein report experiments confirmed that miR-30 is a potential target of lncRNA MALAT1 and Runx2 is a potential target of miR-30. Taken together, the results suggested that the expression of lncRNA MALAT1 promoted Runx2-mediated osteogenic differentiation of ADSCs by targeting miR-30 |
