... levels of Runx2, ALP, bone morphogenetic protein (BMP) 2, and OC and lower expression of PPARγ than the MPS group. In the in vivo study, ICA prevented bone loss in a rat model of GC-related ONFH as shown by micro-CT scanning, histological and immunohistochemical analyses. Conclusions: ICA is an effective...

... with overexpression or with suppression of miR-196b were estimated sequentially. Next, dual luciferase activity assay was performed to clarify whether Runx2 was a direct target of miR-196b. Finally, the expressions of main factors associated with epithelial mesenchymal transition (EMT), PI3K/AKT/GSK3β, Smad, and JNK...

... in the posterior longitudinal ligament through the regulation of extracellular signal-regulated kinases (ERK) activity by converging on Runt-related transcription factor 2 (Runx2) activity. In this study, we mapped the activity of Connexin 43 to ERK and Runx2 by extracting longitudinal ligament cell for culture...

... cells, whereas the depletion of miR-23a resulted in the opposite effects. MiR-23a suppressed the transcription of RUNX2 and CXCL12 by binding to the 3' UTRs of these mRNAs. The cellular function of miR-23a is RUNX2/CXCL12-dependent, and the overexpression of RUNX2 or CXCL12 rescued the impaired cell...

... of endogenous miR-205 was decreased in HASMCs during β-glycerophosphate-induced calcification. Overexpression of miR-205 inhibited the differentiation of HASMCs into osteoblast-like cells, as evidenced by a decrease in ALP activity, osteocalcin secretion, and Runx2 expression, whereas miR-205 depletion enhanced...

... knockdown inhibited strontium-stimulated expression of osteogenic markers. Finally, the transcriptional activity and phosphorylation level of Runx2 was significantly increased in response to strontium treatment in MSCs. PD98059 and Ras siRNA inhibited the effect of strontium on Runx2 activation. Taken...
