SNHG1 overexpression alleviates BMSC osteogenesis differentiation by targeting miR-101. (A) miR-101 and DKK1 expression levels in BMSCs transfected with miR-101 mimics and mimics-NC. (B) DKK1 expression levels in BMSCs following co-transfection with pcDNA-SNHG1 and miR-101 mimics. (C) The expression levels of RUNX2, OPN and OCN expression in BMSCs co-transfected with pcDNA-SNHG1 and miR-101 mimics. (D) ALP activity and (E) Alizarin Red staining in BMSCs co-transfected with pcDNA-SNHG1 and miR-101 mimics. *P<0.05, **P<0.01 and ***P<0.001. SNHG1, small nucleolar RNA host gene 1; BMSC, bone mesenchymal stem cell; miR, microRNA; DKK1, dickkopf WNT signaling pathway inhibitor 1; NC, negative control; RUNX2, RUNX family transcription factor 2; OPN, osteopontin; OCN, osteocalin.
