Protein levels of PTEN/Akt/GSK3β. a Expressions of various proteins in the BMSCs in the four treatment groups [normal glucose (NG), high glucose (HG), high glucose plus uncarboxylated osteocalcin (HG + GluOC), and high glucose plus siTP63 (HG + siTP63)]. b Relative protein expressions obtained by grayscale scanning. Negative control siRNA was used in all the RNA interference experiments. *P < 0.05, **P < 0.01 versus NG; #P < 0.05, ##P < 0.01 versus HG
