Figure 8.Changes in the SIRT1/p53/p21 axis in osteogenic cells after LMV. (A) BMSCs were treated with LMV and were harvested to detect the protein levels of SIRT1, p53, and p21 using western blotting ; (B) Osteoblasts were treated with LMV and were harvested to detect the protein levels of SIRT1, p53, and p21 using western blotting ; (C) Osteocytes were treated with LMV and were harvested to detect the protein levels of SIRT1, p53, and p21 using western blotting . *P < 0.05 vs. old female rats.
