Effects of the TPF on Cathepsin K, MMP-9, MMP-13 and β-actin expression in primary osteoclast cells. a The TPF down regulated Cathepsin K, MMP-9 and MMP-13 proteins expression and β-actin served as the control for the protein assay, b cathepsin K activity, c MMP-9 activity and d MMP-13 activity. The data were expressed as the mean ± SD (n = 4) for each group. *p < 0.05
