Apoptosis Effects of Dihydrokaempferol Isolated from Bauhinia championii on Synoviocytes

Figure 5

Dihydrokaempferol induced the activation of caspases and the cleavage of PARP in RA-FLSs. (a) Representative western blot and (b) the relative optical densities analysis of the levels of cleaved caspase-3, cleaved caspase-9, and cleaved PARP. β-actin was used as the internal controls. Three independent experiments were done. < 0.05 and < 0.01 versus the control group.
