Fig. 6. Rosmarinic acid (RA) inhibits UVB-induced antioxidant enzyme imbalance and apoptosis in the mouse dorsal skin tissue. Mice were administrated with RA (0.01 or 0.1 mg/mL) or padimate O before they were exposed to UVB. (A) Tissue lysates from skin samples were analyzed via western blot to detect the expression of CAT and SOD1. (B) Protein expression of Bcl-2, Bax, cleaved caspase-9 and caspase-3, and cleaved PARP were detected using their specific antibodies. (A, B) Actin was used as a loading control.
