Ultraviolet A activates JNK and p38MAPK pathways. Western blotting analysis was performed to detect the activation of JNK (a) and p38 (b). The representative data of three independent experiments are shown. *P < 0.05 versus control. UVA: Ultraviolet A; P-: Phospho-; GAPDH: Glyceraldehyde-3-phosphate dehydrogenase; MAPK:Mitogen-activated protein kinase.
