Effects of Cheongja#3 on caspases activities in HaCaT. (a) Cells were treated with Cheongja#3 (10, 100 μg/ml) for 24 hr. Afterward medium containing extract was removed and then treated with H₂O₂ for another 24 hr. Caspase‐3 enzymatic activities were determined in HaCaT cells. (b) Cleaved caspase‐3, caspase‐6, and, caspase‐7 protein levels were assessed by Western blotting. (c) MAPK protein p38, JNK, ERK protein levels were assessed by Western blotting. *p < 0.05 versus H₂O_2‐treated cells
