Dose-dependent effect of urushiol on the levels of apoptosis-related proteins in MKN-45 cells. MKN-45 cells were treated with the indicated concentration of urushiol for 48 h. Total cell lysates were prepared and the indicated protein levels were determined by Western blotting. β-actin was used as an internal loading control. A representative blot is shown from three independent experiments. p53 (w), wild type p53.
