Protein expression of apoptotic markers. (A) p53 and NAG-1 protein expression in LoVo cells after different exposure times to NCX 4040. (B) NAG-1 protein expression in LRWZ cells after different exposure times to NCX 4040. (C) Cytochrome c, caspase-9 and -3 protein expression in LoVo cells: lane a, untreated; lane b, 6-hour NCX 4040 exposure (10 μM). (D) Cytochrome c, caspase-9 and -3 protein expression in LRWZ cells: lane a, untreated; lane b, 14-hour NCX 4040 exposure (50 μM).
