Activation of ERK with induction of apoptosis by various chemopreventive and chemotherapeutic agents [39-41]. In fact, oxidants have been shown to activate ERK by taking over the growth factor receptor signaling pathways [42-46]. Moreover, ERK may get activated in response to DNA damage and can phosphorylate p53 in vitro [23,24,47-49]. We found that exposure of Capan-2 or BxPC-3 cells with apoptos
