Schematic representation of the molecular interplay of protective effect of curcumin and resveratrol against B(a)P induced testicular germ cell apoptosis. B(a)P enters the cell, associates with AhR and induces CYP1A1 promoter activity. B(a)P generates oxidative stress, activates MAPKs (ERK1/2,p38 MAPK,JNK1/2) and p53. B(a)P turns-on intrinsic and extrinsic apoptotic pathway in germ cells. Combinatorial treatment of curcumin and resveratrol prevent CYP1A1 production and quenches oxidative stress. They synergistically attenuate MAPK activation and p53 activation. Curcumin and resveratrol protect testicular germ cells from B(a)P induced apoptosis. B(a)P, Benzo(a)Pyrene; Cur, Curcumin; Res, Resveratrol.
