The effects of 14days exposure to sublethal concentrations of endosulfan (10 and 40gL(-1)) were investigated in mRNA- P450 1A expression, antioxidant enzymes (SOD and CAT) activity and histopathological alterations of Persian sturgeon (Acipenser persicus) fingerlings with weights of 3-5g. The results illustrated that the relative mRNA- P450 1A expression level significantly increased (P<0.05) compared to the control group. Highest significant increase (P<0.05) was observed on the first day, then decreased towards day 14 of exposure. The SOD and CAT activity showed a significant increase in fish exposed to different concentrations up to day 7, then activity decreased on day 14 in fish of all treated groups. Although signs of tissue lesions were observed on day 4, they increased from day 7 and reached the highest level on day 14. The magnitude of all changed studied parameters (gene expression, enzymes and histopathological) follows a concentration-dependent manner.
