Background Ochratoxin A(OTA)is a toxin widely found in aquafeed ingredients,and hypoxia is a common prob-lem in fish *** practice,aquatic animals tend to be more sensitive to hypoxia while feeds are contaminated with OTA,but no studies exist in this *** research investigated the multiple biotoxicities of OTA and hypoxia combined on the liver of grass carp and explored the mitigating effect of curcumin(CUR).Methods A total of 720 healthy juvenile grass carp(11.06±0.05 g)were selected and assigned randomly to 4 experi-mental groups:control group(without OTA and CUR),1.2 mg/kg OTA group,400 mg/kg CUR group,and 1.2 mg/kg OTA+400 mg/kg CUR group with three replicates each for 60 ***,32 fish were selected,divided into nor-moxia(18 fish)and hypoxia(18 fish)groups,and subjected to hypoxia stress for 96 *** CUR can attenuate histopathological damage caused by coming to OTA and hypoxia by reducing vacu-olation and nuclear *** alleviation of this damage was associated with the attenuation of apoptosis in the mitochondrial pathway by decreasing the expression of the pro-apoptotic proteins Caspase 3,8,9,Bax,and Apaf1 while increasing the expression of the anti-apoptotic protein Bcl-2,and attenuation of endoplasmic reticulum stress(ERS)by reducing Grp78 expression and chop *** may be attributed to the fact that the addi-tion of CUR increased the levels of catalase(CAT)and glutathione reductase(GSH),increased antioxidant capacity,and ensured the proper functioning of respiratory chain complexes I and II,which in turn reduced the high produc-tion of reactive oxygen species(ROS),thus alleviating apoptosis and *** In conclusion,our data demonstrate the effectiveness of CUR in attenuating liver injury caused by the combination of OTA and *** study confirms the feasibility and efficacy of adding natural products to mitigate toxic damage to aquatic animals.
