Abstract: The purpose of this study was to investigate the effect of resveratrol on the injury of porcine small intestinal epithelial cells(IPEC-J2 cells)induced by zearalenone(Zen). The experimental groups were: Group C(control group), group Z(25 µg/mL Zen), group ZR1(25 µg/mL Zen+10 µmol/L resveratrol), group ZR2(25 µg/mL Zen+20 µmol/L resveratrol), group ZR3(25 µg/mL Zen+30 µmol/L resveratrol). The cell viability, the activity of lactate dehydrogenase(LDH), the level of antioxidant enzymes and the mRNA expression of apoptosis related genes such as caspase 3, caspase 9, Bcl-2 and Bax were measured. The results showed that the cell viability, SOD activity, T-AOC level and Bcl-2 gene mRNA expression level in group Z were significantly lower than those in group C(P<0.01). The cell viability, SOD activity, T-AOC level and Bcl-2 gene mRNA expression level in group ZR2 and ZR3 were significantly higher than those in group Z or group ZR1(P<0.01 or P<0.05). The LDH activity, MDA level, Capase-3, Capase-9 and Bax gene mRNA expression levels in group Z were significantly higher than those in group C(P<0.01). The LDH activity, MDA level, Capase-3, Capase-9 and Bax gene mRNA expression levels in group ZR2 and ZR3 were lower or significantly lower than those in group Z or group ZR1(P<0.01 or P<0.05). The LDH activity and Bax gene mRNA expression levels in ZR1 group were lower than those in group Z(P<0.01). The results indicated that resveratrol could alleviate the changes of cell viability, LDH activity, antioxidant function and apoptosis related gene mRNA expression of IPEC-J2 cells induced by Zen.

Key words: resveratrol, zearalenone, porcine intestinal epithelial cells, cell viability, lactate dehydrogenase activity, antioxidant function, apoptosis gene
