No significant pathological symptoms were observed in the liver of goose after overfeeding, suggesting that a specific protection mechanism exists in goose liver. Previous studies have shown that mitochondria may participate in the formation of goose fatty liver by improving its energy metabolism and the production of precursor metabolites. To further understand the role of mitochondria in the formation of goose fatty liver, the present study investigated the changes of mitochondrial function, anti-oxidant capacity, and apoptosis in goose fatty liver. There were found that the level of mitochondrial membrane potential was increased, no apoptosis was observed and anti-oxidant capacity was improved in goose fatty liver, no apoptosis was observed and anti-oxidant genes expressions were increased in goose primary hepatocytes after 40 mM glucose treatment. Our findings imply that apoptosis is inhibited by glucose-induced enhanced anti-oxidant activity in goose fatty liver. Our study not only contributes to revealing the protective mechanism in goose fatty liver but also providing new references for the study of nonalcoholic fatty liver in mammals.
