Abstract:

The study was conducted to investigate the effect of folic acid on metabolism of chicken primary hepatocytes, aiming to provide a reference for exploring regulation mechanism of folic acid on hepatic metabolism and also provide theoretical and scientific basis for its application in poultry. New-born chickens were used for separating primary liver cells. When the confluence reached to about 80%, hepatocytes were exposed to treatment medium. The control group and folic acid addition group were contained in the study. There were 6 replicates for each group. After 12 h treatment, cells were collected to detect triglyceride, NEFA and cholesterols contents. Metabolomics analysis was carried out by GC-MS method. The OPLS-DA model was established to identify differential metabolites, and pathways enriched based on differential metabolites were analyzed through KEGG system. The results showed that folic acid significantly decreased triglyceride and cholesterol contents in hepatocytes compared with the control group (P<0.05). NEFA level was higher in folic acid addition group (P<0.05). Twenty three up-regulation and 9 down-regulation metabolites were found between two groups, which mainly included amino acid, small molecule sugar and acid. Thirty one pathways were enriched based on differential metabolites containing amino acid metabolism, carbohydrate metabolism, lipid metabolism, and so on. The results indicated that folic acid could promote lipid hydrolysis in chicken primary hepatocytes, and was involved in regulating sugar, lipid and amino acid metabolism, which would provide a reference for exploring regulatory mechanism of folic acid on hepatic metabolism in future.
