摘要:

本研究以鸡原代肝细胞为试验材料,探讨鸡L-BABP基因对脂类代谢相关基因及生化指标(总胆固醇、甘油三酯、低密度脂蛋白和高密脂蛋白)的影响。利用RNAi和过表达技术下调和上调该基因的表达,分别在干扰和过表达24、36、48、60和72 h时检测鸡肝细胞中脂类代谢相关基因的表达量变化及细胞培养基中脂类代谢相关生化指标的变化。结果显示,鸡L-BABP基因表达量的变化显著或极显著影响APOBAPOAΙPERILIPIN基因表达,且显著地改变细胞培养基中的甘油三酯和总胆固醇的含量。基于以上结果,本研究推测鸡肝细胞中L-BABP基因可能参与禽类脂肪沉积、总胆固醇代谢和脂解过程。

Abstract:

This study was designed to investigate the role of L-BABP gene in lipid metabolism of hepatocytes and the effect of L-BABP gene on the genes related to lipid metabolism in chicken.L-BABP gene expression was downregulated by siRNA interference and upregulated via overexpression plasmids method.The genes expression level in chicken hepatocytes were detected at 24,36,48,60 and 72 h after transfection with the siRNAs and overexpression plasmids of L-BABP.The results showed that APOAΙAPOBPERILIPIN gene expression levels,the amount of cholesterol and triglyceride in the medium are significantly affected by L-BABP gene expression changes.Therefore,L-BABP may involve in fat deposition,metabolism of total cholesterol and the process of lipolysis lipid metabolism.
