摘要: 取单层培养72 h生长良好的犊牛肝细胞,采用单因素重复试验,分别添加0、50、100、200、500、1000 pg/ml的羊体外合成神经肽Y(neuropeptide Y,NPY),每个处理3个重复(每重复2孔),再培养12 h后分别提取RNA和制备细胞上清液。应用荧光定量PCR方法检测外源NPY 对肝细胞糖异生关键酶丙酮酸羧化酶(pyruvate carboxylase,PC)基因表达的影响,同时用比色法检测其对肝细胞PC活性的影响。结果表明,一定浓度的NPY显著促进了肝细胞PC mRNA表达,增强了PC活性。

Abstract: A single factor duplicate test was designed to investigate whether neuropeptide Y affects the expression of pyruvate carboxylase (PC) mRNA and the activity of PC in vitro culture bovine hepatocyte. Neuropeptide Y was added to the media with 0,50,100,200,500,1000 pg/ml. Abuundance of PC mRNA in vitro culture bovine hepatocyte cultured for 12 hours after Neuropeptide Y was added was determined by real-time fluorescence quantitative RT-PCR, and activity of PC was determined by colourimetry. The results showed that the neuropeptide Y could stimulate the expression of PC mRNA was and the activity of PC in vitro culture bovine hepatocyte.

Key words: neuropeptide Y; hepatocyte; pyruvate carboxylase
