摘要: 本试验旨在探讨牛磺胆酸(taurocholate acid,TCA)对小鼠腹腔巨噬细胞刺激性G蛋白α(Gsα)基因表达的影响,为阐明TCA对小鼠腹腔巨噬细胞的作用机制提供线索。采用荧光定量PCR技术检测TCA对小鼠腹腔巨噬细胞Gsα mRNA表达的影响。试验结果显示,高(15 μg/mL)、中(1.5 μg/mL)和低剂量(0.15 μg/mL)的TCA作用组小鼠腹腔巨噬细胞Gsα mRNA的表达均显著高于对照组和LPS刺激组(P<0.05)。结果表明,TCA能显著促进小鼠腹腔巨噬细胞Gsα mRNA的表达。

Abstract: The assay was aimed to explore the effect of taurocholate acid (TCA) on Gsα expression in peritoneal macrophage in mouses, and provide clues for explaining the function mechanism of TCA on mouse peritoneal macrophages. The peritoneal macrophages of mouse were isolated and cultured. The effect of TCA on the expression of Gsα mRNA was examined quantitatively by Real-time fluorescent quantitative PCR. TCA(15,1.5 and 0.15 μg/mL) decreased significantly the expression of Gsα mRNA in peritoneal macrophage in mouses (P<0.05), compared with that in control group and LPS group. The results showed that TCA could significantly promote the expression of Gsα mRNA in peritoneal macrophage in mouses.

Key words: taurocholate acid; Gsα; Real-time fluorescent quantitative PCR; peritoneal macrophage
