摘要 目的研究游离脂肪酸受体4/G蛋白偶联受体120(FFAR4/GPR120)激动剂TUG891对脂肪细胞的细胞因子mRNA水平的影响。方法 3T3-F442A细胞在含100 m L/L胎牛血清(FBS)的完全DMEM培养基中培养至接触抑制2 d后,换至诱导分化培养基继续培养2 d;随后,用含100 m L/L FBS、0. 24 IU/m L胰岛素的DMEM维持培养基培养2 d;最后,在含100 m L/L FBS的完全DMEM培养基培养6~8 d。当80%以上细胞出现脂滴沉积后,细胞分为对照组和10μmol/L FFAR4激动剂TUG891处理组。处理12 h后,应用反转录PCR检测3T3-F442A脂肪细胞内白细胞介素1(IL-1)、IL-6、IL-12、IL-8、IL-10、IL-15、肿瘤坏死因子α(TNF-α)和单核细胞趋化蛋白1(MCP-1)、抵抗素(resistin)的mRNA水平。结果 3T3-F442A细胞经诱导后分化为脂肪细胞。与对照组相比,TUG891处理组3T3-F442A脂肪细胞的IL-1、IL-6、IL-12、TNF-α和MCP-1的mRNA水平显著下降,IL-8、IL-10、IL-15和resistin的mRNA水平变化不明显。结论激活FFAR4/GPR120抑制脂肪细胞的细胞因子IL-1、IL-6、IL-12、TNF-α和MCP-1转录。
