摘要:
目的 探讨AMP活化蛋白激酶(AMPK)信号通路在C1q/肿瘤坏死因子相关蛋白3(CTRP3)调节3T3-L1脂肪细胞脂联素表达中的作用。方法 将3T3-L1脂肪细胞分为对照组、CTRP3(250 ?滋g/L)干预组及CTRP3(250 ?滋g/L)+ Compound C(10 ?滋mol/L 预处理1 h)干预组。以酶联免疫吸附法(ELISA)检测细胞培养上清中脂联素含量,实时定量PCR检测脂联素mRNA相对表达水平,Western印迹检测AMPK(thr172)蛋白相对表达量。结果 与对照组相比,CTRP3干预组脂联素mRNA表达及蛋白分泌分别增加53.0%(q =15.09,P<0.01)及63.3%(q =8.11,P<0.01),AMPK(thr172)表达增加43.0%(q =14.64,P<0.01);与CTRP3干预组相比,CTRP3+Compound C干预组AMPK(thr172)蛋白的表达降低57.3%(q =27.92,P<0.01),脂联素mRNA表达及蛋白分泌分别下降26.1%(q =11.39,P<0.01)及54.1%(q =11.31,P<0.01)。结论 AMPK信号通路参与了CTRP3对3T3-L1脂肪细胞脂联素表达的调控过程。
Abstract:
Objective To investigate the role of AMP activated protein kinase(AMPK) signal in the modulation of C1q/TNF related protein 3(CTRP3) on the expression of adiponectin in adipocytes.Methods  The 3T3-L1 adipocytes were divided into control group,CTRP3(250 ?滋g/L) intervention group and CTRP3(250 ?滋g/L)+ Compound C(10 ?滋mol/L pretreated for 1 h) intervention group.The content of adiponectin in supernatant was detected by enzyme linked immunosorbent assay.The relative expression of adiponectin mRNA was detected by real-time polymerase chain reaction.The relative expression of AMPK(thr172) was detected by Western blot.Results Compared with control group, expression of adiponectin mRNA and protein increased 53.0% (q =15.09,P<0.01) and 63.3% (q =8.11,P<0.01) respectively, the expression of AMPK(thr172) increased 43.0% (q =14.64,P<0.01) in CTRP3 intervention group.Compared with CTRP3 intervention group,the expression of AMPK(thr172) in CTRP3+ Compound C intervention group decreased 57.3% (q =27.92,P<0.01),expression of adiponectin mRNA and protein decreased 26.1%(q =11.39,P<0.01) and 54.1% (q =11.31,P<0.01) respectively.Conclusion AMPK signal participates in the modulation of CTRP3 on the expression of adiponectin in 3T3-L1 adipocytes.
