1、华中农业大学硕士学位论文GLP--1(7--36)CF3T3--L1细胞增殖和分化影响机制的探讨姓名:陈放申请学位级别:硕士专业:基础兽医学指导教师:龙良启;赵京杨201206GLP-1(7-36)对3T3-LI细胞增殖和分化影响机制的探讨摘要胰高血糖素样肽一1(GLP.1)是由直肠,远端回肠和结肠黏膜L细胞合成和分泌的一种多肽类激素。GLP.1具有改善胰岛素抵抗、降血糖和减少体重功能,使其成为治疗肥胖和糖尿病的新靶点。本课题研究旨在探讨胰高血糖素样肽.1[GLP.1(7.36)1对3T3.L1细胞的分化增殖及其相关基因表达的影响
2、。本试验通过研究GLP.1对3T3.L1细胞增殖分化的影响,探讨了增殖分化的剂量效应和时间效应,并分析了GLP.1对3T3.L1细胞周期的影响,采用QPC剐茳一步研究了GLP—l对3T3一L1增殖分化相关基因表达的影响。试验结果如下:1.GLP一1(10一M)gk理3T3.L14天能够显著事]]$1J3T3.L1前脂肪细胞的增殖(P<0.05):2.GLP.1(10’7M)能够显著影响3T3.L1前脂肪细胞的细胞周期(尸<0.05);3.GLP一1(10。7M)显著下调增殖相关基因P13K、P38和PKC‘的表达(P<0.01):
