目的探讨LAMA4调控TGF-β1/SMAD Western blot检测LAMA4在肝癌细胞Huh7和HepG2及正常肝细胞L02中的表达;MMT法和流式细胞技术检测LAMA4和TGF-β1/SMAD信号传导途径对Huh7细胞增殖和凋亡的影响;RT-qPCR和Western blot检测LAMA4对TGF-β1/...目的探讨LAMA4调控TGF-β1/SMAD Western blot检测LAMA4在肝癌细胞Huh7和HepG2及正常肝细胞L02中的表达;MMT法和流式细胞技术检测LAMA4和TGF-β1/SMAD信号传导途径对Huh7细胞增殖和凋亡的影响;RT-qPCR和Western blot检测LAMA4对TGF-β1/SMAD信号转导通路和细胞免疫因子TNF-α、IFN-γ、TGF-β1的影响。结果 RT-qPCR和Western blot检测结果显示:LAMA4在肝癌细胞Huh7和HepG2中mRNA表达显著上调;LAMA4在肝癌细胞Huh7和HepG2中蛋白表达显著上调;沉默LAMA4使TGF-β1和SMAD4表达显著上调,SMAD6、IFN-γ和TNF-α的含量显著降低,过表达LAMA4则结果相反;MMT法和流式细胞技术检测结果显示:敲低LAMA4可使Huh7细胞活力下降,细胞凋亡率增加,而过表达LAMA4则结果相反;Ly364947干扰TGF-β1/SMAD信号传导路径后,Huh7细胞的活力增加,细胞凋亡率显著下降,IFN-γ和TNF-α的含量显著升高,TGF-β1显著降低,且Ly364947可部分逆转沉默LAMA4对肝癌细胞Huh7的免疫逃逸因子和凋亡的调控作用。结论 LAMA4可通过调控TGF-β1/SMAD信号传导途径影响肝癌细胞免疫逃逸和凋亡。展开更多

China is the most-frequently studied nation in Asian mass communication research. The past the 14th Dalai Lama＇s image studies mainly focus on Western mainstream newspapers, due to the fact that these newspapers are well established and frequently read by policy-makers and other influential individuals. In recent years, ＂Social media＂ has become a new buzzword. Social media platforms like Facebook, Twitter and Weibo etc. have made a considerable impact on contemporary life. What is the 14th Dalai Lama＇s image as it is represented via Western social media？ Do Western social media publish the 14th Dalai Lama＇s different contents, from a different perspective, or in a different way from that of the standard Western mainstream news outlets？ Are there any differences between the image of the 14th Dalai Lama on Western social media and on mainstream media？ What are differences between the image of the 14th Dalai Lama on Western and Chinese social media when discussing the same event or topic？ The research aims to answer these questions the 14th Dalai Lama; Western social media; Chinese social media.展开更多
