目的:研究ras同系物(ras homologue,Rho)C蛋白及其调节蛋白Rho二磷酸鸟苷解离抑制因子(Rho guanosine diphosphate dissociation inhibitor, RhoGDI)-β和-γ在肺癌细胞中的表达情况.方法:应用Western印迹法和RT-PCR检测人正常支气管上皮细胞和不同人肺癌细胞系中RhoC、RhoGDIβ和RhoGDIγ蛋白及mRNA的表达.结果:RhoC、RhoGDIβ和RhoGDIγ的蛋白及mRNA在人肺腺癌细胞系、人肺巨细胞癌细胞系(高和低侵袭力亚型)和人支气管上皮细胞系中均有表达.3种肺癌细胞系中RhoC、RhoGDIβ和RhoGDIγ的表达均明显高于人支气管上皮细胞系.高侵袭力人肺巨细胞癌细胞系BE1中RhoC和RhoGDIγ的表达均明显高于低侵袭力人肺巨细胞癌细胞系LH7.低侵袭力人肺巨细胞癌细胞系LH7中RhoGDIβ的表达高于高侵袭力人肺巨细胞癌细胞系BE1.结论:高侵袭力人肺巨细胞癌细胞BE1中RhoC和RhoGDIγ的表达较高,低侵袭力人肺巨细胞癌细胞系LH7中RhoGDIβ的表达较高.
目的:研究ras同繫物(ras homologue,Rho)C蛋白及其調節蛋白Rho二燐痠鳥苷解離抑製因子(Rho guanosine diphosphate dissociation inhibitor, RhoGDI)-β和-γ在肺癌細胞中的錶達情況.方法:應用Western印跡法和RT-PCR檢測人正常支氣管上皮細胞和不同人肺癌細胞繫中RhoC、RhoGDIβ和RhoGDIγ蛋白及mRNA的錶達.結果:RhoC、RhoGDIβ和RhoGDIγ的蛋白及mRNA在人肺腺癌細胞繫、人肺巨細胞癌細胞繫(高和低侵襲力亞型)和人支氣管上皮細胞繫中均有錶達.3種肺癌細胞繫中RhoC、RhoGDIβ和RhoGDIγ的錶達均明顯高于人支氣管上皮細胞繫.高侵襲力人肺巨細胞癌細胞繫BE1中RhoC和RhoGDIγ的錶達均明顯高于低侵襲力人肺巨細胞癌細胞繫LH7.低侵襲力人肺巨細胞癌細胞繫LH7中RhoGDIβ的錶達高于高侵襲力人肺巨細胞癌細胞繫BE1.結論:高侵襲力人肺巨細胞癌細胞BE1中RhoC和RhoGDIγ的錶達較高,低侵襲力人肺巨細胞癌細胞繫LH7中RhoGDIβ的錶達較高.
