摘要:

目的 探讨Fas基因mRNA及蛋白表达水平与人口腔鳞状细胞癌细胞凋亡的关系。方法 应用Northern 杂交、双参数流式术(TUNEL法)检测人口腔鳞状细胞癌中Fas mRNA及蛋白的表达,鳞癌细胞的细胞周期与凋亡水平。结果 5例正常口腔黏膜标本中均有Fas mRNA及蛋白的表达。在口腔鳞癌组织中,Fas mRNA及蛋白的表达与口腔鳞癌组织病理学分级有关(P<0·005),与口腔鳞癌组织分化程度和凋亡指数呈正相关。结论 口腔鳞癌中 Fas基因的表达与组织病理学分级及细胞凋亡之间关系密切。

Abstract:

Objective To investigate the relationship of Fas mRNA and protein expression and apoptosis in human oral squa- mous cell carcinoma.Methods Northern blot and flow cytometry (TUNELmethod) were used to detectthe expression of FasmR- NA and Fas protein, cell cycle and apoptotic level in oral squamous cell carcinoma. The relationship between Fas gene expression and OSCC apoptosis was analyzed statistically.Results Fas mRNA and protein could be detected in all five normal oral mucosa specimens. There was positive correlation between expression of Fas mRNA/protein and cell differentiation as well as apoptosis in OSCC(P<0.005).Conclusion The expression of Fas genewas highly correlatedwiththe differentiation and apoptosis in OSCC.
