[Methods] Immunohistochemical method was used to detect the expression of Med 19 protein in tongue cancer tissue and paracancerous tissue. [Results]The expression of Med19 protein in tongue cancer tissue was higher than paracancerous tissue and normal tissue. The expression of Med 19 protein was related to the tumor lymph node metastasis. However,there was no significant difference in sex,age,Tumor Node Metastasis( TNM),and differentiation degree. [Conclusions] Med 19 protein participates in incidence and development of tongue cancer and may become diagnostic indicator and therapeutic target for tongue cancer.展开更多
目的通过检测Med19在舌癌组织表达的基础上,探讨Med19表达下调对Tca8113细胞增殖的影响。方法应用免疫组织化学染色方法检测Med19在舌鳞癌组织及舌乳头状瘤组织中的表达,分析Med19的表达分布及表达水平;构建Med19 si RNA并转染人舌鳞癌...目的通过检测Med19在舌癌组织表达的基础上,探讨Med19表达下调对Tca8113细胞增殖的影响。方法应用免疫组织化学染色方法检测Med19在舌鳞癌组织及舌乳头状瘤组织中的表达,分析Med19的表达分布及表达水平;构建Med19 si RNA并转染人舌鳞癌细胞Tca8113,应用MTT检测细胞增殖的改变。结果免疫组织化学染色结果显示Med19在舌癌组织中高表达;建立si RNA-Med19重组慢病毒载体并转染Tca8113,MTT结果显示Med19下调可以抑制细胞增殖。结论 Med19在舌鳞状细胞癌中高表达;通过si RNA-Med19慢病毒载体转染Tca8113细胞可以抑制细胞增殖,为后续体内实验奠定坚实的基础。展开更多
