目的探讨细胞增殖抑制基因(HSG/Mfn2)、p21WAF1蛋白在非小细胞肺癌中的表达及相关性。方法采用免疫组化sP法检测92例非小细胞肺癌中HSG/Mfn2、p21WAF1蛋白的表达。结果HSG/Mfn2在肺鳞癌、腺癌、非癌肺组织中吸光度值分别为15.06±2.73、12.21±2.96、10.36±3.60,差异有统计学意义(P〈0.05),并与肺癌分化程度有关。p21WAF1蛋白在肺鳞癌、腺癌、非癌肺组织中吸光度值分别为3.16±0.98、3、44±0.22、0.06±0.32,肺鳞癌和腺癌组织与非癌组织比较差异均有统计学意义(均P〈0.05),与分化程度、淋巴结转移有关。结论HSG/Mfn2,p21WAF1蛋白与肺癌发生、发展密切相关。二者在肺癌组织中的表达呈正相关:
Objective To investigate the expression of hyperplasia suppressor gene ( HSG)/mitofusin 2 (Mfn2) and P21 WAF1 in non-small cell lung cancer(NSCLC) . Methods The expression of( HSG/Mfn2 ) and P21 WAF1 was detected in 92 cases of NSCLC samples by immunohistochemistry( SP), Results The absorptance value of the expression of HSG/Mfn2 in squamous cell carcinoma, adenocarcinoma, and non-cancer tissue were 15.06 ± 2.73,12.21 ± 2.96 and 10.36 ± 3.60,respectively ( P 〈 0.05 ) , and they were associated with tumor differentiation. The absorptance value of the expression of P21WAF1 in squamous cell carcinoma,adenocarcinoma,and non-cancer tissue were 3.16 ±0.98,3.44 ±0.22,0, 06 ±0.32. The expression of P21 WAF1 in squamous cell carcinoma and adenocarcinoma was higher than that in non-cancer tissue ( P 〈 0.05 ) , and was closely associated with tumor differentiation and lymph node metastasis. Conclusion HSG/Mfn2,P21WAF1 is closely related to the pathogenesis and development of lung cancer . There is positive correlation between the HSG/Mfn2 and P21WAFI in lung cancer.
