Objective To observe the influence of gene transfection of inducible nitric oxide synthase to the transplanted human laryngeal squamous carcinoma in nude mice, to investigate the expression and the correlayion of iNOS and p53, and to proke into the possible apoptosis mechanism. Methods Transfect the gene of iNOS to Hep-2 human laryngeal cancer cell, sieve out positive clone cell and amplify.

目的 观察诱生型一氧化氮合酶(inducible nitric oxide synthase， iNOS)基因转染对人喉鳞癌细胞裸鼠移植瘤生长的影响，研究在体人喉鳞癌细胞中iNOS与突变型p53基因的表达，探讨二者的相关性及促进肿瘤细胞凋亡的机制。
