摘　　要：肿瘤的发生、发展受多种基因调控。脆性组氨酸三联体基因(FHIT)是近几年发现的抑癌基因,目前大量研究证实,脆性组氨酸三联体基因定位于3p14.2,其抑癌作用可能与调控细胞周期、诱导细胞凋亡、二腺苷三磷酸水解酶、微管蛋白、泛素结合酶等有关。文章就FHIT基因的结构、抑制肿瘤的作用、机制及其在喉癌中缺失及异常的相关研究近况予以综述。The occurrence and progress of tumor are regulated by many genes. The fragile histidine triad gene （FHIT） is a new-found gene which can suppress the progressive growth of tumor recently. It has identified at chromosome 3p14.2 by positional cloning. The mechanisms for inactivating the gene have been revealed to deletions,cell cycle retardation hydrolysis of 5＇ ,5＂-P1, P3-triphosphate hydrolase （Ap3A） , tubulin, and ubiquitin conjugase. This article will review the structure of FHIT gene and summarize its function and mechanism in tumor suppression, and its deletion and abnormal expression in laryngeal carcinoma.
