Hedgehog信号通路效应蛋白在舌癌组织中的表达及意义
|
Abstract:
摘要 目的:探讨Hedgehog(HH)信号通路中效应蛋白Ptch、Smo和Gli1在舌癌、癌旁组织中的表达及意义。方法:采用免疫组织化学方法检测我院24例舌癌患者的病灶及癌旁组织中Ptch、Smo和Gli1的表达。结果:Ptch和Smo在舌癌组织中为高表达,与患者年龄、性别、烟酒习惯等不相关,而与组织学分级、临床分期有相关性,在组织学分级和临床分期越高的舌癌组织中表达越高。部分Ptch及Smo阳性表达的舌癌组织中,Gli1也呈阳性表达。结论:HH信号通路可通过Ptch和Smo的过度表达,有可能通过进一步激活转录因子Gli1及其他目的基因,与舌癌的发生及发展存在一定关系
