目的:探讨lncRNA H19在口腔黏膜下纤维性变(OSF)发生及癌变过程中的表达变化及其意义.方法:实时荧光定量PCR技术分别检测12例正常颊黏膜组织、33例OSF颊黏膜组织、31例伴OSF颊癌组织中的LncRNA H19的表达水平.结果:LncRNA H19在颊黏膜组织、OSF颊黏膜组织、伴OSF颊癌组织中的相对表达量分别为1.17±0.37、3.44±1.08、8.88±1.78,组间两两之间比较,P＜0.01.结论:LncRNA H19可能参与OSF的发生及癌变.%Objective:To study the significance of H19 gene in the progress from normal mucosa through oral submucous fibrosis (OSF) to carcinogenesis.Methods:Real-time fluorescent quantitative PCR technique was used to detect LncRNA H19 expression level in 12 cases of normal buccal mucosa tissue,33 cases of OSF buccal mucosa tissue and 31 cases of buccal carcinoma with OSF.Results:The relative expression levels of LncRNA H19 in normal buccal mucosa tissues,OSF buccal mucosa tissue and buccal carcinoma with OSF tissue were 1.17 ±0.37,3.44 ± 1.08 and 8.88 ± 1.78 respectively(between each 2 groups,P ＜ 0.01).Conclusion:H19 may involve the occurrence and canceration of OSF.
