摘要
目的:探讨p16基因在由乙型肝炎病毒基因整合引起的小鼠肝细胞癌发生发展中的表达变化规律。方法:以乙肝病毒表面抗原基因(HBsAg)及X基因(HBx)定位整合转基因小鼠及对照小鼠的肝脏组织为标本,利用North-ern印迹、Western印迹及免疫组织化学检测p16在乙肝病毒基因定位整合转基因小鼠肝脏正常组织与肿瘤组织中的差异表达。结果:p16主要在小鼠胚胎期的肝脏中表达,在新生小鼠和成年小鼠的肝脏组织中几乎检测不到其表达;在HBsAg转基因小鼠和HBx转基因小鼠的肝脏肿瘤中,p16的表达明显升高。结论:p16基因在HBsAg或HBx诱导的肝细胞癌发生过程中被重新激活,也许发挥重要的作用。
Objective: To study the expression of p16 in the process of HBV-related hepatocarcinogenesis.Methods: The expression of p16 in liver tissues and tumors of HBsAg and HBx transgenic mice and wild type control mice was evaluated by Northern blot,Western blot and immunohistochemical analysis.Results: p16 expression was detected in fetal liver,but barely detected in liver of control mice after birth.The expression of p16 was up-regulated in liver tumors of HBsAg and HBx transgenic mice when compared with adjacent normal tissues.Conclusion: p16 was reactivated,and might have important function during the process of HBV-related hepatocarcinogenesis.
