摘要: 目的: 观察HPV-16 E6 和食管癌细胞核基质的关系,以探讨HPV 感染在食管癌变中的作用。方法:2 株食管癌细胞系,EC/ CUHK1 和EC/ CUHK2 ,用于本实验。PCR 扩增核基质相关的HPV-16 E6 亚基因片段,RT-PCR 和免疫细胞化学染色观察了E6 亚基因在癌细胞内的表达。结果: EC/ CUHK2 细胞的HPV-16 E6 亚基因片段存在于核基质相关DNA 中,E6 癌蛋白位于核基质组分内;而EC/ CUHK1 细胞的结果均为阴性。结论:HPV-16 E6 和核基质的相互作用有助于病毒导致的食管癌发生。

Abstract: Purpose : To explore the etiologic role of HPV infection in sophageal carcinoma , the association of HPV-16 E6 with the nuclear mat rix of carcinoma cells was investigated. Methods : Two esophageal carcinoma cell lines , EC/ CUHK1 and EC/ CUHK2 , were tested for HPV-16 E6 subgenic fragment by using polymerase chain reaction amplification of virus DNA associated nuclear matrix. RT-PCR and immunocytochemist ry were used to visualize the expression of E6 subgene in the cells. Results : The HPV-16 E6 subgenic fragment were found to be present in nuclear mat rix-associated DNA , E6 oncoprotein localized in the nucleus where it tightly associate with nuclear mat rix after sequential extraction in EC/ CUHK2 cells. This phenomenon was not detected , however , in EC/ CUHK1 cells. Conclusion : The interaction between HPV-16 E6 and nuclear mat rix may cont ribute to the viral induced carcinogenesis in esophageal carcinoma cell line EC/ CUHK2.

Key words: esophageal carcinoma, nuclear matrix, human papillomavirus
