摘要 目的探讨人乳头瘤病毒(HPV)和促癌物在肿瘤诱发过程中的协同作用。方法研究选择与恶性肿瘤关系密切的癌基因和抑癌基因,利用免疫组化、Southem Blot和半定量RNA斑点杂交的方法,研究在HPV18E6E7和促癌物佛波酯(TPA)的协同作用下,这些基因在细胞内的表达。结果HPVE6E7和TPA的协同作用可以引起细胞内癌基因c-myc的扩增4-8倍,c-erbB2的表达水平提高32-64倍,并导致抑癌基因p16的表达水平下降到正常水平的1/4.1/8。结论HPVE6E7和TPA的协同作用可以引起细胞内癌基因和抑癌基因表达水平异常,可能是细胞癌变的重要原因之一。 Objective To investigate the molecular mechanism of the synergistic effects of human papillomavirus(HPV) and phorbal esters(TPA) in cell transformation. Method The expression of oncogenes and anti-oncogenes in 293 cell line treated with HPV and TPA was studied by Southern Blot and RNA dot blot. Result It was found that the synergistic effect induced the amplification of c-myc (4-8 times), increased expressing level of c-erbB-2 (32-64 times) and decreased expressing level of p16( 1/4-1/8). Conclusion The above results show that the synergistic effect has an important role in development of carcinoma.
