人乳头瘤病毒6型(HPV 6)DNA在外阴浸润性鳞状细胞癌提取的DNA中检测到游离形式。对命名为HPV 6-T70的病毒DNA进行分子克隆。HPV 6-T70基因组的限制性分析显示,在相对于从良性生殖器疣(E. M.德维利尔斯湖Gissmann和H. zur豪森,1981,病毒学杂志,40,932-935)。然而,上游调控区的序列分析确定了跨越核苷酸7292-7400的富含嘌呤-胸苷的区域中的几个改变。在7323位插入24个碱基代表核苷酸7300-7323的精确串联重复。在7350位的第二个58 bp插入与紧邻的HPV 6序列(核苷酸7303-7356)具有84%的位置同一性,并且也与在HPV-6vc中在7348位发现的74-bp插入相似,HPV-6vc克隆自外阴的侵袭性疣状癌(R. F. Rando,D. E. Groff,J. G. Chirikjian和W. D.兰开斯特,1986,J.Virol.57,353-356)。在58-bp插入之后立即缺失49个碱基(核苷酸7351-7399)。克隆的HPV 6-T70 DNA可诱导NIH 3 T3细胞发生形态学转化。
Human papillomavirus type 6 (HPV 6) DNA was detected in an episomal form in DNA extracted from an invasive squamous carcinoma of the vulva. The viral DNA, designated HPV6-T70, was molecularly cloned. Restriction analysis of the HPV6-T70 genome revealed an insertion of ≈35 by in the 5′ portion of the upstream regulatory region relative to the prototype HPV 6b genome, cloned from a benign genital wart (E.-M. de Villiers, L. Gissmann, and H. zur Hausen, 1981,J. Virol.40, 932–935). However, sequence analysis of the upstream regulatory region identified several alterations in the purine-thymidine-rich region spanning nucleotides 7292–7400. One insertion of 24 by at position 7323 represented an exact tandem duplication of nucleotides 7300–7323. A second insertion of 58 by at position 7350 had 84% positional identity to immediately adjacent HPV 6 sequences (nucleotides 7303–7356) and was also similar to the 74-bp insertion found at position 7348 in HPV-6vc, cloned from an invasive verrucous carcinoma of the vulva (R. F. Rando, D. E. Groff, J. G. Chirikjian, and W. D. Lancaster, 1986,J. Virol.57, 353–356). A deletion of 49 by (nucleotides 7351–7399) immediately followed the 58-bp insertion. The cloned HPV6-T70 DNA induced the morphological transformation of NIH 3T3 cells.
