A recurrent human papillomavirus integration site at chromosome region 12q14-q15 in SW756 and SK-v cell lines derived from genital tumors.
The SW756 cell line, derived from an invasive cancer of the uterine cervix, harbours integrated human papillomavirus (HPV) 18 DNA sequences which have been located in chromosome band 12q13. By in situ hybridization experiments with tritiated and digoxigenin-labelled HPV18 probes on R-banded chromosomes, we now localize the integrated viral sequences in 12q14-q15. Interestingly, we have previously localized integrated HPV16 sequences in the same chromosomal region in SK-v cells, derived from a pre-invasive vulvar neoplasia. The chromosomal region 12q14-q15 could thus correspond to a preferential site for the integration of HPV DNA in genital tumors.
