Presence of human papillomavirus type‐16 and type‐18 DNA sequences and their expression in cervical cancers and cell lines from japanese patients

Abstract

Southern blot analyses of surgical specimens of cervical carcinoma from Japanese patients showed that 3/9 samples contained human papillomavirus (HPV) type‐16 DNA sequences, and 2 contained HPV type‐18 DNA sequences. By Northern blot analyses, RNA transcripts of HPV DNA sequences were demon‐trated in some of the tissues containing HPV type‐16 or HPV type‐18 DNA sequences. Two cell lines established from cervical cancers of Japanese patients also contained HPV type‐18 genomes and these cell lines contained HPV type‐18 transcripts. Two other cervical cancer cell lines from a Japanese patient were found to contain HPV type‐16 DNA sequences and their RNA transcripts. Copyright © 1986 Wiley‐Liss, Inc., A Wiley Company
