title: Molecular cloning and characterization of the DNA of a new human papillomavirus (HPV 30) from a laryngeal carcinoma.
abstract: DNA from a human laryngeal carcinoma was molecularly cloned in Lambda L47. The gene library was screened for human papillomavirus (HPV)-related sequences by hybridization analysis with 32P-labelled HPV 16 DNA at conditions of low stringency (Tm -40 degrees C). One of the clones (4-5) with an insert of 7.8 kb showed cross-hybridization with most of the known HPV types (Tm -40 degrees C), and with several of them even under more stringent conditions (Tm -30 degrees C). No signal was detected under high-stringency conditions (Tm -20 degrees C). The co-linear alignment of clone 4-5 with HPV 16 DNA could be demonstrated by hybridization experiments and also by partial DNA sequence analysis. We conclude that clone 4-5 represents a new HPV type tentatively designated HPV 30. HPV 30 DNA was also detected in 2 genital lesions but not in 41 laryngeal carcinomas analyzed so far. Its presence in other tumor DNA is now under investigation.
