Title: Detection of human papillomavirus DNA in genital warts, cervical dysplasias and neoplasias. Author: Tomita Y, Kubota K, Kasai T, Sekiya S, Takamizawa H, Simizu B. Journal: Intervirology; 1986; 25(3):151-7. PubMed ID: 3015831. Abstract: Biopsies from human genital lesions in Japan (108 samples), including condyloma acuminata, squamous metaplasia, dysplasia, and cervical cancer, were screened for the presence of human papillomavirus (HPV) 6-, 11-, 16-, and 18-related DNAs by spot hybridization and Southern blot hybridization under stringent conditions. By spot hybridization, HPV 6/11-related DNA was found in 92.9% (13/14) of condyloma acuminata and in 6.7% (1/15) of cervical cancer biopsies. HPV 16/18-related DNA was found in 37.7% (5/14) of cervical cancer biopsies and was exclusively associated with invasive squamous cell cancer, 66.7% (8/12), and with cervical carcinoma in situ, 50% (9/18). Some sample DNAs were further characterized by restriction enzyme digestion followed by Southern blot analysis, and we confirmed the presence of HPV-specific DNA fragments and mixed infection with both HPV 6/11- and HPV 16/18-related HPVs in one lesion.[Abstract] [Full Text] [Related] [New Search]
