JF Journal of General Virology, VO 78 IS 5 SP 1095 OP 1101 DO https://doi.org/10.1099/0022-1317-78-5-1095 PB Microbiology Society, SN 1465-2099, AB We have matched a PCR assay which detects disruptions in the E2 reading frame of human papillomavirus type 16, with RNA in situ hybridization patterns and shown that in 15 out of 16 cervical intraepithelial neoplastic (CIN) III lesions and in 19 out of 19 tumours, the E2 gene is disrupted with no detectable E2 transcripts. Varying levels of E6–E7 transcripts are detected in CIN III lesions, with stronger signals in tumours. The cytokeratin profile of most tumours: cytokeratin 10-, 14- and 19-positive and 4-, 13- and 18negative, is also detected in CIN III lesions. The changes in levels of α2, β1 and β4 integrins, CD44 and E-cadherin occur during the evolution of high-grade CIN lesions. Increases in the levels of expression of CD44 and E6-E7 transcripts, coupled with changes in the cellular localization of the Notch protein, define the transition from CIN III lesions to tumours., UL https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-78-5-1095
