Abstract

The integration patterns of human papillomavirus (HPV) type 16 in the cellular DNA of six cervical carcinoma samples were analyzed by the Southern blot procedure. None of the HPV integrants retained the entire viral genome. Double HPV integration was found in one case while all other cases were single integrants. In some samples, internal deletion and selective amplification of the viral sequences were observed. On integration, the E2 open reading frame (ORF) was invariably lost but the E6/E7 ORFs and the long control region of the HPV-16 genome were retained in all seven integrations analyzed and may play a role in cellular transformation and/or maintainence of the transformed phenotype.

      E6 and E7 genes products have shown to be primarily responsible for the cellular transformation process (Takebe et al., 1987; Cripe et al., 1987; Vousden et al., 1988; Hakura et al., 1989). It has been proposed that the integration of HPV into the host genome occurs following a break in the E2 gene, which has been described as the main repressor of the expression of the E6 and E7 oncogenes (Choo et al., 1987b; zur Hausen, 2009). This break results in the loss of repression of these oncogenes, whose proteins interfere with the function of cellular proteins p53 and pRb, respectively.
