Persistent infections with human papillomaviruses type 18 can result in the development of cervical cancer. HPV18 genomes persist extrachromosomally in low-grade and precancerous lesions but are always integrated in cervical cancers, and this might contribute to the progression of HPV18-induced lesions. To address whether integration induces additional changes in host cells, several keratinocyte lines with wild type and replication-deficient E1 mutant HPV18 (E1C-TTL) genomes were analyzed with high density oligonucleotide arrays. In comparison to normal keratinocytes, wild type and integrated E1C-TTL HPV18 genomes deregulate the expression of 280 annotated genes. However, the comparison of wild type with E1C-TTL cell lines did not reveal any significant differences, indicating that neither the loss of E1 nor viral integration induces additional gene expression changes in low passage HPV18-positive keratinocytes. Half of the deregulated genes have been described as targets of the p16/Rb/E2F, p53, interferon or NFkappaB pathways consistent with the functions ascribed to the viral E6 and E7 oncoproteins, but the other half can currently not be ascribed to certain pathways.
