mRNA sequencing was performed on 10 oropharyngeal cancer cell lines (5 HPV-positive and 5 HPV-negative cell lines) for this project. Two cell lines (CU-OP-17 and CU-OP-20) were newly derived from HPV-negative and HPV-positive tonsil cancers, respectively (described in " Sensitivity of human papillomavirus-positive and -negative oropharyngeal cancer cell lines to ionizing irradiation" by Holzhauser et al.   This study was performed with the goal to identify differences in gene expression between irradiated and non-irradiated cell line samples. Additionally, the aim was to identify possible changes in genes, involved in DNA repair or DNA damage response of the HPV-positive and HPV-negative cell lines.  The data published showed an increase of HPV integration sites after irradiation. Additionally, all HPV-positive cell lines in this study showed expression of HPV encoded genes. However, no direct correlation of changes or expression of DNA repair genes was identified. SOURCE: Peter Giles (GilesPJ@Cardiff.ac.uk) -  Cardiff University
