HPV-related methylation in Oropharyngeal squamous cell carcinomas (OPSCC)


ABSTRACT: Using MCIp, we enriched highly methylated DNA from a normal mucosa control and from three OPSCC patient subgroups regarding the HPV status: group A, DNA-RNA- (Tu1-Tu5); group B, DNA+RNA- (Tu6-Tu10); group C, DNA+RNA+ (Tu11-Tu15). 3 groups of tumor biopsies, 5 samples each regarding HPV status: DNA-RNA-, DNA+RNA-, DNA+RNA+ and a control sample (normal mucosa from healthy individual): 15 tumor samples/ 1 control sample

High-risk types of human papilloma virus (HPV) are increasingly associated with oropharyngeal squamous cell carcinoma (OPSCC). Strikingly, patients with HPV-positive OPSCC are highly curable with ionizing radiation and have better survival compared with HPV-negative patients, but the underlying molecular mechanisms remain poorly understood. We applied an array-based approach to monitor global changes in CpG island hypermethylation between HPV-negative and HPV-positive OPSCCs and identified a spe  ...[more]
