| Outline of Final Research Achievements |
In this project, it was demonstrated that long control region (LCR) of HPV-16 in HPV-16 positive head and neck cancer (HNC) is often hypomethylated, and hypermethylation status of E2-binding Sites of HPV-16 frequently contributes to carcinogenesis in HNC. The extent of HPV-DNA methylation is not associated to the prognosis of HNC. Compared to HPV-DNA positive HNC, the higher level of SMG-1 mRNA expression in HPV-DNA negative HNC was observed. Lower SMG-1 mRNA expression may be associated with radiotherapy sensitivity in HNC. In addition, our findings revealed that the LCR of HPV-6 is frequently hypomethylated in laryngeal papilloma. Seven papers in English have published during 3 years of the research period.
