Subjugation of TGFβ Signaling by Human Papilloma Virus in Head and Neck Squamous Cell Carcinoma Shifts DNA Repair from Homologous Recombination to Alternative End Joining

Abstract excerpt

PURPOSE: Following cytotoxic therapy, 70% of patients with human papillomavirus (HPV)-positive oropharyngeal head and neck squamous cell carcinoma (HNSCC) are alive at 5 years compared with 30% of those with similar HPV-negative cancer. Loss of TGFβ signaling is a poorly studied consequence of HPV that could contribute to patient outcome by compromising DNA repair. EXPERIMENTAL DESIGN: = 10) were used to define...
