Viruses have developed sophisticated strategies to evade host defenses and facilitate the production and spread of progeny. HPV 16, whose immune evasion activities can contribute to cervical cancer, is a prime example of such a virus. In this study, we examined the influence of HPV 16 E6 on TRAIL-induced FADD-dependent and -independent pathways in two cellular models: HCT116 colon carcinoma cells and U2OS osteosarcoma cells. We show that transfection of the HPV 16 E6 oncogene into HCT116 cells provides protection from TRAIL-mediated apoptosis. Additionally, we demonstrate that the protection provided by E6 is dose-dependent because higher levels of E6 provide …
