Friday, March 30th, 2012

Head and neck cancers have repeatedly been linked to infection with human papillomavirus (HPV), with more than half of oropharyngeal squamous cell carcinomas (HNSCCs) positive for HPV. Interestingly, HPV-positive HNSCCs respond better to radiation therapy and have a better prognosis than HPV-negative tumors. But the molecular pathways responsible for their different sensitivities are unclear. In […]

Women infected with human immunodeficiency virus (HIV) constitute one of the populations at highest risk for human papillomavirus-induced cervical cancer. While HIV-infected women in developing countries, such as India, are living longer thanks to antiretroviral therapy, their risk of invasive cervical cancer remains high due to lack of access to affordable and accurate cervical cancer […]

Virus-linked Cancer Gets Help from Host

Friday, December 16th, 2011

Although viruses like HPV (human papilloma virus) are involved in a considerable number of cancers, it takes more than the viral infection for cancer to develop. Host proteins also play important roles. Mary Zutter, M.D., and colleagues are exploring the role of integrins – proteins that help cells attach to each other – in cancer […]
