HPV is responsible for nearly all cases of cervical cancer and 95 percent of anal cancers. It is the most common sexually transmitted disease, infecting more than 79 million Americans. Most have no idea that are infected or that they could be spreading it.

"Human papillomavirus causes a lot of cancers. Literally thousands upon thousands of people get cervical cancer and die from it all over the world. Cancers of the mouth and anal cancers are also caused by human papillomaviruses," said UVA researcher Anindya Dutta, PhD, of the UVA Cancer Center. "Now there's a vaccine for HPV, so we're hopeful the incidences will decrease. But that vaccine is not available all around the world, and because of religious sensitivity, not everybody is taking it. The vaccine is expensive, so I think the human papillomavirus cancers are here to stay. They're not going to disappear. So we need new therapies."

HPV - Foe - Scientists - Researchers - Grasp

HPV has been a stubborn foe for scientists, even though researchers have a solid grasp of how it causes cancer: by producing proteins that shut down healthy cells' natural ability to prevent tumors. Blocking one of those proteins, called oncoprotein E6, seemed like an obvious solution, but decades of attempts to do so have proved unsuccessful.

Dutta and his colleagues, however, have found a new way forward. They have determined that the virus takes the help of a protein present in our cells, an enzyme called USP46, which becomes...
