An anonymous reader writes ScieceDaily is reporting that researchers at Ohio State University may have identified a new and unusual tumor suppression gene that could effect cancers of the lung, head, and neck. From the article: “The gene, known as TCF21, is silenced in tumor cells through a chemical change known as DNA methylation, a process that is potentially reversible. The findings might therefore lead to new strategies for the treatment and early detection of lung cancer, a disease that killed an estimated 163,510 Americans in 2005. The study could also lead to a better understanding of the molecular changes that occur in tumor cells during lung-cancer progression.”
