Vanderbilt-Ingram Cancer Center researchers have identified how one of the genes most commonly mutated in lung cancer may promote such tumors. The investigators found that the protein encoded by this gene, called EPHA3, normally inhibits tumor formation, and that loss or mutation of the gene -- as often happens in lung cancer -- diminishes this tumor-suppressive effect, potentially sparking the formation of lung cancer. The findings, published July 24 in the Journal of the National Cancer Institute, could offer direction for personalizing cancer treatments and development of new therapies.
