JCI early table of contents for Nov. 12, 2012

adenocarcinoma is a highly invasive form of lung cancer that is associated with a decrease in a gene regulatory protein known as NKX2-1. In a study published in the Journal of Clinical Investigation, researchers led by Jeffrey Whitsett at Cincinnati Children's Hospital demonstrated that loss of one copy of the Nkx2-1 gene and the expression of an activated form of the oncogene Kras caused mucinous adenocarcinoma in mice. Interestingly, loss of one copy of Nkx2-1 in combination with the expression of another common lung-cancer associated gene, Egfr, did not cause carcinogenesis. These results suggest that the function of Nkx2-1 is context dependent and indicate that the genotype of mucinous adenocarcinomas should influence the choice of treatment.
