Worldwide, 1,000,000 people succumb to lung cancer annually. Many of these
deaths could be prevented if there were better screening methods to uncover
the disease when it is limited and most responsive to intervention. Novel
biomarkers of early-stage disease are therefore needed. By applying the pri
nciple of "oncology recapitulates ontogeny", we have discovered three homeo
box (HOX) genes that are inappropriately expressed in the majority of lung
tumors. Understanding the role of these inappropriately expressed genes in
lung epithelial cell carcinogenesis may not only augment early detection, b
ut may also offer new avenues of treatment of this disease. (C) 2001 by Rad
