Although data regarding the role of the Notch pathway in human lung cancer are still limited, fetal lung developmental studies suggest that Notch signaling plays a critical role in regulating airway epithelial development. The moderate hypotrophic phenotype of lungs from animals bearing a Hes1 mutation, and the expression of Notch components in the distal lung bud during branching morphogenesis, together suggest that Notch may play a role in normal lung growth, especially in Clara cell precursors. Non-small cell lung cancers, including adenocarcinoma, appear to actively utilize this conserved developmental pathway. Pharmacologic inhibition of the Notch pathway is a potential experimental approach to lung cancer treatment.
