The study by Chun et al. (1) in this issue of the Journal provides important evidence for both the involvement of the phosphatidylinositol 3-kinase (PI3K) signaling pathway in the early stages of lung carcinogenesis and the pharmacologic mechanism of deguelin in decreasing cancer-related increased AKT activity in the PI3K pathway. What makes these findings of great interest is the fact that there have been so few agents, natural or synthetic, tested to date that have shown potential to halt the progression of any form of lung cancer and that the authors have identified potential molecular targets for intervention in premalignant and malignant bronchial epithelial cells.
