The role of phosphoinositide 3-kinase pathway inhibitors in the treatment of lung cancer.

The phosphoinositide 3-kinase signaling network is widely implicated in the pathogenesis of human cancer. This pathway is commandeered by cancer cells to promote unrestrained cellular growth and survival. In this brief review, we speculate about the uses of inhibitors of phosphoinositide 3-kinase signaling as treatments for human cancers, with an emphasis on non-small cell lung cancer.
