Abstract
In this issue of Cell, Knight et al. (2006) present a detailed pharmacological analysis of the PI3 kinase (PI3-K) family using small molecule inhibitors. They conclude that p110alpha, a PI3-K isoform, has a critical role in insulin signaling. In a related Cancer Cell paper, Fan et al. (2006) show that blocking activation of both p110alpha and the kinase mTOR with a small molecule inhibitor limits the growth of gliomas.
