title: Drug-resistant phosphatidylinositol 3-kinase: guidance for the preemptive strike.
abstract: In this issue of Cancer Cell, Zunder et al. (2008) describe surprising findings from investigating inhibitor-resistant mutations in the affinity pocket of p110 alpha of phosphatidylinositol 3-kinase (PI3K). Information on these critical residues provides a road map for generating novel PI3K inhibitors that can overcome the anticipated resistance mutations.
