Inhibiting the phosphoinositide 3-kinase pathway for cancer treatment

Biochem Soc Trans. 2004 Apr;32(Pt 2):393-6. doi: 10.1042/bst0320393.


There is extensive evidence from the molecular and genomic analysis of human cancers that the PI 3-kinase (phosphoinositide 3-kinase)-Akt/PKB (protein kinase B) pathway is deregulated in malignant progression. Furthermore, the causal involvement of PI 3-kinase is supported by gene-knockout mouse models. Prototype inhibitors show evidence of anticancer activity in vitro and in vivo animal models. The recent development of isoform-selective inhibitors shows considerable promise for cancer treatment.
