Hyperactivation of the PI 3-kinase/AKT pathway is a driving force of many cancers. Here we identify the AKT-inactivating phosphatase PHLPP1 as a prostate tumor suppressor. We show that Phlpp1-loss causes neoplasia and, on partial Pten-loss, carcinoma in mouse prostate. This genetic setting initially triggers a growth suppressive response via p53 and the(More)
Combining representational oligonucleotide microarray analysis (ROMA) of tumor DNA with fluorescence in situ hybridization (FISH) of individual tumor cells provides the opportunity to detect and validate a wide range of amplifications, deletions, and rearrangements directly in frozen tumor samples. We have used these combined techniques to examine 101(More)
Understanding the specificity of protein-protein interaction mediated by domains and their ligands will have strong impact on basic and applied research. Visual inspection of WW domain sequences prompted a general classification of the domains into two large subfamilies. One subfamily contains two consecutive aromatic residues in the beta 2 strand of the(More)
