PI3K pan-inhibition impairs more efficiently proliferation and survival of T-cell acute lymphoblastic leukemia cell lines when compared to isoform-selective PI3K inhibitors
Lonetti, Annalisa; Cappellini, Alessandra; Spartà, Antonino Maria; Chiarini, Francesca; Buontempo, Francesca; Evangelisti, Camilla; Evangelisti, Cecilia; Orsini, Ester; McCubrey, James A.; Martelli, Alberto M. (2015-04)Class I phosphatidylinositol 3-kinases (PI3Ks) are frequently activated in T-cell acute lymphoblastic leukemia (T-ALL), mainly due to the loss of PTEN function. Therefore, targeting PI3Ks is a promising innovative approach ... -

Ruvolo, Vivian R.; Kurinna, Svitlana M.; Karanjeet, Kul B.; Schuster, Todd F.; Martelli, Alberto M.; McCubrey, James A.; Ruvolo, Peter P. (East Carolina University, 2009-12-19)Protein phosphatase 2A (PP2A) is a heterotrimer comprising catalytic, scaffold, and regulatory (B) subunits. There are at least 21 B subunit family members. Thus PP2A is actually a family of enzymes defined by which B ... -
