A combination of temsirolimus, an allosteric mTOR inhibitor, with clofarabine as a new therapeutic option for patients with acute myeloid leukemia
Chiarini, Francesca; Lonetti, Annalisa; Teti, Gabriella; Orsini, Ester; Bressanin, Daniela; Cappellini, Alessandra; Ricci, Francesca; Tazzari, Pier Luigi; Ognibene, Andrea; Falconi, Mirella; Pagliaro, Pasqualepaolo; Iacobucci, Ilaria; Martinelli, Giovanni; Amadori, Sergio; McCubrey, James A.; Martelli, Alberto M. (2012-12)Signaling through the phosphatidylinositol 3-kinase (PI3K) pathway and its downstream effectors, Akt and mechanistic target of rapamycin (mTOR), is aberrantly activated in acute myeloid leukemia (AML) patients, where it ... -
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 ... -
Proapoptotic Activity and Chemosensitizing Effect of the Novel Akt Inhibitor (2S)-1-(1H-Indol-3-yl)-3-[5-(3-methyl-2H-indazol-5-yl)pyridin-3-yl]oxypropan2-amine (A443654) in T-Cell Acute Lymphoblastic Leukemia
Fala, Federica; Blalock, William L.; Tazzari, Pier Luigi; Cappellini, Alessandra; Chiarini, Francesca; Martinelli, Giovanni; Tafuri, Agostino; McCubrey, James A.; Cocco, Lucio; Martelli, Alberto M. (East Carolina University, 2008-09)Constitutively activated AKT kinase is a common feature of T-cell acute lymphoblastic leukemia (T-ALL). Here, we report that the novel AKT inhibitor (2S)-1-(1H-indol-3-yl)-3-[5-(3-methyl-2Hindazol-5-yl)pyridin-3-yl]oxypr ... -
Two hits are better than one: targeting both phosphatidylinositol 3-kinase and mammalian target of rapamycin as a therapeutic strategy for acute leukemia treatment
Martelli, Alberto M.; Chiarini, Francesca; Evangelisti, Camilla; Cappellini, Alessandra; Buontempo, Francesca; Bressanin, Daniela; Fini, Milena; McCubrey, James A. (2012-04)Phosphatidylinositol 3-kinase (PI3K) and mammalian target of rapamycin (mTOR) are two key components of the PI3K/Akt/mTOR signaling pathway. This signal transduction cascade regulates a wide range of physiological cell ...
