Induction Of Apoptosis By The Dual PI3K/Mtor Inhibitor NVP-BEZ235 Is Impaired By a Profound G1/G0 Arrest In Acute Leukemia Which Can Be Overcome By Combination Approaches
Abstract:Introduction
Constitutive phosphorylation of AKT is frequently found in acute leukemia. In a proportion of patients, activation of the PI3K/AKT pathway can be linked to gain-of-function tyrosine kinase mutations. We have previously shown that TKI only incompletely inactivate AKT signaling. PI3K/AKT pathway inhibitors are attractive for targeting this pathway. However, most inhibitors lead to G1/G0 arrest. Likely for this reason, response rates to PI3K inhibitor treatment were moderate in vari… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
