Abstract:Introduction
Activating mutations of the KIT class III receptor tyrosine kinase (TK) are associated with the pathophysiology of acute leukemia, especially core binding factor leukemia (CBFL), and systemic mastocytosis (SM). Despite considerable antiproliferative and proapoptotic activity of several KIT TK inhibitors in vitro, clinical efficacy in AML and SM is generally moderate. We hypothesized that resistance to therapy is promoted by activation of alternative signaling pathways. Previously… 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.
