Abstract

Acute leukemias are aggressive neoplasias characterized by clonal proliferation with replacement and accumulation of neoplastic blasts in bone marrow or peripheral blood. Despite great advances in understanding the complexity behind the molecular changes in acute leukemia in recent years, very little has been translated into new therapies. Stathmin 1 is a microtubule destabilizing protein that integrates multiple signaling pathways, is highly expressed in leukemia cells (cell lines and primary cells) and plays a role relevant to the maintenance of the leukemia phenotype, including increased cell proliferation and clonogenicity. However, the translation of this knowledge obtained through genetic inhibition of Stathmin 1 (siRNA or shRNA) in pharmacological therapy, as well as the identification of selective inhibitors for Stathmin 1, still remain little explored. Thus, the objectives of this research project, using well established acute leukemia models, are: (i) to identify potential Stathmin 1 inhibitors by chemoinfomatics (ii) to test the effects of the selected compounds in relation to the Stathmin 1 activity and microtubule stability; (ii) evaluate the biological activity of the selected compounds in relation to cell viability, proliferation, clonogenicity, apoptosis, cell cycle progression; and related cell signaling pathways.
