The novel histone deacetylase inhibitor, LBH589, induces expression of DNA damage response genes and apoptosis in Ph− acute lymphoblastic leukemia cells

Abstract excerpt

We investigated the mechanism of action of LBH589, a novel broad-spectrum HDAC inhibitor belonging to the hydroxamate class, in Philadelphia chromosome-negative (Ph(-)) acute lymphoblastic leukemia (ALL). Two model human Ph(-) ALL cell lines (T-cell MOLT-4 and pre-B-cell Reh) were treated with LBH589 and evaluated for biologic and gene expression responses. Low nanomolar concentrations (IC(50): 5-20 nM) of LBH589...
