Abstract Despite high initial response rates, acute myeloid leukemia (AML) treated with the BCL-2–selective inhibitor venetoclax (VEN) alone or in combinations commonly acquires resistance. We performed gene/protein expression, metabolomic and methylation analyses of isogenic AML cell lines sensitive resistant to VEN, identified activation RAS/MAPK pathway, leading increased stability higher levels MCL-1 protein, as a major acquired mechanism VEN sustained survival maintained mitochondrial...

Targeted therapies designed to exploit specific molecular pathways in aggressive cancers are an exciting area of current research. Mixed Lineage Leukemia (MLL) mutations such as the t(4;11) translocation cause leukemias that refractory conventional treatment. The produces MLL/AF4 fusion protein activates key target genes through both epigenetic and transcriptional elongation mechanisms. In this study, we show patient cells express high levels BCL-2 highly sensitive treatment with...

Abstract T-cell acute lymphoblastic leukemia (T-ALL) is commonly driven by activating mutations in NOTCH1 that facilitate glutamine oxidation. Here we identify oxidative phosphorylation (OxPhos) as a critical pathway for cell survival and demonstrate direct relationship between , elevated OxPhos gene expression, acquired chemoresistance pre-leukemic leukemic models. Disrupting with IACS-010759, an inhibitor of mitochondrial complex I, causes potent growth inhibition through induction...

BCL-XL and BCL-2 are key anti-apoptotic proteins validated cancer targets. 753B is a novel BCL-XL/BCL-2 proteolysis targeting chimera (PROTAC) that targets both to the von Hippel-Lindau (VHL) E3 ligase, leading BCLX L/BCL-2 ubiquitination degradation selectively in cells expressing VHL. Because platelets lack VHL expression, spares on-target platelet toxicity caused by first-generation dual inhibitor navitoclax (ABT-263). Here, we report pre-clinical single-agent activity of against...

Abstract Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematologic malignancy with poor outcomes conventional therapy. Nearly 100% of BPDCNs overexpress interleukin 3 receptor subunit alpha (CD123). Given that CD123 differentially expressed on the surface BPDCN cells, it has emerged as an attractive therapeutic target.

In Vietnam veterans, exposure to military toxicants, such as Agent Orange, may be associated with lymphoid malignancies. Toxicant increase the likelihood of being diagnosed concurrent malignancies, which can occur composite, discordant, or transformed lymphomas. We conducted a large, retrospective case-control study using national VA Central Cancer Registry identify cases malignancies compared controls single and association Orange. The occurrence was rare (n = 128/32,889, 0.4%). most common...

The peripheral T-cell lymphomas (PTCL) are rare and heterogeneous diseases characterized by an unfavorable prognosis. Chemotherapy is standard upfront treatment in most patients, but responses short-lived with few FDA-approved "novel" agents available. We sought to define the impact of these novel as single or clinical trials on outcomes patients PTCL. From January 1994 May 2019, adult PTCL who were managed at our institution included this analysis. In addition incomplete data, those...
