(Submitter supplied) The BET (bromodomain and extra terminal) protein family members including BRD4 bind to acetylated lysines on histones and regulate the expression of important oncogenes, e.g., MYC and BCL2. Here we demonstrate the sensitizing effects of the histone hyperacetylation inducing pan-histone deacetylase inhibitor (HDI) panobinostat (PS) on human AML blast progenitor cells (BPCs) to the BET protein inhibitor JQ1. more...

(Submitter supplied) The PROTAC (proteolysis-targeting chimera) ARV-825 recruits bromodomain and extraterminal (BET) proteins to the E3 ubiquitin ligase cereblon, leading to degradation of BET proteins, including BRD4. Whereas the BET-protein inhibitor (BETi) OTX015 caused accumulation of BRD4, treatment with equimolar concentrations of ARV-825 caused sustained and profound depletion (>90%) of BRD4 and induced significantly more apoptosis in cultured and patient-derived (PD) CD34+ post-MPN sAML cells, while relatively sparing the CD34+ normal hematopoietic progenitor cells. more...

(Submitter supplied) To determine the global transcriptomic changes induced by treatment with the Beta Catenin antagonist BC2059 in AML cells The canonical WNT-β-catenin pathway is essential for self-renewal, growth and survival of AML stem/blast progenitor cells (BPCs). Deregulated WNT signaling inhibits degradation of β-catenin, causing increased nuclear translocation and co-factor activity of β-catenin with the transcriptional regulator TCF4/LEF1 in AML BPCs. more...

(Submitter supplied) To determine the global transcriptome changes in mantle cell lymphoma cells following treatment with the BET bromodomain antagonist, JQ1 Mantle Cell Lymphoma (MCL) cells exhibit increased B cell receptor and NFkB activities. The BET protein BRD4 is essential for the transcriptional activity of NFkB. Here, we demonstrate that treatment with the BET protein bromodomain antagonist (BA) JQ1 attenuates MYC and CDK4/6, inhibits the nuclear RelA levels and the expression of NFκB target genes including Bruton’s Tyrosine Kinase (BTK) in MCL cells. more...

Acute myeloid leukemia (AML) is a heterogeneous group of hematopoietic stem cell disorders characterized by defects in myeloid differentiation and increased proliferation of neoplastic hematopoietic precursor cells. Outcomes for patients with AML remain poor, highlighting the need for novel treatment options. more...

(Submitter supplied) MYC-amplified medulloblastomas are highly lethal tumors. BET bromodomain inhibition was recently described to downregulate MYC-associated transcriptional activity in various cancer subtypes. To investigate whether JQ1, a BET bromodomain inhibitor is downregulation MYC and MYC-associated transcriptional activity, we performed global gene expression profiling of five medulloblastomas MYC-amplified patient-derived cell lines treated by JQ1 and the inactive form of JQ1.

(Submitter supplied) Two human acute lymphoblastic leukemia cell lines were treated with a BET bromodomain inhibitor that blocks BET association with chromatin. These cell lines, MHH-CALL4 and MUTZ-5, each carry translocation of the CRLF2 gene into the IgH locus, and their growth was found to be susceptible to BET inhibition. Gene expression changes were analyzed in each cell line versus vehicle control.

(Submitter supplied) Diffuse intrinsic pontine glioma (DIPG) is a fatal pediatric brain tumor with limited therapeutic options. The majority of cases of DIPG exhibit a mutation in histone 3 (H3K27M) that results in oncogenic transcriptional aberrancies. We show here that DIPG is vulnerable to transcriptional disruption using either bromodomain inhibition or CDK7 blockade. We observe that targeting oncogenic transcription through either of these methods synergizes with HDAC inhibition and that DIPG cells resistant to HDAC inhibitor therapy retain sensitivity to CDK7 blockade. more...

(Submitter supplied) Epigenetic pathways regulate gene expression by controlling and interpreting chromatin modifications. Cancer cells are characterized by altered epigenetic landscapes and commonly exploit the chromatin regulatory machinery to enforce oncogenic gene expression programs. While chromatin alterations are, in principle, reversible and often amendable to drug intervention, the promise of targeting such pathways therapeutically has been hampered by our limited understanding of cancer-specific epigenetic dependencies. more...

(Submitter supplied) Pediatric AML cell lines (MV4;11, AML-193 and THP-1) were treated with DNA hypomethylating agent (azacytidine) and a pan histone deactylase inhibitor (panobinostat) alone or in combination. Treatment of AML cell lines with these epigenetic drugs synergistically suppresses cell viability in vitro and in xenograft models in vivo. Data show differential regulation of gene expression in AML cell lines by epigenetic drugs at concentrations which retained cell viability at a minimum of 75% even in the combination treatment.

(Submitter supplied) BCL6 is a transcription repressor that plays a crucial role in germinal center formation and lymphomagenesis. However, its role in myeloid malignancies remains unclear. Here, we explored the role of BCL6 in acute myeloid leukemia (AML). Heterogeneous levels of BCL6 were found across AML cell lines and primary AML samples. Cells with higher levels of BCL6 were indeed sensitive to treatment with BCL6 inhibitors. more...
