Myc-driven medulloblastoma cells treated with Panobinostat (LBH589)

Project description:Mouse MycT58A/DNp53 (MP) medulloblastoma cells were treated with DMSO or HDAC inhibitor (HDACi) panobinostat for 6 or 12 hours in vitro. Gene expression profiling was performed to compare cells treated with panobinostat and DMSO.

Microarray expression data following the treatment of mouse ESC with Panobinostat/LBH589

Project description:Histone acetylation is a dynamic modification regulated by the opposing actions of histone acetyltransferases and histone deacetylases (HDACs). Deacetylation of histone tails results in chromatin tightening and therefore HDACs are generally regarded as transcriptional repressors. Counterintuitively, simultaneous deletion of HDAC1 and HDAC2 in embryonic stem cells (ESC) reduced expression of pluripotent transcription factors, Oct4, Sox2 and Nanog (OSN). By shaping global histone acetylation HDACs indirectly regulate the activity of acetyl-lysine readers, such as BRD4. To examine the direct effects of HDAC (LBH589) and BRD4 (JQ1) inhibition on the ESC transcriptome, we performed precision nuclear run-on and sequencing (PRO-seq) analysis. Both LBH589 and JQ1 caused a marked reduction in the pluripotent network. However, while JQ1 treatment induced widespread transcriptional pausing of genes, HDAC inhibition caused a reduction in both paused and elongating polymerase, suggesting an overall reduction in recruitment of RNAPII. Using enhancer RNA (eRNA) expression to measure enhancer activity, we found that while HDAC activity regulates fewer enhancers than JQ1, LBH589 sensitive eRNAs were preferentially associated with super-enhancers and OSN binding sites. These findings suggest that HDAC activity is required for maintenance of pluripotency by regulating the OSN enhancer network via optimal recruitment of RNA polymerase II.

HER3 targeting augments the efficacy of panobinostat in claudin-low triple-negative breast cancer cells

Project description:Patients with triple-negative breast cancer (TNBC) have a poor prognosis and high relapse rate due to limited therapeutic options. This study was conducted to determine the mechanisms of action of panobinostat, a pan-inhibitor of histone deacetylase (HDAC) and FDA-approved medication for multiple myeloma, in TNBC and to provide a rationale for effective drug combinations against this aggressive disease. RNA sequencing analyses of the claudin-low (CL) TNBC (MDA-MB-231) cells untreated or treated with panobinostat were performed to identify the differentially expressed genes. Adaptive alterations in gene expression were analyzed and validated in additional CL TNBC cells. Tumor xenograft models were used to test the in vivo antitumor activity of panobinostat alone or its combinations with gefitinib, an EGFR-tyrosine kinase inhibitor (TKI). Panobinostat potently inhibited proliferation and induced apoptosis in all TNBC cells tested. However, in CL TNBC cells, this HDAC inhibitor markedly enhanced expression of HER3, which interacted with EGFR to activate both receptors and Akt signaling pathways. Combinations of panobinostat and gefitinib synergistically suppressed CL TNBC cell proliferation and promoted apoptosis in vitro and in vivo. Upregulation of HER3 compromises the efficacy of panobinostat in CL TNBC. Inactivation of HER3 combined with panobinostat represents a practical approach to combat CL TNBC.
