Project description:ISOS-1, a mouse angiosarcoma cell line, was treated with histone deacetyltransferase inhibitors (HDACI: SAHA and VPA) and a bromodomain and extraterminal domain inhibitor (BETi: JQ1).
Project description:Global mRNA expression profiles of murine primary PDAC cells following JQ1 or SAHA monotherapy as well as JQ1-SAHA combination therapy were collected using Affymetix mouse whole genome array (Mouse Genome 430A 2.0 Array) . Primary PDAC cells isolated from Ptf1aCre/+;Kras+/LSL-G12D;p53lox/lox (Kras;p53) mice were treated either with JQ1 (100 nM) or SAHA (2000 nM) or vehicle 10% (2-Hydroxypropyl)-β-cyclodextrin (Sigma-Aldrich) or as combination therapy with the indicated dosage for monotherapy. Total RNA isolation was performed after 6 hours of treatment. Primary PDAC cells from Ptf1aCre/+;Kras+/LSL-G12D;p53lox/lox (Kras;p53) mice treated either with JQ1, SAHA, vehicle or JQ1-SAHA combination were analyzed by global gene expression analysis.

Project description:Global mRNA expression profiling of patient derived pancreatic carcinoma xenograft Bo63 were collected using Agilent human whole genome array (G4845A AMADID 026652, cRNA 4x44k V2) . Two different sources of RNA were analyzed: 1.) Bo63 xenograft tumors grown on nude mice treated with vehicle only as control. 2.) Bo63 xenograft tumor grown on nude mice treated with JQ1 and SAHA (SAHA 25 mg/kg 1-0-0 and JQ1 50 mg/kg 0-0-1, treatment was imitated when tumor size reached 200 mm³ +/- 20 mm³. Two conditions (vehicle vs JQ1-SAHA treatment), each condition is represented by 3-4 biological replicates
Project description:Suberoylanilide hydroxamic acid (SAHA) and valproic acid (VPA) are both histone deacetylases inhibitor (HDACi), and are able to attenuate the activation of hepatic stelllate cells. To explore the underlying molecular mechanisms, we performed gene expression profile analyses of human hepatic stellate cell line LX2 treated with SAHA or VPA for 24 hours. Duplicate experiments were performed: Untreated LX2, SAHA treated LX2 and VPA treated LX2.

To explore the underlying molecular mechanisms, we performed miRNA expression profile analyses of human hepatic stellate cell line LX2 treated with SAHA or VPA for 24 hours. Duplicate experiments were performed: Untreated LX2, SAHA treated LX2 and VPA treated LX2.

Project description:SAHA/JQ1 reduces in vivo tumorigenesis and proliferation of KP sarcoma cells. This model recapitulates human undifferentiated pleomporphic sarcoma (UPS). We used microarrays to investigate changes in global gene expression in response to these drugs.
Project description:Genome-wide maps of the H3K9 acetylation state in embryonic stem cells (ESCs) before and after treatment with low levels of the histone deacetylase (HDAC) inhibitor valproic acid (VPA). ChIP-seq for 3 samples: untreated E14 cells, cells treated with VPA for 4 hrs and cells treated with VPA for 16 hrs. Unprecipitated DNA was used as the input control (Input).
Project description:Total RNA was extrected from HiDEP-1 (Immortalized erythroid cell line derived from human induced pluripotent stem cells; PMID: 23533656) cultured with HDAC inhibitors, Fluoro-SAHA (FS) or M344 or Valproic acid (VPA), for 24 hours using Rneasy Mini Kit (QIAGEN) by following the manufacture's protocol. After the quality/quantity determination, RNA was subjected to expression analyses using Affymetrix GeneChip® Array / Human Gene 2.0 ST Array
