Project description:Objective of the study is to determine global changes in gene expression after HDAC inhibitor Trichostatin (TSA) treatment in H69 cell line
Project description:Genome wide expression changes following treatment with the HDACs (Histone Deacetylase Inhibitor) CG-1521 (7.5uM) or TSA (Trichostatin A) were investigated to determine regulatory targets and patterns of the HDAC Inhibitors. Keywords: Expression response to treatment, data was used for a comparison of gene expression and regulation between CG-1521 and TSA in LNCaP Cells
Project description:We report the differential roles of an HDAC inhibitor-TSA during hESC nerual commitment. In the initiation of hESC differentiation, TSA could inhibit the downregulation of pluripotency genes to maintain pluripotency, whereas in the neural commitment stage, TSA could promote neural gene expression to assist hESC nerual determination. Examination of gene expression patterns in hESCs, day 4 or day 8 differentiated cells without or with TSA treatment
Project description:Trichostatin A (TSA) is one of the most potent reversible histone deacetylase (HDAC) inhibitors. In male mice, subcutaneous application of TSA is followed by infertility due to apoptosis of pachytene spermatocytes. To get more insight into the mechanisms underlying this phenomenon, we performed a genome-wide expression analysis of murine testes after TSA treatment. The whole genome transcriptome analysis revealed 507 significantly regulated genes. Validation by real-time quantitative PCR confirmed the expression of 7 from 9 genes tested (78%). Keywords: time course
Project description:In order to identify the TSA responsive genes, we performed a gene expression microarray analysis for the RNAs isolated from TSA-untreated and TSA-treated human keratinocytes

Project description:Based on the cDNA microarrays performed with the RNAs prepared from the differentiated cells at day 3 with or without 24 hrs TSA treatment initiated at day 2, we reveal that the upregulated gene sets were highly enriched for biological functions related to mesoderm development, mesoderm morphogenesis and others. Three independent experiments were performed at each treatment (DMSO or TSA).
