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 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:To investigate whether microRNAs (miRNAs) were induced by histone deacetylase inhibitors (HDACi) in human gastric cancer cells, the miRNA-seq was used to screen differentially expressed miRNAs in two human gastric cancer cell lines (HGC-27 and AGS) treated with the HDACi vorinostat (SAHA) or vehicle (DMSO).
Project description:Analysis of varied biologic pathways in neuroblastoma SK-N-Be(2)C cells grown in doxorubicin and/or SAHA. We hypothesized that SK-N-Be(2)C cells undergo a mesenchymal change through mesenchymal change resulting in a more invasive as well as drug resistant phenotype, and that the mechanism of SAHAs effect on drug resistance may be revealed through this analysis. Total RNA was isolated from wild type, SAHA treated wild type cells, doxorubicin resistant, and SAHA treated doxorubicin resistant SK-N-Be(2)C cell lines in triplicate.
Project description:Analysis of varied biologic pathways in neuroblastoma SK-N-SH cells grown in doxorubicin and/or SAHA. The hypothesis was that SK-N-SH cells undergo a mesenchymal change through mesenchymal change resulting in a more invasive as well as drug resistant phenotype, and that the mechanism of SAHAs effect on drug resistance may be revealed through this analysis. Total RNA was isolated from wild type, SAHA treated wild type cells, doxorubicin resistant, and SAHA treated doxorubicin resistant SK-N-SH cell lines in triplicate.
Project description:Analysis of gene expression change after 8hr's treatment with 5μM SAHA, which is a histone deacetylase inhibitor, in MDA-MB-231 cell lines.
Project description:We performed a microarray experiment to assess SAHA-induced changes in expression of genes of the homologous recombination DNA repair pathway SKOV-3 ovarian cancer cells were treated with 1µM SAHA or vehicle-control (0.01% DMSO) for 6 or 24 hours, harvested and processed for RNA isolation. Data for both time-points for SAHA and vehicle-control treated cells were obtained in duplicate. Total RNA was isolated using the Qiagen RNeasy Kit (Qiagen, Valencia, CA) according to manufacturer's instructions. cDNA synthesis and hybridization on oligonucleotide microarrays (U133 Plus 2.0 Array GeneChip, Affymetrix, Inc., Santa Clara, CA) were carried out using standard protocols.
