Title: Transcription profiling by array of trichostatin-A treated gastric cancer cell lines      
dateReleased:
10-21-2016
description:
Histone deacetylation is involved in epigenetically mediated tumor suppressor genes silencing. The screen of genes modulated by histone acetylation in gastric cancer maycontribute to the identification of potential therapeutic targets. In this experiment we aimed to identify differentially expressed genes by comparing Trichostatin A (TSA)-treated and non-treated gastric cancer cell lines. TrichostatinA (TSA) belongs to the hydroxamic acid chemical class histone deacetylaseinhibitors, which selectively inhibit the class I and II mammalian histonedeacetylase families. As expected, TSA acetylates promoter regions, or disables corepressors, resulting in increased gene expression. The ACP02 and ACP03 gastric cancer cell lines used in this experiment were previously established by our research group from primary gastric adenocarcinomas classified as diffuse and intestinal types, respectively. Both cell lines present chromosome 8 trisomy, MYC amplification, and TP53 loss of copy. Moreover, ACP03 is able to start a tumorigenesis process in Cebus apellas.
