Abstract 2958: Discovering therapeutic epigenetic targets using whole genome siRNA screening
Conclusions: A whole genome siRNA screen in combination with the DNMT inhibitor decitabine identified many new target genes that might be epigenetic regulators and potential targets for drug development.Citation Format: Yasuyuki Okamoto, Woonbok Chung, Judith Garriga, Jaroslav Jelinek, Jean-Pierre J.

Abstract 373: An siRNA screen identifies CHD4 as a target for epigenetic therapy
In this study, we used an unbiased screen to investigate therapeutic targets which might be effective combination with DNMT inhibitors in reactivating hypermethylated genes. Methods: We screened an siRNA library targeting 188 gene predicted as epigenetic regulators using colon cancer cells that harbor a GFP locus stably integrated and silenced by a hypermethylated cytomegalovirus (CMV) promoter. GFP-positive cell percentages were measured using Guava EasyCyte Plus flow analyzer software. For genome wide gene expression analysis, affymetrix microarrays were performed. DNA methylation status was evaluated by pyrosequencing a...
