DNA methylation data for identification of epigenetic targets of resveratrol in triple negative breast cancer cells

Abstract

Previous studies revealed that some bioactive food components have anti-cancer effects. However epigenetic effects of dietary compound resveratrol are largely unknown in breast cancer cells (M.A. Dawson, T. Kouzarides, 2012) [1]. Here we provide novel data and comparisons of DNA methylation status of promoter gene regions in response to resveratrol treatment at 24 h and 48 h versus untreated MDA-MB-231 breast cancer cells. DNA methylation changes were measured using Array-PRIMES method (aPRIMES) followed by whole-genome hybridization using human DNA methylation promoter microarray NimbleGen HG18 Refseq Promoter 3×720 K array. Our data were associated to corresponding changes in mRNA expression in a set of cancer-related genes. Using gene ontology analysis we also identify cancer-related cellular processes and pathways that can be epigenetically reprogramed by resveratrol. Data in this article are associated to the research articles “Methylation Landscape of Human Breast Cancer Cells in Response to Dietary Compound Resveratrol”.
