Research Abstract |
The aim of this study is to clarify the significance of hydroxymethyl CpG (hmCpG) in breast cancer cells. The hmCpG is thought to be the first step in demethylation mechanism of methylated CpG, and to play an important roles in epigenetic gene regulation in cancer. In this study, to screen differentially hydroxymethylated regions (DHMR), we conducted to methylation microarray analysis to identify differentially hypomethylated regions, using ATCC's breast cancer cell line panels. According to the detailed analysis, we identified subtype specific hypomethylated regions in Luminal type and triple negative breast cancers, which would be candidate regions of DHMR. On the other hand, we established a gene induction system of TET1/2/3 gene families, using Lenti-virus vector system. It will help the further functional analysis of TET1/2/3 genes in breast cancer cells.
