Genome-wide Analysis of Histone Methylations in Memory CD8+ T Cells

ABSTRACT: Histone methylations play a major role in regulating the chromatin state and gene expression, yet little is known about their involvement in differential gene expression and function of memory CD8 T cells. Here, we report a genome-wide analysis of two histone H3 methylations (H3K4me3 and H3K27me3) and gene expression in naïve, central (TCM) and effector (TEM) memory CD8 T cells. Analysis of 16,314 annotated genes in CD8 T cell subsets revealed that gene expression were positively correlated with the levels of H3K4me3 and negatively correlated with the levels of H3K27me3 in these gene loci. The correlation between differential H3K4me3 orH3K27me3 levels with gene expressions in memory CD8 T cells displayed four distinct modes: repressive, active, poised, and bivalent, reflecting their com
