We screened CG sites of methylation in blood leukocytes from different age populations, picked up genes with age-related increase of CG methylation content more than 15%, and validated immune related genes with CG hypermethylation involved in lymphocyte differentiation in the aged population. We found that 12 genes (EXHX1、 IL-10、 TSP50、 [[GSTM1]]、SLC5A5、SPI1、F2R、[[LMO2]]、PTPN6、FGFR2、MMP9、MET) were associated with promoter or exon one DNA hypermethylation in the aged group. Two immune related genes, [[GSTM1]] and [[LMO2]], were chosen to validate its aging-related CG hypermethylation in different leukocytes. We are the first to validate that [[GSTM1]]_P266 and [[LMO2]]_E128 CG methylation contents in T lymphocytes but not polymorphonuclear cells (PMNs) or mononuclear cells (MNCs) were significantly increased in the aged population. The [[GSTM1]] mRNA expression in T lymphocytes but not PMNs or MNCs was inversely associated with the [[GSTM1]] CG hypermethylation levels in the aged population studied. Further studies showed that lower [[GSTM1]] CG methylation content led to the higher [[GSTM1]] mRNA expression in T cells and knockdown of [[GSTM1]] mRNA expression decreased type 1 T helper cell (Th1) differentiation in Jurkat T cells and normal adult [[CD4]] T cells. The [[GSTM1]]_P266 hypermethylation in the aged population associated with lower [[GSTM1]] mRNA expression was involved in Th1 differentiation, highlighting that modulation of aging-associated [[GSTM1]] methylation may be able to enhance T helper cell immunity in the elders.<br /> |mesh-terms=* Adaptor Proteins, Signal Transducing<br /> * Aging<br /> * Cell Differentiation<br /> * CpG Islands<br /> * DNA Methylation<br /> * Epigenesis, Genetic<br /> * Gene Expression Profiling<br /> * Gene Expression Regulation<br /> * Glutathione Transferase<br /> * Humans<br /> * LIM Domain Proteins<br /> * Leukocytes<br /> * Proto-Oncogene Proteins<br /> * RNA, Messenger<br /> * T-Lymphocytes<br /> |keywords=* DNA hypermethylation<br /> * GSTM1<br /> * Gerotarget<br /> * T cell differentiation<br /> * aging<br /> * epigenetic<br /> |full-text-url=https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5564710<br /> }}</div>
