1Epigenetic profiles of pre-diabetes transitioning to type 2 diabetes and nephropathy显示文摘AIM: To examine DNA methylation profiles in a longitudinal comparison of pre-diabetes mellitus(Pre-DM) subjects who transitioned to type 2 diabetes mellitus(T2DM).METHODS: We performed DNA methylation study in bisulphite converted DNA from Pre-DM(n = 11) at baseline and at their transition to T2 DM using Illumina Infinium Human Methylation27 Bead Chip, that enables the query of 27578 individual cytosines at Cp G loci throughout the genome, which are focused on the promoter regions of 14495 genes.RESULTS: There were 694 Cp G sites hypomethylated and 174 Cp G sites hypermethylated in progression from Pre-DM to T2 DM, representing putative genes involved in glucose and fructose metabolism, inflammation, oxidative and mitochondrial stress, and fatty acid metabolism. These results suggest that this high throughput platform is able to identify hundreds of prospective Cp G sites associated with diverse genes that may reflect differences in Pre-DM compared with T2 DM. In addition, there were Cp G hypomethylation changes associated with a number of genes that may be associated with development of complications of diabetes, such as nephropathy. These hypomethylation changes were observed in all of the subjects.CONCLUSION: These data suggest that some epigenomic changes that may be involved in the progression of diabetes and/or the development of complications may be apparent at the Pre-DM state or during the transition to diabetes. Hypomethylation of a number of genes related to kidney function may be an early marker for developing diabetic nephropathy.Thomas A Vander Jagt Monica H Neugebauer Marilee Morgan Donald W Bowden Vallabh O Shah 2015World Journal of Diabetes2015,6,9:5
