Fig. 2From: Circulating unmethylated CHTOP and INS DNA fragments provide evidence of possible islet cell death in youth with obesity and diabetesValidation of differentially methylated genes using DNA sequencing. DNA was isolated from Newport Green flow-sorted human β cells (from N = 3 independent donors), EndoC-βH1 human fetal β cell-derived line (from N = 3 independent cultures), and 11 human control tissues (each from a single donor). DNA sequencing was performed after bisulfite conversion on the top 5 differentially methylated genes identified by the Infinium HumanMethylation 450 array. a Heatmap of the relative abundance of methylated (red) and hypomethylated (blue) CpG sites indicated for intergenic, SPATS2, and PPP2R3A genomic locations. b Heatmap of the relative abundance of methylated (red) and hypomethylated (blue) CpG sites indicated for the CHTOP geneBack to article page
