Genomic DNA methylation levels analyzed by high-performance liquid chromatography. (A) Sample chromatogram map. The peak time of sample dC was 7.942 min and that of 5mdC was 10.025 min. Nucleotides: A, adenine; T, thymine; G, guanine; dC, deoxidized cytosine; 5mdC, deoxidized 5-methyl cytosine. (B) Quantified genomic DNA methylation levels in the different groups. The genomic DNA methylation rate was 5.23±0.09% in the DN group, 4.71±0.03% in the NDN group and 4.37±0.01% in the NDM group. There were no significant differences among the groups. NDM, non-diabetes control; NDN, diabetes without nephropathy; DN, diabetes with nephropathy; VWD, variable wavelength detector.
