Fig. 1From: Hypermethylation in the promoter of the MTHFR gene is associated with diabetic complications and biochemical indicatorsMethylation profile of DNA in the promoter of the MTHFR gene in patients with diabetes with and without complications. a Representative samples of the groups studied after MSP (180 bp). MW molecular weight, M methylated, U unmethylated. b Methylation frequency of Control (n = 60), DR (n = 16) and DN (n = 29) (*p < 0.01; **p < 0.03; Χ2). Partial methylation was defined as when the sample was positive for both methylated and unmethylated conditions (MSP)Back to article page
