Abstract:   (638 Views)
Background: Type II diabetes is a chronic inflammatory condition that is associated with a combination of genetic and environmental factors. Tumor necrosis factor alpha or TNF-α as an adipocyte cytokine, which affects the signaling pathway of insulin, can contribute to insulin resistance in type 2 diabetes patients. Considering the importance of epigenetic changes in multifactorial diseases, this study aimed to investigate TNF-α promoter methylation in patients with type 2 diabetes.
Methods: This study was performed on 61 patients with type 2 diabetes and 31 non-diabetic patients. The Groups were matched in terms of demographic characteristics. The lipid profiles were measured by standard kits. TNF-α promoter methylation levels were measured by bisulphite treatment method, Nested PCR and sequencing.
Results: There was no association between TNF-α promoter methylation gene promoter and type 2 diabetes in the studied groups. Also, there was no association between TNF-α promoter methylation in diabetic and non-diabetic groups between males and females.
Conclusion: The epigenetic changes in cytokines that contribute to insulin resistance in type 2 diabetic patients seem to be ineffective in peripheral blood samples, and other tissues may need to be investigated in this regard.
