Abstract

Diabetes type 2 is an oxidative stress related disease. This randomized controlled trial was done to evaluate the effect of vitamin D supplementation on thioredoxin binding protein 2 (TBP-2) gene expression in patients with type 2 diabetes. Subjects of this study consist of 28 patients with type 2 diabetes who received 100μg (4000IU) vitamin D and 30 diabetic patients who received placebo for two months. The effect of vitamin D on gene expression of TBP-2 in PBMC cells was measured by RT-PCR at the beginning and at the end of the study. The results of this study showed no significant differences in TBP-2 gene expression between 2 groups, but a significant decrease in serum TBP-2 concentration in vitamin D receiving group at the end of supplementation. It seems that vitamin D supplementation has no effect on the TBP-2 gene expression in PBMC cells.
