Background

Transcription factor 7-like 2 (TCF7L2) is a transcription factor in the Wnt signaling pathway. High levels of TCF7L2 have been reported in most human tissues, including the heart, lung, brain, liver, kidney, placenta, adipose tissues, and pancreatic β-cells. The purpose of this study was to assess the association between TCF7L2 polymorphisms (rs12255372 and rs7903146) and type 2 diabetes mellitus in the city of Jahrom, Iran.

Methods

This case-control study was conducted with 200 patients referred to Diabetes Clinics and 200 healthy subjects in Jahrom City. Biochemical characteristics were first determined. TCF7L2 rs1255372 and rs7903146 polymorphisms were then genotyped using the polymerase chain reaction-restriction fragment length polymorphism method.

Results

T-allele frequencies of both single nucleotide polymorphisms (SNPs) were significantly higher in diabetic patients than in normal glucose-tolerant subjects (rs12255372: 20.3% vs. 14.5%; rs7903146: 28.5% vs. 22.25%). The rs12255372 (G/T) polymorphism analysis showed an odds ratio of 0.473 (95% confidence interval [CI], 0.170 to 1.314; P=0.151) for the TT genotype and 0.646 (95% CI, 0.410 to 1.019; P=0.060) for the TG genotype, compared with the GG genotype. The rs7903146 (C/T) polymorphism odds ratios for TT and TC genotypes were 0.564 (95% CI, 0.280 to 1.135; P=0.109) and 0.751 (95% CI, 0.487 to 1.157; P=0.194) compared with the CC genotype, respectively.

Conclusion

The rs12255372 and rs7903146 SNPs of the TCF7L2 gene were not associated with insulin resistance in the evaluated population.

Background

Estrogen plays a fundamental role in the pathogenesis of type 2 diabetes mellitus (T2DM). Very few studies have shown the association between estrogen receptor α (ERα), PvuII and XbaI gene polymorphisms with T2DM in both men and women. We evaluated the hypothesis that PvuII and XbaI polymorphisms of ERα gene may be associated with T2DM in adult.

Methods

From spring of 2010 to the fall of 2011, a case-control study was performed at clinical centers of Jahrom University of Medical Sciences. We included 174 patients with T2DM including men and women and 174 age, sex, and body mass index frequency-matched health controls. We analyzed the PvuII and XbaI polymorphisms of ERα by using the polymerase chain reaction-based restriction fragment length polymorphism method.

Results

No significant differences between demographic characteristics of control and patients groups were observed. Allele frequencies of both PvuII and XbaI polymorphisms were significantly different between patients and control subjects (P=0.014 vs. P=0.002, respectively). When the group was separated into women and men, logistic regression analysis of genotype distribution of PvuII (pp vs. Pp+PP) in both sexes revealed that there was no significant association of PvuII genotype with men (odds ratio [OR], 1.67; confidence interval [CI], 0.86 to 3.28; P=0.89) and women (OR, 0.96; CI, 0.53 to 1.74; P=0.12).

Conclusion

PvuII and XbaI polymorphisms in ERα are related with T2DM in the inpatient population.
