Association between FTO gene polymorphisms and type 2 diabetes mellitus, serum levels of apelin and androgen hormones among Iranian obese women

Abstract Obesity and diabetes prevalence are increasing worldwide. We aimed by this work to detect the possible association of osteoprotegerin (OPG) gene expression with visceral adiposity indices and cardiometabolic risk factors among obese patients. This is research enrolled 150 controls and 150 obese cases subdivided into two subgroups non-diabetic (n = 70) and 80 patients with type 2 diabetes mellitus (T2DM). Circulating OPG expression levels were determined by RT-PCR. Serum OPG concentrations were assessed by ELISA.Our results explored that OPG serum levels were higher in the control group compared to obese women and obese diabetics had higher serum levels of OPG in comparison to obese non-diabetic patients. In obese group, regarding expression levels of OPG were higher than controls in diabetic obese patients, the blood expression levels of OPG were higher than non-diabetics patients. We found positive correlations between parameters of MetS and obesity indices, among them, the highest positive correlation found between VAI. After adjustment of the traditional risk factors, stepwise linear regression analysis test revealed that, OPG expression levels were independently correlated with HbA1c, HDL-cholesterol, and WHR. ROC analysis demonstrated that cutoff values of OPG expression levels and serum levels were 2.226 and 7.5; the AUC were 0.833 (95% CI = 0.821–0.946) and 0.981, respectively. Additionally, the sensitivities and the specificities of OPG expression were (90% and 86.2%), and OPG serum levels (98% and %94), respectively.OPG mRNA and serum levels are useful diagnostic biomarkers discriminate metabolic risk among obesity with or without T2DM.

Number Of Patients

Abstract Type 2 diabetes mellitus (T2DM) is growing in an epidemic manner across the world and India has the world’s largest number of diabetic subjects. The present study was carried out to investigate the association of glutathione-S-transferase (GSTM1, GSTT1) and fat mass and obesity associated (FTO) gene polymorphisms with T2DM patients and controls, and its role in increasing the susceptibility to T2DM. A total of 198 subjects (101 T2DM patients and 97 controls) participated in this study. GSTM1, GSTT1 and FTO gene polymorphisms in the patients and controls were evaluated by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). We observed significant association of GSTM1 positive (p = 0.046) and GSTM1 null (p = 0.046) genotypes with T2DM, while no significant association was found with the FTO gene polymorphism in our study. It seems that the GSTM1 gene polymorphism can be a predictive marker for early identification of a population at risk of T2DM. The potential role of GST and FTO gene polymorphisms as a marker of susceptibility to T2DM needs further studies in a larger number of patients.

The aim of our study was to evaluate the effects of vitamin D supplementation on circulating levels of magnesium and selenium in patients with type 2 diabetes mellitus (T2DM). A total of 126 adult Saudi patients (55 men and 71 women, mean age 53.6 ± 10.7 years) with controlled T2DM were randomly recruited for the study. All subjects were given vitamin D3 tablets (2000 IU/day) for six months. Follow-up mean concentrations of serum 25-hydroxyvitamin D [25-(OH) vitamin D] significantly increased in both men (34.1 ± 12.4 to 57.8 ± 17.0 nmol/L) and women (35.7 ± 13.5 to 60.1 ± 18.5 nmol/L, p < 0.001), while levels of parathyroid hormone (PTH) decreased significantly in both men (1.6 ± 0.17 to 0.96 ± 0.10 pmol/L, p = 0.003) and women (1.6 ± 0.17 to 1.0 ± 0.14 pmol/L, p = 0.02). In addition, there was a significant increase in serum levels of selenium and magnesium in men and women (p-values < 0.001 and 0.04, respectively) after follow-up. In women, a significant correlation was observed between delta change (variables at six months-variable at baseline) of serum magnesium versus high-density lipoprotein (HDL)-cholesterol (r = 0.36, p = 0.006) and fasting glucose (r = - 0.33, p = 0.01). In men, there was a significant correlation between serum selenium and triglycerides (r = 0.32, p = 0.04). Vitamin D supplementation improves serum concentrations of magnesium and selenium in a gender-dependent manner, which in turn could affect several cardiometabolic parameters such as glucose and lipids.
