Abstract

Background: The role of angiotensin II type 1 receptor (AT1R) as a key player in type 2 diabetes mellitus (T2DM) complicated with hypertension remains controversial. The present case-control study systematically investigated the association between gene the correct variation type in the angiotensin II type 1 receptor (AT1R) gene and type 2 diabetes mellitus complicated with hypertension in the Han population from the Inner Mongolia region, China.

Method: Here, state which variants were analysis, including age, occupation, triglyceride, systolic, diastolic, sex, culture, marital status, smoking, alcohol, BMI (body mass index), SBP (systolic blood pressure), DBP (diastolic blood pressure), TG (triglyceride), TC (total cholesterol), HDL-C (high-density lipoprotein cholesterol), LDL-C (low-density lipoprotein cholesterol), FPG (fasting plasma glucose). Genomic DNA was extracted from samples from 202 type 2 diabetic patients with hypertension and 216 type 2 diabetic patients without hypertension.

Results: Non-conditional regression analysis showed that in comparison with the TT genotype, the presence of the CC genotype for the T573 site of the AT1R gene increased the risk for diabetes mellitus complicated with hypertension by 3.219-fold (OR = 3.219, 95% CI: 1.042-9.941, P = 0.042). The results from multivariate linear regression analysis suggested the rs5182 polymorphism in the AT1R gene to be associated with diastolic blood pressure (P = 0.032). No other associations were found between the incidence of disease and the correct variation type at other sites of the AT1R gene.

Conclusions: Our results suggest that the rs5182 polymorphism in the AT1R gene is associated with diabetes complicated by hypertension in the Han population of Inner Mongolia.
