The Relationship Between Coronary Artery Disease and Genetic Polymorphisms of Melanoma Inhibitory Activity 3

Abstract

BackgroundMelanoma Inhibitory Activity 3 regulates the plasma level of LDL cholesterol. The c.3169 + 315G > A single-nucleotide polymorphism of the MIA3 gene has been reported to be associated with serum coronary artery disease (CAD). However, there have been no studies analyzing the association of this polymorphism with CAD in Iranian individuals with CAD.ObjectivesTherefore, in the present study we have investigated the potential protective effect of the rs3008621 MIA3 polymorphism in 188 subjects with and without CAD.Materials and MethodsGenotyping of the MIA3 gene was undertaken using TaqMan real-time PCR in all subjects. Anthropometric and biochemical features, including HDL, LDL, and TG were assessed in all subjects.ResultsThe CAD patients had significantly (P < 0.05) higher BMI and significantly higher levels of TG, LDL, SBP, and DBP, while the level of HDL was lower compared to that of the control group. the MIA3 gene polymorphism was not associated with CAD in our population sample.ConclusionsThe MIA3 polymorphism is unlikely to play an important role in CAD in the Iranian population. However, further studies are needed in a larger population to confirm this.

Genome-wide association study of fasting proinsulin, fasting insulin, 2-hour postprandial proinsulin, and 2-hour postprandial insulin in Chinese Han people

“…It is reported that the mutation of family members reduces cholesterol and triglyceride levels in mice [31]. Another family member can regulate the plasma low-density lipoprotein-cholesterol concentration and is associated with coronary artery disease [32]. Our study found for the first time that CTAGE11P genetic variants are associated with FPI in the Chinese people.…”
