AbstractAbstract PDF
The 26S ubiquitin-proteasome system (UPS) is a principal proteolytic pathway of intracellular molecules regulating apoptosis, cell cycle, cell proliferation or differentiation, inflammation and etc. The recent study suggests that the rs1048990 (C/G) polymorphism of the proteasome subunit alpha type 6 (PSMA6) gene is associated with the increase of the risk of myocardial infarction by the dysregulation of IkappaB degradation. We hypothesized that 26S UPS is important in the development of insulin resistance and type 2 diabetes (T2DM) by controlling the degradation of IkappaB and insulin receptor substances as a substrate. We therefore investigated whether the rs1048990 (C/G) polymorphism of PSMA6 gene and the rs2230087 (G/A) polymorphism of proteasome subunit beta type 5 gene (PSMB5), that is chymotrypsin-like protease determining the rate of proteolysis, are associated with susceptibility to T2DM in Korean subjects. METHODS: We examined the polymorphisms of these genes in 309 diabetic subjects and 170 non-diabetic controls. The polymorphisms of rs1048990 (C/G) and rs2230087 (G/A) were genotyped by real-time PCR. RESULTS: The frequency of the G allele of rs1048990 (C/G) and the A allele of rs2230087 (G/A) polymorphisms was significantly higher in diabetic patients (28% and 13%) compared to that in controls (13% and 1%; P = 0.000 and P = 0.000, respectively). Logistic regression analysis of the rs1048990 (C/G) polymorphism showed that the odds ratio (OR) (adjusted for age, smoking, waist circumference, fasting plasma glucose, systolic blood pressure, HDL-C, triglyceride, and total cholesterol) was 3.93 (95% confidence interval [CI], 2.35-6.59; P = 0.000) for the G allele and 5.09 (95% CI, 2.71-9.57; P = 0.000) for CG and GG genotype when compared with the CC genotype. Logistic regression analysis of the rs2230087 (G/A) polymorphism showed that the adjusted OR was 5.70 (95% CI, 1.63-19.98; P = 0.007) for the A allele and 6.08 (95% CI, 1.66-22.29; P = 0.006) for GA and AA genotype when compared with the GG genotype. In multiple logistic regression analysis with T2DM as the independent Variable rs1048990 (C/G) and rs2230087 (G/A) polymorphisms were the predictor for T2DM. CONCLUSION: We suggest that the G allele of rs1048990 (C/G) polymorphism and the A allele of rs2230087 (G/A) polymorphism may be genetic risk factor to type 2 diabetes mellitus in Korean subjects.

AbstractAbstract PDF
The type 2 diabetes is a typical polygenic disease complex, for which several common risk alleles have been identified. Several variants may contribute significantly to the risk of type 2 diabetes conferring insulin resistance of liver, muscle and fat (Pro12Ala) and a relative insulin secretory deficiency (Glu23Lys). In this study, we evaluated the association of Pro12Ala variant of the peroxisome proliferator- activated receptor-gamma and the Glu23Lys variant of the ATP-sensitive potassium channel, Kir6.2 (KCNJ11) with the type 2 diabetes in Korean population. METHOD: This study included 331 subjects consisting of 172 patients with type 2 diabetes and 159 non- diabetic control subjects enrolled from the Kyungpook, Keimyung and Catholic university hospital in Daegu, Korea. We genotyped Kir6.2 (Glu23Lys) and PPARgamma (Pro12Ala) polymorphism and examined their association with the type 2 diabetes. RESULT: In the separate analyses, the Kir6.2 Glu23Lys (P = 0.385) and the PPARgamma Pro12Ala (P = 0.191) polymorphism showed no significant association with type 2 diabetes. In addition, the results of our study showed no evidence of a synergistic interaction between Kir6.2 and PPARgamma gene in each group (P = 0.110, P = 0.276). CONCLUSION: In this study, no association was seen between the genetic polymorphisms of Kir6.2, PPARgamma and type 2 diabetes. However, to clarify whether genetic polymorphisms of these genes contribute to the development of type 2 diabetes, further studies involving larger Korean populations may be needed.
