BACKGROUND
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.

BACKGROUND
The glomerulus is a complex physiological structure, as well as selective filtration barrier in the control of renal blood flow and blood pressure. Glomerular epithelial cells may play an important role in development of diabetic nephropathy. Apoptosis of the glomerular epithelial cells are characterized by disappearance of a selective filtration barrier. TGF-beta is a key factor in the development of diabetic nephropathy because of its effects on the accumulation of extracellular matrix and mesangial cell proliferation. We examined whether the high glucose and TGF-beta induce the apoptosis in cultured rat glomerular epithelial cells. METHODS: Glomerular epithelial cells were cultured from rat glomeruli and conditioned with different concentration of TGF-beta or high-glucose. We measured apoptosis of cultured rat glomerular epithelial cell conditioning with different concentration of TGF-beta or high-glucose by using DNA electrophoresis. RESULTS: High glucose (25 mM) induced apoptosis of cultured rat glomerular epithelial cells compared to controls. TGF-beta also induced cell death of cultured rat glomerular epithelial cells in dose dependent manner. CONCLUSION: These results suggest that high glucose and TGF-beta-induced cell death of glomerular epithelial cell may play an important role in diabetic nephropathy and proteinuria. Pathway of apoptosis or cell death by high glucose and TGF-beta must be investigated in the glomerular epithelial cells.

BACKGOUND: Inflammation is one of the key mechanisms in the development and progression of atherosclerosis. Accumulating evidence suggests that peroxisome proliferators- activated receptorgamma(PPARgamma) plays an important role in the prevention of arterial inflammation and the formation of atherogenesis. This study was designed to evaluate whether the new synthetic PPARgamma, ascochlorin-6(AS-6) has anti-inflammatory and anti-atherogenic effects in primary cultured rat vascular smooth muscle cells(VSMCs). METHODS: Rat VSMCs were isolated and cultured. Northern and Western blot analyses were performed to evaluate the effects of AS-6 on the expressions of tumor necrosis factor (TNF)-alpha-stimulated fractalkine, monocyte chemoattractant protein(MCP)-1 and vascular cell adhesion molecule (VCAM)-1 in VSMCs. A gel shift assay was performed to examine the mechanism by which AS-6 inhibits the expressions of fractalkine, MCP-1 and VCAM-1. RESULTS: TNF-alpha markedly induced the expressions of fractalkine, MCP-1 and VCAM-1 in primary cultured VSMCs. AS-6 inhibited the expressions of TNF-alpha-stimulated fractalkine, MCP-1 and VCAM-1 in primary cultured VSMCs. The result of the gel shift assay suggested the inhibitory effects of AS-6 on the expressions of TNF-alpha-stimulated fractalkine, MCP-1 and VCAM-1 were mediated through a nuclear factor kappaB associated pathway. CONCLUSION: The present study shows that AS-6 has anti-inflammatory effects on VSMCs, suggesting the possibility for the use of AS-6 for prevention of the development and progression of atherosclerosis.

BACKGROUND
Leptin is mainly secreted from adipose tissue, and it is a crucial factor for metabolic syndrome that is characterized by obesity, insulin resistance, hypertension and dyslipidemia. We measured the serum leptin concentrations and compared them with the body fat distribution and metabolic risk factors in premenopausal normal weight and obese women. METHODS: 231 premenopausal obese women participated in this study. The subjects were grouped based on their body mass index(BMI). The number of normal weight group women(BMI<25kg/m2) and the number of obese group women(BMI> or = 25kg/m2) were 90 and 141, respectively. We measured the plasma leptin concentration and such metabolic risk factors as fasting glucose, insulin, triglyceride(TG), systolic blood pressure(SBP) and diastolic blood pressure(DBP). The subcutaneous adipose tissue area(SAT) and the visceral adipose tissue area(VAT) were determined by computed tomography. The BMI, waist to hip ratio(WHR) and homeostasis model assessment(HOMA-IR) were calculated. RESULTS: In the obese group, the leptin levels were positively correlated with the BMI and SAT as well as with such metabolic risk factors as fasting serum glucose, insulin, HOMA-IR, TG, SBP and DBP. Although leptin levels were positively correlated with BMI and SAT in the normal weight group, they were not correlated with the metabolic risk factors. CONCLUSION: The present study showed that the leptin levels in the normal weight group were not associated with the metabolic risk factors. Therefore, the degree of obesity must be considered before leptin can be used as a predictor for metabolic syndrome including diabetes and coronary heart disease
