- BACKGROUND
Accumulating evidence has suggested that nitric oxide (NO) is involved in the regulation of insulin sensitivity in skeletal muscle. Recent studies also suggested NO as an important molecule regulating mitochondrial biogenesis. This study examined the effect of the NO donor, 3-morpholinosydnonimine (SIN-1), on glucose metabolism in skeletal muscle and tested the hypothesis that NO's effect on glucose metabolism is mediated by its effect on mitochondrial function. METHODS: In Sprague-Dawley (SD) rats treated with SIN-1 for 4 weeks, insulin sensitivity was measured by a glucose clamp study. Triglyceride content and fatty acid oxidation were measured in the skeletal muscle. In addition, mitochondrial DNA content and mRNA expression of mitochondrial biogenesis markers were assessed by real-time polymerase chain reaction and expression of insulin receptor substrate (IRS)-1 and Akt were examined by Western blot analysis in skeletal muscle. In C2C12 cells, insulin sensitivity was measured by 2-deoxyglucose uptake and Western blot analysis was used to examine the expression of IRS-1 and Akt. RESULTS: SIN-1 improved insulin sensitivity in C2C12 cells and skeletal muscles of SD rats. In addition, SIN-1 decreased triglyceride content and increased fatty acid oxidation in skeletal muscle. Mitochondrial DNA contents and biogenesis in the skeletal muscle were increased by SIN-1 treatment. Moreover, SIN-1 increased the expression of phosphor-IRS-1 and phosphor-Akt in the skeletal muscle and muscle cells. CONCLUSION: Our results suggest that NO mediates glucose uptake in skeletal muscle both in vitro and in vivo by improving mitochondrial function and stimulating insulin signaling pathways.

- BACKGROUND
It is well known that the clinical characteristics of diabetes mellitus in Korean people are different from those of Western people. The purpose of this study was to investigate the prevalence of the anti-GAD antibody (GADA) in a large number of Korean patients with adult-onset diabetes. METHODS: The GADA was measured by radioimmunoassay for 11,472 adult-onset diabetic patients who visited the Asan Medical Center from 1998 to 2007. According to the fasting C-peptide levels, we classified the patients into an insulin dependent diabetes mellitus group (IDDM; C-peptide < 0.6 ng/mL) and non-insulin dependent diabetes mellitus group (NIDDM; C-peptide > or = 1.0 ng/mL). Other clinical and laboratory data were obtained from medical records. RESULTS: Among the 11,147 diabetic patients, 9,250 patients were classified as NIDDM, 922 patients were classified as IDDM and 975 patients excluded. Within the latter group 472 patients were to absolute insulin deficient (C-peptide < 0.1 ng/mL). The prevalence of GADA was 22.0% in the IDDM group and 4.7% in the NIDDM group. GADA was more prevalent in younger-onset NIDDM patients (25~40 years of age; 12.4%) than in older-onset NIDDM patients (> or = 40 years of age; 3.8%). The GADA-positive NIDDM patients had lower C-peptide and BMI levels, and higher rates of typical diabetic symptoms and insulin treatment. CONCLUSION: The prevalence of GADA in Korean patients with IDDM and NIDDM was lower than that reported in Western populations. It is thus suggested that autoimmunity is a rarer cause of diabetes in Korean people. However, since over 10% of younger-onset NIDDM patients were positive for GADA, routine GADA measurement in such patients is recommended.
