| Outline of Final Research Achievements |
Our epidemiological studies have revealed that mitochondrial DNA (m.) 1382 A>C polymorphism is associated with T2DM with lower physical activity in men, but not in women. However, the mechanism has not been proved yet. The purposes of this study is to clarify the effect of MOTS-c (K14Q) on glucose clearance in mice. CD1 mice were used in high fat diet-induced obesity and intraperitoneal glucose tolerance test (IPGTT). Mice were treated with MOTS-c (MOTS-c group, 0.5mg/kg/day; IP), MOTS-c (K14Q group), or distilled water (vehicle group), once in 2 days for 21 days. In male mice, body weight growth curve is lower in MOTS-c group than K14Q and vehicle group. MOTS-c group is also better in IPGTT than K14Q group. There are no differences in body weight growth curve among three type groups in female mice. These results suggest that MOTS-c amino acid replacement (K14Q) by m.1382 A>C polymorphism may influence prevalence of T2DM in lower activity men.
