| Outline of Final Research Achievements |
It is well known that fat storage in skeletal muscle is higher in obese people than that in healthy people. Insulin resistance is associated with high levels of stored lipids in skeletal muscle cells. However, it is not clear why enhanced insulin sensitivity is observed in endurance athletes who had high lipid storage in skeletal muscle.
Our results shows that mitochondria and lipid droplet are existed around nucleus, and nucleus and mitochondria go around lipid droplet in C2C12 cell culture. We therefore hypothesized that localization of mitochondria and lipid droplet in skeletal muscle cells may be associated with insulin resistance.
