| Outline of Final Research Achievements |
In HFD-induced NASH model mice, intraperitoneal injection of OSM improved NASH as well as glucose intolerance, insulin resistance, and adipose tissue inflammation. OSM decreased food intake and intestinal lipid absorption, but did not affect on the body temperature and locomotor activity. In addition, the direct beneficial effects of OSM on lipid storage in hepatocytes were observed when OSM was injected into this model mice intraportally.
Swimming and moderate-intensity running induced the expression of OSM in the calf muscle, but not in the quadriceps. High-intensity running induced the expression of OSM in both the calf muscle and the quadriceps. The expression of OSMRβ was observed in the endothelial cells, satellite cells, and mesenchymal progenitor cells in the skeletal muscle, suggesting that exercise may exert the therapeutic effects on NASH through the action of exercise-induced OSM on these cells.
