Prevention of Oxidative Stress-Induced Apoptosis of C2C12 Myoblasts by a Cichorium intybus Root Extract

抄録

Cell injury associated with reactive oxygen species (ROS) has been reported in various muscular disorders. We found that a Cichorium intybus (Cii) extract reduced H₂O₂-induced viability loss in C2C12 myoblasts, inhibited oxidative stress-induced apoptosis and increased intracellular heat shock protein 70 (Hsp 70) expression. Cii also inhibited the level of intracellular ceramide. These results indicate that Cii may prevent skeletal muscle atrophy by inducing the expression of Hsp 70 and inhibiting the level of ceramide.
