Abstract: | In this study, we induced chemical damage of C2C12 myoblasts that had differentiated into myotubes with glycerol, and four sulfation enzymes for chondroitin sulfate (CS) [carbohydrate sulfotransferase (Chst) 12, Chst15 and Chst3 and uronyl 2-O-sulfotransferase (UST)] and two CS degradation enzymes [hyaluronidase (Hyal) 1 and Hyal2] were examined for changes in gene expression. Treatment of myoblasts with 5% glycerol significantly increased the expression levels of the sulfation enzymes Chst12 and Chst15 and the degradation enzymes Hyal1 and Hyal2. However, the expression levels of the other two genes (Chst3 and Ust) showed no change. Differences in the expression levels of these enzymes may help to understand the difference in responsiveness of myoblasts to glycerol after muscle injury in vivo or in vitro. |
