Chondroitin sulfate E downregulates N-cadherin and suppresses myotube formation.

Myogenesis, the formation of muscle fibers, is affected by certain glycoproteins, including chondroitin sulfate (CS), which are involved in various cellular processes. We aimed to investigate the mechanism underlying CS-E-induced suppression of myotube formation using the myoblast cell line C2C12. Differentiated cells treated with 0.

Ontogeny of gene expression of group IB phospholipase A₂ isoforms in the red sea bream, Pagrus (Chrysophrys) major.

The red sea bream (Pagrus major) was previously found to express mRNAs for two group IB phospholipase A(2) (PLA(2)) isoforms, DE-1 and DE-2, in the digestive organs, including the hepatopancreas, pyloric caeca, and intestine. To characterize the ontogeny of the digestive function of these PLA(2)s, the present study investigated the localization and expression of DE-1 and DE-2 PLA(2) genes in red sea bream larvae/juveniles and immature adults, by in situ hybridization. In the adults, DE-1 PLA(2) mRNA was expressed in pancreatic acinar cells.
