Recombinant ADAMTS1 promotes muscle cell differentiation and alleviates muscle atrophy by repressing NOTCH1.

ABSTRACT: A disintegrin and metalloproteinase with thrombospondin motifs 1 (ADAMTS1) plays crucial roles in various biological processes, including myogenesis, by modulating the neurogenic locus notch homolog protein 1 (NOTCH1) signaling pathway. However, the mechanisms through which ADAMTS1 regulates myogenesis remain unclear. In this study, we generated recombinant ADAMTS1 mutants and determined their effects on muscle cell differentiation, focusing on the regulation of NOTCH1 signaling. Treatment of C2C12 cells with recombinant ADAMTS1 protein enhanced muscle cell differentiation. Meanwhile, ADAM10 treatment inhibited muscle differentiation through the activation of NOTCH1 cleavage. Recombinant ADAMTS1 reversed ADAM10-induced muscle cell atrophy by suppressing NOTCH1 activation and downregulating
