Recombinant ADAMTS‑1 promotes muscle regeneration accompanied by downregulation of Notch signaling.

ABSTRACT: Skeletal muscle satellite cells (MuSCs) play a central role in muscle regeneration; however, their capacity declines with age, contributing to sarcopenia. A disintegrin and metalloproteinase with thrombospondin motifs‑1 (ADAMTS‑1) regulates MuSC activation and differentiation. The present study aimed to investigate the potential of recombinant ADAMTS‑1 (rADAMTS‑1) as a therapeutic strategy to enhance MuSC proliferation and improve regeneration. After barium chloride injection, mice received daily intraperitoneal injections of rADAMTS‑1 at 5 or 10 mg/kg for 1, 3, 7, or 14 days to monitor recovery. Primary skeletal muscle and C2C12 cells were also treated with rADAMTS‑1 to evaluate its effects on gene and protein expression during proliferation and differentiation in vitro. The number
