glutathione peroxidase metal (GPx) mutants exhibit susceptibility to Glutathione Peroxidase - Proteases -

These cells did not grow in medium without any glutathione (0 M) but they grew in media with very small amounts of glutathione (i.e., more than 0.25 M of extracellular glutathione)

The primary mechanisms through which BPC-157 promotes tissue repair include activation of the VEGFR2 signaling pathway for angiogenesis (new blood vessel formation), FAK-paxillin pathway activation that enhances cell migration to injury sites, upregulation of growth hormone receptors that amplify proliferative signals, and selective modulation of nitric oxide systems that balance beneficial vasodilation against inflammatory damage
