Rejuvenating muscle stem cells with the glutathione system

Glutathione biosynthesis involves two adenosine triphosphate-dependent steps: • First, γ-glutamylcysteine is synthesized from L-glutamate and cysteine. This conversion requires the enzyme glutamate–cysteine ligase (GCL, glutamate cysteine synthase). This reaction is the rate-limiting step in glutathione synthesis. • Second, glycine is added to the C-terminal of γ-glutamylcysteine. This condensation is catalyzed by glutathione synthetase.

"WebCu-BTC and Cu-BDC MOFs also exhibit the ability to consume GSH and produce ROS due to the presence of copper ions. As an important intracellular reducing substance, GSH eliminates ROS and reduces the therapeutic effect of ROS-related therapies. In this regard, Cu-BTC MOF was integrated with photosensitizers to enhance PDT by depleting GSH. " - Gsh synthesis
