Site-directed mutagenesis Mutant forms of mito GCL refractory to the shRNA against GCL ( mito GCLmut) or catalytically inactive mito GCL ( mito GCL (E103A)) were generated using the site-directed mutagenesis QuikChange XL kit (Stratagene, La Jolla, CA, USA), followed by Dpn I digestion
Glutathione inhibits tyrosinase by binding to copper at the enzymes active sites, directly reducing melanin synthesis capacity
Notably, differential susceptibility to ferroptosis exists between cell types: endometriotic cells acquire resistance through upregulation of GPx4 and GSH, whereas granulosa cells remain vulnerable due to decreased antioxidant defenses (35, 36)
In China, about 400 million people are affected by 2024, and the prevalence of MASLD is as high as 29.2%, making it the largest liver disease
