Mel is a pineal hormone with lipophilic properties, allowing it to easily cross cell membranes and exert antioxidant effects through both direct and indirect mechanisms.39 Previous studies have reported that melatonin not only scavenges ROS directly but also enhances the expression of antioxidant enzymes such as SOD, CAT, and GSH-Px, thereby providing indirect antioxidant defense.17,40 Melatonin is an indoleamine with notable antioxidant properties, making it a promising agent to counteract inflammatory and neoplastic processes and to manage transplantation outcomes.18,41 However, despite strong evidence from animal studies supporting its antioxidant mechanisms, the clinical applications of melatonin in reproductive medicine are still quite limited in the literature.18,19 Similarly, GSH is an endogenous antioxidant capable of neutralizing free radicals and supporting the GSH-dependent peroxidase system
(Alpha-Tocopherol) metabolism and nutrition in chronic kidney disease
Other functions of GSH include: (i) maintaining the essential thiol status of cysteine residues on proteins
Ovarian morphology evaluation The left ovary was fixed in 10% neutral formalin for 72 hours, treated with ethanol, and then embedded in paraffin blocks for histological examinations
EM data acquisition Immediately before preparing the cryo-EM grids, 2 mM fluorinated Fos-Choline-8 (Anatrace) was added to the purified sample to prevent the protein from being damaged by the hydrophobic airwater interface on a cryo-EM grid
