But as we age, glutathione production falters
"Glutathione metabolism and its selective modification"
These properties may also improve the appearance of post-procedure skin texture and enhance skin recovery upon topical application to affected areas after complete healing
A 2014 mouse study found that NAC and vitamin E accelerated lung tumor progression and reduced survival.41 A 2015 melanoma mouse study found that NAC increased lymph node metastases in mice with malignant melanoma.42 A 2019 mouse study reported that NAC protected against emphysema-related lung damage but also induced lung adenocarcinoma in some mice.43 And a 2021 hepatocellular carcinoma study found that antioxidant supplements including NAC promoted tumor formation, growth, and drug resistance in experimental models by reducing intracellular ROS.3 Newer human data add another layer of complexity
Finally, we highlight future perspectives, including the integration of novel biomarkers from metabolomics and proteomics, the application of artificial intelligence in building sophisticated prediction models, and the design of marker-guided precision intervention trials
The ratio of reduced glutathione to glutathione disulfide has been shown to be critical in cell survival, this system is very tightly regulated
