PANoptosis-related gene signatures are strongly enriched in the renal tubulointerstitial tissue of patients with DKD, serving as a comprehensive indicator of tubulointerstitial injury (209211)
Additionally, supplementing GlyNAC was also closely associated with the hallmarks of aging, including mitochondrial dysfunction, mitochondrial biogenesis, intercellular communication, nutrient sensing, loss of proteostasis, stem-cell exhaustion, genomic damage, cellular senescence, and telomere attrition
The amino acid sequence (Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val) includes an unusual triple proline structure conferring exceptional stability
Glutathione and hallmarks of aging: A study in older adults (n=48, aged 60-80) found that GlyNAC supplementation for 16 weeks improved several molecular hallmarks of aging, including mitophagy, nutrient sensing (reduced mTOR activation, increased AMPK signaling), inflammation (reduced NF-kB activation), and genomic instability (reduced 8-OHdG), alongside increased telomerase activity (Kumar et al., Aging, 2023) [31]
It first connects the gamma-carboxyl group of glutamic acid to the amino group of cysteine to form the precursor of GSH, gamma-glutamylcysteine
