TLDR The gene NM_026333 slows down aging by affecting the NCX1 pathway and could be targeted for anti-aging treatments.
The study identified NM_026333 as a novel anti-aging gene that was downregulated in CF6-overexpressing transgenic and high salt-fed mice, which experienced proton-induced aging. The NM_026333 protein, consisting of 269 amino acids, rescued cells from aging hallmarks by binding to NCX1 and suppressing its reverse mode, preventing proton-induced epigenetic changes and autophagy impairments. Additionally, an NCX1 inhibitor extended the lifespan of transgenic mice, suggesting that targeting the NCX1 pathway could be a potential anti-aging therapy.
