  • Resumen

  • BUFFALO, NY- August 27, 2024 – A new #research perspective was #published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science), Volume 16, Issue 15 on July 25, 2024, entitled, “Trioxidized cysteine and aging: a molecular binomial that extends far beyond classical proteinopathic paradigms.” Oxidative stress (OS) - characterized by an imbalance between oxidants and antioxidants - leads to the formation of oxidative posttranslational modifications (PTMs), including those involving cysteine (Cys) residues in aging proteomes. Specifically, the formation of trioxidized Cys (t-Cys) results in permanent protein damage. Recent findings in rodents have revealed that irregular regulation of t-Cys residues in the aging proteome disrupts homeostatic phosphorylation signaling, leading to alterations in proteins similar to those caused by phosphorylated serine (p-Ser) residues. In this perspective, researchers José Antonio Sánchez Milán, María Mulet, Aida Serra and Xavier Gallart-Palau from University Hospital Arnau de Vilanova (HUAV) and University of Lleida (UdL), present novel data, validating the increase of specific t-Cys sites associated with aging in a blood-related circulating human proteome. "The scope and findings included here support the hypothesis that t-Cys residues may serve as important mechanistic and biological markers, warranting further exploration in the context of unhealthy aging and age-related major diseases.” DOI - https://doi.org/10.18632/aging.206036 Corresponding authors - Aida Serra - aida.serra@udl.cat, and Xavier Gallart-Palau - xgallart@irblleida.cat Video short - https://www.youtube.com/watch?v=roO_8WMGak8 Sign up for free Altmetric alerts about this article - https://aging.altmetric.com/details/email_updates?id=10.18632%2Faging.206036 Subscribe for free publication alerts from Aging - https://www.aging-us.com/subscribe-to-toc-alerts Keywords - aging, oxidative stress, unhealthy aging, t-Cys, aging diseases, aging proteome About Aging-US The mission of the journal is to understand the mechanisms surrounding aging and age-related diseases, including cancer as the main cause of death in the modern aged population. The journal aims to promote 1) treatment of age-related diseases by slowing down aging, 2) validation of anti-aging drugs by treating age-related diseases, and 3) prevention of cancer by inhibiting aging. (Cancer and COVID-19 are age-related diseases.)
