Thus, the development of interventions that slow the underlying biological processes of aging could have beneficial effects on the prevention or progression of these diseases. To evaluate such geroprotective interventions, quantifying biological damage via aging clocks\u2014particularly those based on transcriptomic biomarkers\u2014has become highly relevant, as they provide estimations with strong biological interpretability. However, the limited availability of transcriptomic clocks for murine experimental models has hindered the implementation of these tools in aging research and their use in evaluating interventions that may have geroprotective effects. Here, we have developed an accurate, accessible, and ready\u2010to\u2010use murine transcriptomic clock that provides robust age predictions for healthy mice using hepatic RNA\u2010seq data. Applying the clock to accelerated\u2010aging models revealed an increased transcriptomic age in progeroid syndromes, demonstrating its ability to capture aging\u2010related biological processes. Finally, considering the main interest of these tools, we show that well\u2010established interventions with geroprotective potential, both genetic (Snell Dwarf, Ames Dwarf, and growth hormone receptor\u2010deficient mice) and environmental (caloric, protein, or methionine restriction, as well as rapamycin supplementation in specific contexts), reduce the transcriptomic age estimated by the clock. These findings indicate that the proposed transcriptomic clock could be a valuable tool for studying the biology of aging and for designing and evaluating potential geroprotective interventions.<\/jats:p>","DOI":"10.1111\/acel.70677","type":"journal-article","created":{"date-parts":[[2026,8,22]],"date-time":"2026-08-22T03:15:24Z","timestamp":1787368524000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["<scp>LivAge<\/scp>\n                    : An Online Aging Clock for Murine Transcriptomic Age Estimation"],"prefix":"10.1111","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-1435-472X","authenticated-orcid":false,"given":"V\u00edctor","family":"Celem\u00edn\u2010Capaldi","sequence":"first","affiliation":[{"name":"Departamento de Bioqu\u00edmica y Biolog\u00eda Molecular Instituto Universitario de Oncolog\u00eda (IUOPA), Universidad de Oviedo  Oviedo Spain"},{"name":"Instituto de Investigaci\u00f3n Sanitaria del Principado de Asturias, ISPA  Oviedo Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-6243-2259","authenticated-orcid":false,"given":"Guillermina","family":"Bea","sequence":"additional","affiliation":[{"name":"Departamento de Bioqu\u00edmica y Biolog\u00eda Molecular Instituto Universitario de Oncolog\u00eda (IUOPA), Universidad de Oviedo  Oviedo Spain"},{"name":"Instituto de Investigaci\u00f3n Sanitaria del Principado de Asturias, ISPA  Oviedo Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9131-6155","authenticated-orcid":false,"given":"David","family":"Roiz\u2010Valle","sequence":"additional","affiliation":[{"name":"Departamento de Bioqu\u00edmica y Biolog\u00eda Molecular Instituto Universitario de Oncolog\u00eda (IUOPA), Universidad de Oviedo  Oviedo Spain"},{"name":"Instituto de Investigaci\u00f3n Sanitaria del Principado de Asturias, ISPA  Oviedo Spain"},{"name":"Centro de Investigaci\u00f3n Biom\u00e9dica en Red de C\u00e1ncer (CIBERONC)  Madrid Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2522-0627","authenticated-orcid":false,"given":"Alejandro P.","family":"Ugalde","sequence":"additional","affiliation":[{"name":"Departamento de Bioqu\u00edmica y Biolog\u00eda Molecular Instituto Universitario de Oncolog\u00eda (IUOPA), Universidad de Oviedo  Oviedo Spain"},{"name":"Instituto de Investigaci\u00f3n Sanitaria del Principado de Asturias, ISPA  Oviedo Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7452-2536","authenticated-orcid":false,"given":"Clea","family":"B\u00e1rcena","sequence":"additional","affiliation":[{"name":"Departamento de Bioqu\u00edmica y Biolog\u00eda Molecular Instituto Universitario de Oncolog\u00eda (IUOPA), Universidad de Oviedo  Oviedo Spain"},{"name":"Instituto de Investigaci\u00f3n Sanitaria del Principado de Asturias, ISPA  Oviedo Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7793-6291","authenticated-orcid":false,"given":"Pedro M.","family":"Quir\u00f3s","sequence":"additional","affiliation":[{"name":"Departamento de Bioqu\u00edmica y Biolog\u00eda Molecular Instituto Universitario de Oncolog\u00eda (IUOPA), Universidad de Oviedo  Oviedo Spain"},{"name":"Instituto de Investigaci\u00f3n Sanitaria del Principado de Asturias, ISPA  Oviedo Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4688-8266","authenticated-orcid":false,"given":"Jos\u00e9 M.
