Here, we report that the cellular plasticity transcription factors ZEB1 and ZEB2 modulate in opposing directions the adaptive antioxidant response to fasting in skeletal muscle. Using transgenic mice in which\n                    <jats:italic>Zeb1<\/jats:italic>\n                    or\n                    <jats:italic>Zeb2<\/jats:italic>\n                    were specifically deleted in skeletal myofibers, we show that in fasted mice, the deletion of\n                    <jats:italic>Zeb1<\/jats:italic>\n                    , but not\n                    <jats:italic>Zeb2<\/jats:italic>\n                    , increased ROS production and that the adaptive antioxidant response to fasting essentially requires ZEB1 and is inhibited by ZEB2. ZEB1 expression increased in fasted muscles and protected them from atrophy; conversely, ZEB2 expression in muscles decreased during fasting and exacerbated muscle atrophy. In fasted muscles, ZEB1 reduces mitochondrial damage and increases mitochondrial respiratory activity; meanwhile, ZEB2 did the opposite. Treatment of fasting mice with\n                    <jats:italic>Zeb1<\/jats:italic>\n                    -deficient myofibers with the antioxidant triterpenoid 1[2-cyano-3,12-dioxool-eana-1,9(11)-dien-28-oyl] trifluoro-ethylamide (CDDO-TFEA) completely reversed their altered phenotype to that observed in fasted control mice. These results set ZEB factors as potential therapeutic targets to modulate the adaptive antioxidant response in physiopathological conditions and diseases caused by redox imbalance.\n                  <\/jats:p>","DOI":"10.1073\/pnas.2301120120","type":"journal-article","created":{"date-parts":[[2023,11,10]],"date-time":"2023-11-10T14:32:37Z","timestamp":1699626757000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":5,"title":["The adaptive antioxidant response during fasting-induced muscle atrophy is oppositely regulated by ZEB1 and ZEB2"],"prefix":"10.1073","volume":"120","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5745-6119","authenticated-orcid":false,"given":"Chiara","family":"Ninfali","sequence":"first","affiliation":[{"name":"Group of Gene Regulation in Stem Cells, Cell Plasticity, Differentiation, and Cancer, Institute of Biomedical Research August Pi Sunyer (IDIBAPS), Barcelona 08036, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9313-1194","authenticated-orcid":false,"given":"Marlies","family":"Cort\u00e9s","sequence":"additional","affiliation":[{"name":"Group of Gene Regulation in Stem Cells, Cell Plasticity, Differentiation, and Cancer, Institute of Biomedical Research August Pi Sunyer (IDIBAPS), Barcelona 08036, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2745-6505","authenticated-orcid":false,"given":"M.
