TRIM28: A Novel E3 Ubiquitin Ligase Guarding the Heart Against Ischemia/Reperfusion-Induced Ferroptosis

TRIM28: A Novel E3 Ubiquitin Ligase Guarding the Heart Against Ischemia/Reperfusion-Induced Ferroptosis

New research identifies TRIM28 as a critical E3 ubiquitin ligase that degrades IRP2, thereby suppressing iron uptake and preventing myocardial ferroptosis during ischemia/reperfusion injury. This pathway, activated by p55γ and the drug perhexiline, offers a promising therapeutic target for patients with ischemic heart disease.
