Targeting KLF4 Degradation by Doxycycline Restores Peroxisome Lipid Metabolism and Mitochondrial Energy Production in Acute Kidney Injury.
It is demonstrated that doxycycline directly binds KLF4 and promotes its ubiquitin-mediated degradation via the E3 ligase FBXO32, which restores ACOX3/IDH2-mediated fatty acid oxidation and the TCA cycle, enhancing cellular resilience against ischemic crisis.
