ADSC‐Exosomes Preserve Mitochondrial Function and Ameliorate Uranyl Acetate‐Induced Nephrotoxicity Through Inhibition of ATF4 and Activation of PGC‐1α/NRF/Tfam Pathway
Uranyl acetate (UA)‐induced renal injury disrupts mitochondrial ultrastructure and homeostasis through oxidative stress‐mediated pathways, with activating transcription factor 4 (ATF4) identified as a critical molecular switch. This study demonstrates ATF4 directly suppresses peroxisome proliferator‐activated receptor...
