Abstract: Food deprivation protects against ischemia-reperfusion (IR) injury through unknown mechanisms. In an experimental rat model of acute IR injury, we found that preoperative fasting for 3 days protects rats from tubular damage and renal functional decline by increasing antioxidant protection independently of the NF-E2-related factor 2 (Nrf2), and by maintaining mitochondrial morphology and function. In addition, further analysis revealed that fasting protects against tubulointerstitial fibrosis. In summary, our results point out to fasting as a robust nutritional intervention to limit oxidative stress and mitochondrial dysfunction in early acute kidney injury and also to promote long-term protection against fibrosis. β€’ Keywords: Fasting, Oxidative stress, Mitochondrial dysfunction, Fibrosis, Ischemia-reperfusion injury, Acute kidney injury, Chronic kidney disease β€’ Bioblast editor: Plangger M β€’ O2k-Network Lab: MX Mexico City Pedraza Chaverri J
