Withaferin A Enhances Mitochondrial Biogenesis and BNIP3-Mediated Mitophagy to Promote Rapid Adaptation to Extreme Hypoxia.
    Cells, 2022, 12-25, Volume: 12, Issue:1

    Rapid adaptation to extreme hypoxia is a challenging problem, and there is no effective scheme to achieve rapid adaptation to extreme hypoxia. In this study, we found that withaferin A (WA) can significantly reduce myocardial damage, maintain cardiac function, and improve survival in rats in extremely hypoxic environments. Mechanistically, WA protects against extreme hypoxia by affecting BCL2-interacting protein 3 (BNIP3)-mediated mitophagy and the peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α)-mediated mitochondrial biogenesis pathway among mitochondrial quality control mechanisms. On the one hand, enhanced mitophagy eliminates hypoxia-damaged mitochondria and prevents the induction of apoptosis; on the other hand, enhanced mitochondrial biogenesis can supplement functional mitochondria and maintain mitochondrial respiration to ensure mitochondrial ATP production under acute extreme hypoxia. Our study shows that WA can be used as an effective drug to improve tolerance to extreme hypoxia.
