Ferroptosis represents a newly programmed cell death, and the process is usually accompanied with iron-dependent lipid peroxidation. Importantly, ferroptosis is implicated in a myriad of diseases. Recent literature suggests a potential position of ferroptosis in the pathogenesis of metabolic dysfunction-associated fatty liver disease (MAFLD), the most widespread liver ailment worldwide. Intriguingly, several functional genes and metabolic pathways central to ferroptosis are regulated by nuclear factor erythroid-derived 2-like 2 (NRF2). In current work, we aim to identify protocatechuic acid (PCA), a primary metabolite of antioxidant polyphenols, as a potent NRF2 activator and ferroptosis inhibitor in the hepatic lipotoxicity and steatosis models. Herein, both NRF2^+/+ and NRF2^−/− cell lines and mice were used to analyze the importance of NRF2 in PCA function, and hepatic lipotoxicity and steatosis models were induced by palmitic acid and high-fat diet respectively. Our results indicated that ferroptosis was mitigated by PCA intervention in hepatic cells. Furthermore, PCA exhibited therapeutic efficacy against ferroptosis, as well as hepatic lipotoxicity and steatosis. The protective role of PCA was predominantly mediated through NRF2 activation, potentially elucidating a pivotal mechanism underlying PCA's therapeutic impact on MAFLD. Additionally, the augmented mitochondrial TCA cycle activity observed in hepatic lipotoxicity and steatosis models was ameliorated by PCA, in part via NRF2-dependent pathways, further bolstering PCA's anti-ferroptosis properties. Collectively, our findings underscore PCA’s potential in alleviating hepatic ferroptosis, lipotoxicity and steatosis via inducing activation of NRF2 signaling pathway, offering a promising strategy for the therapy of MAFLD as well as related lipid metabolic disorders.
