MEGALIN DEFICIENCY EXACERBATES RENAL FIBROSIS DURING THE AKI-TO-CKD TRANSITION AFTER ISCHEMIA–REPERFUSION INJURY VIA THE SELENOPROTEIN P–GPX4–FERROPTOSIS AXIS
(ISN-WCN 2026)
- "For instance, megalin deficiency attenuates kidney injury in models of rhabdomyolysis-induced AKI and drug-induced nephrotoxicity (e.g., vancomycin), whereas it exacerbates renal injury in models of hemolysis-induced AKI and western diet-induced tubulointerstitial nephritis. Regarding ischemia–reperfusion injury (IRI), megalin mRNA expression decreases 24 hours after IRI and recovers by 96 hours; however, its pathophysiological role during the AKI phase and the AKI-to-CKD transition remains unclear.Methods To elucidate the role of megalin in the AKI and AKI-to-CKD transition after IRI, we used male C57BL/6 mice and tamoxifen-inducible PTEC-specific megalin knockout mice (Megalin fl/fl; Ndrg1-CreERT2; hereafter referred to as iMegKO).First, unilateral IRI (35 min) was performed in C57BL/6 mice to assess the temporal expression and function of megalin...Treatment with the ferroptosis inhibitor liproxstatin-1 or selenium supplementation (sodium selenite) markedly..."

Disruption of iron homeostasis by HERC2-FTL axis leads to chondrocyte loss and exacerbates osteoarthritis.
(PubMed, Apoptosis)
- "ATDC5 chondrocytes were treated with IL-1β or Erastin...In vitro, treatment with the ferroptosis inhibitor Liproxstatin-1 or the HERC2-targeting compound PAC restored redox homeostasis, reduced lipid peroxidation, and improved chondrocyte viability under inflammatory and ferroptosis stress...HERC2 promotes OA progression by activating autophagy-dependent ferroptosis via FTL degradation. Targeting this pathway using ferroptosis inhibitors or HERC2-binding compounds like PAC may offer a promising disease-modifying approach for OA treatment."

The AhR/ROS-mediated lipid peroxidation pathway contributes to 6PPDQ-induced intestine-specific injury in zebrafish during embryonic development.
(PubMed, Fish Shellfish Immunol)
- "In support of this finding, both AhR antagonist CH-223191 and ROS scavenger N-acetylcysteine effectively alleviated 6PPDQ-induced intestinal injury, thereby supporting the critical role of 6PPDQ-triggered AhR/ROS signaling in the event...This notion was further reinforced by findings that lipid peroxidation inhibitors, liproxstatin-1 and ferrostatin-1, successfully ameliorated 6PPDQ-induced intestinal injury phenotypes. In summary, our results revealed that the AhR/ROS-mediated lipid peroxidation pathway contributes to the 6PPDQ-caused intestinal injury in zebrafish during embryonic development. These findings provide novel insights into the intestinal susceptibility of 6PPDQ and highlight its potential risks to the embryonic development of fish."

Nrf2 attenuates diquat-induced renal ferroptosis by regulating mitochondrial ferritin.
(PubMed, Toxicol Mech Methods)
- "The rats were randomly assigned to four experimental groups: control, diquat, diquat + Liproxstatin-1 (Lip-1, a ferroptosis inhibitor), and diquat + Sulforaphane (SFN, an Nrf2 activator)...Immunofluorescence co-localization analysis further revealed co-localization of Nrf2 and FtMt in kidney tissues. In conclusion, these findings demonstrate that Nrf2 activation attenuates diquat-induced renal ferroptosis by modulating FtMt expression, suggesting that they may serve as a potential therapeutic target for preventing diquat-induced kidney injury."

The research progress of ferroptosis in acute lung injury.
(PubMed, Biochem Biophys Rep)
- "Its core molecular machinery, including glutathione peroxidase 4 (GPX4), acyl-CoA synthetase long-chain family member 4 (ACSL4), and the cystine/glutamate antiporter system Xc-, becomes dysregulated across various ALI subtypes, such as sepsis, ischemia-reperfusion, and COVID-19.This review delineates how ferroptosis contributes to ALI through iron overload, uncontrolled lipid peroxidation, and failure of antioxidant defenses, ultimately leading to pulmonary endothelial and epithelial cell death. We further summarize subtype-specific mechanisms and evaluate emerging therapeutic strategies, including ferroptosis inhibitors (e.g., liproxstatin-1), Nrf2 activators, and iron chelators, highlighting their potential for targeted intervention in ALI/ARDS."

Limitations of Ferroptosis Inhibitors on the Doxorubicin-Induced Cardiotoxicity.
(PubMed, Antioxidants (Basel))
- "In both H9c2 cardiomyocyte cell lines and human induced pluripotent stem cell-derived cardiomyocytes, ferrostatin-1 and liproxstatin-1 rescued cell death induced by RSL3, a ferroptosis inducer, but failed to prevent doxorubicin-induced cell death. Finally, doxorubicin-injected mice treated with ferroptosis inhibitors exhibited significantly reduced survival and increased levels of N-terminal pro B-type natriuretic peptide, a biomarker of heart failure. These findings suggest that inhibiting ferroptosis alone is insufficient to mitigate doxorubicin-induced cardiotoxicity."
