The effect of dietary vitamin E on renal tissue damage and lipid peroxidation was investigated following treatment with ferric nitrilotriacetate (Fe-NTA) in rats. Almost 100% renal proximal tubular necrosis was observed in the vitamin E-deficient rats following Fe-NTA treatment (5 mgFe/kg body wt, ip) as early as 12 hr. In the vitamin E-supplemented rats, no injury was observed in the proximal convoluted (cortical) tubules, although some injury was seen in the medullary outer stripe (mostly pars recta of the proximal tubules) 24 hr after Fe-NTA treatment. The tissue lipid peroxidation was dose-dependently increased 1 hr after a single ip injection of Fe-NTA (1 to 10 mg Fe/kg body wt). Vitamin E-deficient animals had an increased tissue content of thiobarbituric acid-reactive substance following Fe-NTA treatment, whereas vitamin E-supplemented animals showed suppressed lipid peroxidation. This study indicates that vitamin E provides some protection against the nephrotoxicity and associated lipid peroxidation induced by Fe-NTA.

Colorectal cancer (CRC) is one of the most prevalent and deadly malignancies worldwide. Recently, ferroptosis, a novel form of regulated cell death characterized by iron dependency and lipid peroxidation, has garnered significant attention from researchers. The mechanisms underlying ferroptosis, including intracellular iron levels, lipid peroxidation, and antioxidant system regulation, offer new insights into cancer treatment strategies.

Ferroptosis is a newly discovered form of cell death that is influenced by iron levels and is triggered by cellular metabolism and excessive lipid peroxidation. Epigenetic regulation plays a crucial role in the development and progression of diseases, making it essential to understand these mechanisms in order to identify potential targets for drug development and clinical treatment. The intersection of ferroptosis and epigenetics has opened up new avenues for research in drug development, offering innovative strategies for combating diseases.

The accumulation of lipids in hepatocytes in nonalcoholic fatty liver disease (NAFLD) leads to an increase in reactive oxygen species and changes in the intracellular microenvironment, while ferroptosis is the result of the accumulation of iron-dependent lipid peroxidation. Studies have shown that ferroptosis plays an important role in the pathogenesis of NAFLD. Herein, we have developed a viscosity-sensitive fluorescence probe PTSO with near-infrared emission and a large Stokes shift, which were achieved by introducing the sulfone group into the dioxothiochromen-malononitrile fluorophore as an electron-withdrawing group.
