WebSubsequently, the levels of reactive oxygen species, malondialdehyde, GPX4, SLC7A11 and Nrf2, which are indicators of ferroptosis, were measured by a dihydroethidium fluorescent dye probe ... WebApr 13, 2024 · GPX4 and SLC7A11 are the central regulators of ferroptosis. GPX4 and SLC7A11 have the definite role in maintaining intracellular glutathione levels, which reduce the degree of ferroptosis-associated oxidative stress damage. Then, we selected 25 h post-LPS as the time point and evaluated the intracellular iron using FerroOrange staining.

In addition to killing tumor cells via ROS, IR can directly damage cellular DNA and produce double-strand breaks.
WebJun 16, 2024 · In the presence of GSH, glutathione peroxidase 4 (GPX4) mediates the conversion of toxic lipid peroxides to nontoxic lipid alcohols [ 27 ]. SLC7A11 inhibition results in GSH depletion which in turn downregulates GPX4, leading to cellular/subcellular membrane damage caused by accumulation of iron-dependent lipid peroxides [ 28 ]. WebMar 3, 2024 · It has been identified that the inhibition of ferroptosis can enhance cancer progression, and ferroptosis plays a crucial role in breast cancer development [6–8]. However, the molecular mechanism of the ferroptosis process in breast cancer progression remains elusive.
WebApr 23, 2024 · The main mechanism of ferroptosis is depletion of glutathione and decrease of GPX4 activity, lipid oxides cannot be metabolized through glutathione reductase reaction catalyzed by GPX4, and then iron (II) ion oxidizes lipid to produce reactive oxygen species (ROS), thus promoting cell death.
