Ferroptosis Guide

What is Ferroptosis?

“Ferroptosis” was coined by Stockwell et al. at Columbia University in 2012 and described as a form of iron-dependent cell death. * It was reported to be a form of programmed cell death by the Nomenclature Committee on Cell Death (NCCD) in 2018.
Ferroptosis is a form of programmed cell death that is caused by iron ion-dependent accumulation of lipid peroxides. Ferroptosis has been shown to follow a different cell death pathway from apoptosis and thus is attracting attention as a new target for cancer therapy. It has also been found to be associated with various diseases, such as neurodegenerative diseases, cerebral apoplexy, and hepatitis (NASH).

How Does Ferroptosis Cause Cell Death?

Ferroptosis is characterized by the accumulation of lipid peroxides. Lipid peroxides are formed from oxidation of polyunsaturated fatty acids (PUFA) in membrane phospholipids, with iron suggested to be involved. Intracellular glutathione peroxidase 4 (GPX4) uses reduced glutathione (GSH), an antioxidant, to reduce lipid peroxides generated by reactive oxygen species (ROS).*
However, when lipid peroxides accumulate due to GPX4 disruption or GSH depletion, ferroptosis is triggered.

*Stockwell et al, a leading researcher in the field of ferroptosis, summarized inhibitors, inducers, and detection indicators of ferroptosis in the following review, in which Dojindo’s Liperfluo is introduced for detection of lipid peroxides.

Induction of Ferroptosis by Erastin?

Erastin is a known inducer of ferroptosis. By inhibiting the cystine transporter (xCT), erastin inhibits the uptake of cystine. Cystine is the raw material for GSH. Therefore, Erastin ultimately decreases the amount of GSH. Decreased GSH then results in lipid peroxide accumulation and induction of ferroptosis.
The following experimental examples show changes in each aforementioned index as a consequence of erastin stimulation. Measurements are made using Dojindo reagents.

Using erastin-treated A549 cells, we measured intracellular Fe2+, ROS, lipid peroxide, glutathione, glutamate release into the extracellular space, and cystine uptake. As a result, inhibition of xCT by elastin was observed and also the release of glutamate and uptake of cystine were decreased. Furthermore, elastin treatment decreased intracellular glutathione while it increased intracellular Fe2+ , ROS, and lipid peroxides.

Nonalcoholic steatohepatitis (NASH)

Suppression of hepatitis via ferroptosis

In a study involving the livers of NASH model mice, it was confirmed that necrosis precedes apoptosis in the development of fatty liver. Further experiments showed that ferroptosis is involved within necrosis as a trigger for steatohepatitis and that inhibition of ferroptosis almost completely suppressed the onset of hepatitis.

Neurodegenerative disease

Confirmation of the link between lysosomal disorders and ferroptosis

In experiments using human neurons, it is reported that knockdown of the lysosomal protein prosaposin induces formation of lipofuscin, a hallmark of aging. This process involves the iron-catalyzed generation of reactive oxygen species, leading to induction of ferroptosis.

Regulation of cancer immunity via ferroptosis

CD8+ T cells activated by immunotherapy were found to confer an anti-tumor effect by promoting lipid peroxidation and inducing ferroptosis. The mechanism of immunotherapy-induced inhibition of cystine uptake and promotion of lipid peroxidation in tumor cells is discussed.
