Abstract:
Depleting glutathione by xCT inhibition induces iron-dependent ferroptotic cell death, which is suppressed by lipophilic antioxidants. We screened food extracts with xCTKO-MEFs, identifying garlic extracts as particularly potent in inhibiting ferroptosis among the food extracts examined in this study. xCTKO-MEFs can serve as a convenient tool for identifying food extracts that are effective in inhibiting ferroptosis.
Insights
Garlic extracts effectively inhibit ferroptosis, a cell death pathway triggered by glutathione depletion. Researchers used genetically modified mouse cells to screen food extracts, finding garlic to be a potent suppressor of this cell death mechanism.
Area of Science:
- Biochemistry
- Cell Biology
- Nutritional Science
Background:
- Glutathione depletion via xCT inhibition triggers iron-dependent ferroptotic cell death.
- Lipophilic antioxidants are known to suppress ferroptosis.
Purpose of the Study:
- To screen food extracts for their potential to inhibit ferroptosis.
- To identify natural compounds that can modulate ferroptosis.
Main Methods:
- Utilized xCT knockout mouse embryonic fibroblasts (xCTKO-MEFs) for screening.
- Assessed the inhibitory effects of various food extracts on ferroptosis induction.
Main Results:
- Garlic extracts demonstrated significant potency in inhibiting ferroptosis among tested food extracts.
- xCTKO-MEFs proved to be a valuable tool for identifying ferroptosis inhibitors.
Conclusions:
- Garlic extracts possess ferroptosis-inhibitory properties.
- The use of xCTKO-MEFs facilitates the discovery of natural ferroptosis suppressors.
