Function
Produced by macrophages, IFN-alpha have antiviral activities. Interferon stimulates the production of two enzymes: a protein kinase and an oligoadenylate synthetase.

Phospholipid hydroperoxide glutathione peroxidase (GPX4) [Suppressor]
In total 1 item(s) under this target
Experiment 1 Reporting the Ferroptosis Target of This Regulator [1]
Target for Ferroptosis Suppressor
Responsed Disease Systemic lupus erythematosus ICD-11: 4A40
Pathway Response Fatty acid metabolism hsa01212
Ferroptosis hsa04216
Cell Process Cell ferroptosis
In Vitro Model
hPBMCs (Human peripheral blood mononuclear cells)
In Vivo Model
In ferroptosis rescue experiments, LPX-1 (10 mg/kg), CTX (20 mg/kg) or 0.1 ml DMSO (10%) was administered intraperitoneally to female MRL/Mpj and MRL/lpr mice every other day for six weeks beginning at 12 weeks of age. Urine was collected in the morning once a week. Mice were sacrificed at 18 weeks of age, and spleen, kidneys, lymph nodes, and peripheral blood were collected for analysis. For in vivo treatment, MRL/lprmice were administered 0.1 ml DMSO (10%), Cl-amidine (20 mg/kg), LPX-1 (10 mg/kg), or Cl-amidine (20 mg/kg) combined with LPX-1 (10 mg/kg) intraperitoneally every other day for 3 weeks starting at 12 weeks of age.

Response regulation IFN- (IFNA1, IFNA2, IFNA4, IFNA5, IFNA6, IFNA7, IFNA8, IFNA10, IFNA13, IFNA14, IFNA16, IFNA17, IFNA21) and SLE IgG suppresses the transcription of GPX4 by promoting binding of CREM to the Gpx4 promoter. Together, neutrophil ferroptosis is an important driver of neutropenia in systemic lupus erythematosus (SLE) and heavily contributes to disease manifestations.
