The SLC7A11 (Solute Carrier Family 7 Member 11) gene belongs to the solute transport family and encodes a heteromeric, sodium-independent and highly specific cystine/glutamate xCT transporter, which is believed to be involved in regulating ferroptosis in the diseases characterized by iron deposition and reactive oxygen species production, such as ischemia/reperfusion-induced acute lung injury and cardiomyopathies (19–21). The gene discussed is SLC7A11; the disease is injury.
