Solute carrier family 7 member 11(SLC7A11)is a cysteine transporter located on the cytoplasmic membrane.Its main function is to regulate glutathione(GSH)synthesis,redox maintenance,and tumor growth and metastasis.It is significantly overexpressed in various types of solid tumors and participates in cell ferroptosis and disulfidptosis processes.SLC7A11 has an important impact on the occurrence and development of tumors,im-mune regulation,and regulation of drug reactions,and provides a basis for improving most current clinical treat-ment plans for tumors.
