demonstrated that IFN‐γ can inhibit the system Xc− expression on tumour cells via enhancing STAT1/IRF1 signalling and inducing the STAT1 abundance on the promoter region of SLC7A11, one subunit of system Xc−, thus impairing cystine intake and inducing tumour ferroptosis.136. Here, IRF1 is linked to neoplasm.
