SOCS2 improves HCC radiotherapy efficacy by promoting the ubiquitin‐mediated degradation of SLC7A11 and increasing ferroptosis.[105] A marked increase in stearoyl‐CoA desaturase 1 (SCD1) expression levels was detected in esophageal squamous cell carcinoma (ESCC), and this elevated expression was deemed a predictor of poor patient prognosis. The gene discussed is SLC7A11; the disease is hepatocellular carcinoma.
