However, the expression of IL13Rα2 did not change after the castration of mice in the gene expression profile of pre‐ and post‐castration tumor tissue of KUCaP2,8 indicating that the IL13Rα2 increase during the castration therapy might not contribute to the acquisition of castration‐resistance of prostate cancer. Here, IL13RA2 is linked to prostate carcinoma.
