To determine the potential cytokines responsible for GSTO1 induction in bladder cancer, HT1376 was treated with individual cytokines, including GRO‐α, GM‐CSF, M‐CSF, MIP‐1β, IL‐1α, IL‐1β, IL‐2, IL‐6, IL‐18, SDF‐1α, TNF‐α, and VEGF‐A. The gene discussed is CXCL1; the disease is urinary bladder carcinoma.
