To explore the potential mechanisms by which STMN1 promotes the malignant behaviors of ICC cells, we divided the cholangiocarcinoma patients in The Cancer Genome Atlas database into STMN1 high‐expression group (top 25%) and STMN1 low‐expression group (bottom 25%) according to their STMN1 expression levels. The gene discussed is STMN1; the disease is cholangiocarcinoma.
