We found that the expression of CDH4 is higher in cholangiocarcinoma (CHOL), Colon adenocarcinoma (CAOD), KIRP (Kidney renal papillary cell carcinoma), KIRC (Kidney renal clear cell carcinoma), THCA (Thyroid carcinoma) and HNSCC than normal tissues adjacent to the cancer. Here, CDH4 is linked to cholangiocarcinoma.
