- CAII, CAIX, and CAXII all have characteristic expression patterns in esophageal adenocarcinoma (EAC), its precursors and normal squamous epithelium. In EAC, CAII downregulation is associated with metastatic disease. CAIX expression is lost towards the more malignant lesions, but in lymph node positive disease, expression seems to be higher. CAXII is only expressed in normal esophageal epithelium. PMID: 30066203
