We found that with the use of immunoblotting, annexin A1 was expressed by multiple cancer cell lines, with more prominent band intensity observed for colon cancer cell lines (MC38, HT-29, HCT116, LoVo) compared with pancreatic (Pan02) or lung (LLC) cancer cells (Fig. 5A). The gene discussed is ANXA1; the disease is malignant colon neoplasm.
