1979), whereas IEC‐Cdx2L1 cells represent differentiated IECs (Suh and Traber 1996). Caco‐2 cells were derived from colon cancer cells. Consistent with observations in mucosal tissue, all three lines of IECs also expressed 14‐3‐3ζ and HuR proteins (Fig. 1B). Here, ELAVL1 is linked to malignant colon neoplasm.
