    1. in Caco-2 CFTR-shRNA cells, the EGFR ligand EREG is overexpressed due to an active IL-1beta autocrine loop that indirectly activates EGFR, constituting new signaling effectors for the CFTR signaling pathway, downstream of CFTR, Cl(-) , and IL-1beta. PMID: 29091309

    3. Study shows how the EGFR ligands epiregulin (EREG) and epigen (EPGN) stabilize different dimeric conformations of the EGFR extracellular region.
