Guanylate cyclase-C (GC-C) functional overlap with numerous symptoms found in GI disorders. Research on various GI disorders has elucidated the importance of the GC-C receptor and the physiological pathways in which it is involved. Dysregulation of the GC-C–cGMP signalling axis has been associated with dysfunction in the mucosal barrier (eg, UC); fluid and electrolyte balance and pH regulation (eg, chronic idiopathic constipation, IBS with constipation); and epithelial cell proliferation, migration, differentiation and apoptosis (eg, colorectal cancer). These pathways contribute to the abdominal symptoms and/or inflammation involved in GI diseases.
