Lens for enrichment and network studies analysis of altered expression of messenger RNA (mRNA) in ileal biopsies of healthy controls and patients with constipation-predominant irritable bowel syndrome (IBS-C) and diarrhea-predominant irritable bowel syndrome (IBS-D). Note in the left panel the connectivity of mechanisms involved in ion absorption or secretion (particularly, solute carrier family 9 member A1 and PATJ [also known as inactivation-no-afterpotential D-like) as well as the unconnected downregulated G-protein–coupled bile acid receptor 1 (GPBAR1) in IBS-C. The right panel shows connectivity for the increased mRNA expression related to barrier function, as well as cell development, kinetics, and repair. CALR, calreticulin; CLDN, claudin; CTNNB1, catenin beta 1; FN1, fibronectin 1; KITLG, KIT ligand; MYLK, myosin light chain kinase; PPP1CB, protein phosphatase 1 catalytic subunit beta; SOS1, Sons of Sevenless (Drosophila) homolog 1; TFF1, trefoil factor 1; TJP1, tight junction protein 1; TLR, toll-like receptor.
