Table 1. Summaries for the function of 10 hub genes.

No. Gene symbol Full name Function
1 CLCA4 Chloride channel accessory 4 May be involved in mediating calcium-activated chloride conductance
2 GUCA2A Guanylate cyclase activator 2A Endogenous activator of intestinal guanylate cyclase. It stimulates this enzyme through the same receptor binding region as the heat-stable enterotoxins
3 GCG Glucagon Regulates blood glucose by increasing gluconeogenesis and decreasing glycolysis. GLP-1 is a potent stimulator of glucose-dependent insulin release. GLP-2 stimulates intestinal growth, concomitant with increased crypt cell proliferation
4 SST Somatostatin Somatostatin inhibits the release of somatotropin. This hormone is an important regulator of the endocrine system through its interactions with pituitary growth hormone, thyroid stimulating hormone, and most hormones of the gastrointestinal tract
5 MS4A12 Membrane spanning 4-domains A12 May be involved in signal transduction as a component of a multimeric receptor complex. Silencing of this gene in colon cancer cells inhibits the proliferation, cell motility, and chemotactic invasion of cells
6 PLP1 Proteolipid protein 1 This is the major myelin protein from the central nervous system. It plays an important role in the formation or maintenance of the multilamellar structure of myelin
7 CHGA Chromogranin A This gene product is a precursor to three biologically active peptides; vasostatin, pancreastatin, and parastatin
8 PYY Peptide YY This gut peptide inhibits exocrine pancreatic secretion, has a vasoconstrictory action, and inhibitis jejunal and colonic mobility
9 VIP Vasoactive intestinal peptide VIP causes vasodilation, lowers arterial blood pressure, stimulates myocardial contractility, increases glycogenolysis and relaxes the smooth muscle of trachea, stomach and gallbladder
10 GUCA2B Guanylate cyclase activator 2B May be a potent physiological regulator of intestinal fluid and electrolyte transport. May be an autocrine/paracrine regulator of intestinal salt and water transport
