- Gastrointestinal hormones play a crucial role in maintaining intestinal homeostasis and regulating processes like digestion, absorption, and excretion, primarily acting through G-protein-coupled receptors.
- Recent research indicated that lacking Gα/Gα signaling negatively impacts the maturation of Paneth cells, leading to their differentiation into goblet cells and affecting colonic mucosa regeneration in colitis models.
- In experiments with an intestinal epithelial cell line, manipulating Gα/Gα levels showed that overexpression inhibited cell growth, while downregulation promoted it, hinting at a potential role of Gα/Gα signaling in regulating enterocyte functions like absorption or secretion.
