Interactions between the body’s internal clock, gut stem cells, and gut lining cell development

The circadian rhythm significantly influences gut physiological processes, particularly the proliferation and differentiation of intestinal epithelial cells.

• Circadian rhythms are crucial for maintaining gut homeostasis and facilitating repair processes.
• Key signaling pathways, including Wnt, Notch, and Hippo, are involved in regulating the interactions between circadian rhythms and cell cycle dynamics.
• Molecules such as BMAL1 and CLOCK play a role in coordinating stem cell functions with circadian rhythms.
• Notch signaling is associated with regulating the cell cycle while interacting with circadian rhythms.
• Hippo-Wnt signaling may balance cell proliferation and differentiation in the gut.
• Casein kinase 1 delta, glycogen synthase kinase 3, and AMP-activated protein kinase are shared enzymes that influence the cell cycle, circadian rhythm, and signaling pathways.
