Biologic clocks and the gut

Abstract

The gastrointestinal tract displays biologic rhythms in basal gastric acid output, epithelial cell proliferation, gastrointestinal motility, and appetite regulation. Furthermore, the development of gastrointestinal complications after administration of aspirin and after chemo- and radiotherapy for metastatic colon cancer depends on the time of administration. Biologic rhythms are driven by so-called clock genes. Thus, it is conceivable that subsets of genes in the gastrointestinal tract are under clock gene control as well. The purpose of this article is to discuss basic concepts in the studies of biologic rhythms, to review examples of biologic rhythms in the gastrointestinal tract, and to discuss examples of gastrointestinal diseases in which alterations in biologic rhythms may play a pathogenetic role.
