Humulus lupulus (Hop): Plant Compounds and Activation of Bitter Taste Receptors to Influence Appetite and Fullness in Intestinal Tumor Cells

AI simplified

Abstract

The hop extract is a rich source of bitter compounds that may stimulate hormone secretion to reduce hunger.

  • Bitter compounds in the hop extract primarily include α- and β-acids.
  • Activation of bitter taste receptors (TAS2Rs) in the intestine could enhance the secretion of appetite-reducing hormones such as glucagon-like peptide 1 (GLP-1) and cholecystokinin (CCK).
  • The extract may decrease levels of hunger-related hormones like ghrelin.
  • The secretion of GLP-1 and CCK is associated with calcium signaling pathways activated by TAS2Rs.
  • Inhibition of specific receptors and calcium channels reduces the hormone secretion response to the hop extract.
