Intestinal Alteration of Α-Gustducin and Sweet Taste Signaling Pathway in Metabolic Diseases is Partly Rescued after Weight Loss and Diabetes Remission

Our data highlighted 1) the sweet taste transduction pathway in EECs plays pivotal role for glucose homeostasis at least at gene expression level; 2) metabolic disorders led to altered gene expression of sweet taste signaling pathway in intestine contributing to impaired GLP-1 secretion; and 3) after surgical intestinal modifications, increased expression of α-gustducin contributed to metabolic improvement.
