Galanin in humans reduces the levels of plasma insulin.
Galanin in humans reduces the levels of plasma insulin. Correct Answer False
While galanin can inhibit transcription and insulin secretion of the proinsulin gene induced by GIP and GLP1, infusion of galanin in humans has no effect on plasma insulin levels. Galanin also prevents exocrine pancreatic secretion and the movement of intestinal ions, and it causes intestinal smooth muscle contraction and relaxation.
