Effect of chronic amylase inhibition on pancreatic growth and acinar cell secretory function in rats.

abstract：OBJECTIVES:Glucagon-like peptide-1 (GLP-1) is known to stimulate glucose-dependent insulin production and secretion by pancreatic beta-cells. Preliminary evidence suggests that GLP-1 may also influence endocrine differentiation from pancreatic progenitor cells. Additionally, TGF-beta signaling can also control endocrin...
