Insulinotropic hormone glucagon-like peptide-I(7-37) stimulation of proinsulin gene expression and proinsulin biosynthesis in insulinoma beta TC-1 cells

Fehmann, H. C.·1992·Endocrinology

Abstract

Glucagon-like peptide-I(7-37) [GLP-I(7-37)] is an intestinal peptide hormone that is released in response to oral nutrients and that potently augments glucose-mediated insulin secretion. GLP-I(7-37) has potent insulin-releasing activities in vivo in response to oral nutrients, in situ in the isolated perfused pancreas, and in vitro in cultured pancreatic B-cells. As such GLP-I(7-37) is a potent hormonal mediator in the enteroinsular axis involved in the regulation of glucose homeostasis. We now show that in addition to stimulating the release of insulin, GLP-I(7-37) stimulates proinsulin gene expression at the levels of gene transcription and cellular levels of proinsulin messenger RNA as well as the translational biosynthesis of proinsulin. These findings of the positive anabolic actions of GLP-I(7-37) on the synthesis of insulin in B-cells support the notion that GLP-I(7-37) may be of therapeutic use in stimulating the production of insulin in patients with noninsulin-dependent diabetes mellitus and that overproduction of insulin with subsequent hypoglycemia will not occur in response to the administration of GLP-I(7-37). Furthermore, these positive actions of GLP-I(7-37) on insulin production obviate the possibility of B-cell exhaustion in response to such a potent secretagogue.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
