Abstract

PLC-β exerts biologic influences through GPCR. GPCRs are involved in regulating glucose-stimulated insulin secretion (GSIS). Previous studies have suggested that PLC-βs might play an important role in pancreatic β cells. However, because of a lack of the specific inhibitors of PLC-β isozymes and appropriate genetic models, the in vivo function of specific PLC-β isozymes in pancreatic β cells and their physiologic relevance in the regulation of insulin secretion have not been studied so far. The present study showed that PLC-β1 was crucial for β-cell function by generation of each PLC-β conditional knockout mouse. Mice lacking PLC-β1 in β cells exhibited a marked defect in GSIS, leading to glucose intolerance. In ex vivo studies, the secreted insulin level and Ca 2+ response in Plcb1 f/f ; pancreas/duodenum homeobox protein 1 ( Pdx1 )-Cre recombinase-estrogen receptor T2 ( CreERt2 ) islets was lower than those in the Plcb1 f/f islets under the high-glucose condition. PLC-β1 led to potentiate insulin secretion via stimulation of particular G q -protein-coupled receptors. Plcb1 f/f ; Pdx1-CreERt2 mice fed a high-fat diet developed more severe glucose intolerance because of a defect in insulin secretion. The present study identified PLC-β1 as an important molecule that regulates β cell insulin secretion and can be considered a candidate for therapeutic intervention in diabetes mellitus.-Hwang, H.-J., Yang, Y.

  • PLCβ1 has been implicated in control of neuronal function and enhancement of glucose-stimulated insulin secretion in pancreatic β-cells downstream of specific GPCRs.

    “Among many roles, ubiquitously expressed PLCβ1 enzyme has been implicated in control of neuronal function and the enhancement of glucose-stimulated insulin secretion in pancreatic β-cells downstream of specific GPCRs in these different cell types [36–40].”

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.
