Pea protein hydrolysate stimulates GLP-1 secretion in NCI-H716 cells via simultaneously activating sensing receptors CaSR and PepT1

Glucagon-like peptide-1 (GLP-1) plays a crucial role in regulating glucose homeostasis by stimulating insulin secretion and suppressing glucagon release. Our previous study observed that pea protein hydrolysate (PPH) exhibited the function of triggering GLP-1 secretion. However, the underlying mechanisms have not been revealed. Herein, the mechanisms of PPH-stimulated GLP-1 secretion were investigated in NCI-H716 cells. The PPH-induced GLP-1 secretion was reduced (
