Transcriptomic analysis of the bitter taste receptor-mediated glucagon-like peptide-1 stimulation effect of quinine

다국어 초록 (Multilingual Abstract)

Quinine is a bitter taste receptor agonist that has been studied its anti-pyretic, anti-malarial, antipain,and anti-inflammatory activity. In this study, glucagon-like peptide-1 (GLP-1) stimulation effect of quinine was investigated. Bitter taste receptors are G protein-coupled receptor (GPCR), which transfer the molecular signal through its downstream cascade. The activation of bitter taste receptor, which expressed in the enteroendocrine L cells, stimulates the GLP-1 secretion and therefore can be a therapeutic target of the type-2 diabetes mellitus (T2DM). Here, we studied GLP-1 stimulation effect of quinine on the endocrine differentiated NCI-H716 cells. To investigate the molecular mode-of-action of the GLP-1 stimulation effect of quinine in the enteroendocrine L cells, transcriptomic analysis was performed. Our data suggest that quinine stimulates the GLP-1 secretion through the bitter taste receptor-signaling pathway, and thus has the possibility of therapeutic agent of T2DM.
