Gegen Qinlian Decoction (GQD) alleviates hepatic endoplasmic reticulum stress-induced unfolded protein response and apoptosis, increases intracellular calcium ion levels, downregulates phosphorylated JNK (p-JNK), activates the IRS1/PI3K/Akt signaling pathway, improves insulin sensitivity, and regulates hepatic glycogen metabolism both in vivo and in vitro (Wang et al., 2020)

et al., 2022), Meanwhile, a study has also confirmed that berberine promotes the secretion of GLP-1 by L cell in intestinal tissue, while activating GLP-1R and the phosphorylation of PKA through endocrine pathways (Sun S
Wild-type mice treated with GIPR-Ab/GLP-1 and CNS GIPR KO mice exhibit similar changes in gene expression related to tissue remodelling, lipid metabolism and inflammation in white adipose tissue and liver
