摘要：SummaryGLP-1 analogs are a class of glucose-lowering agents with multiple benefits in diabetes, but its role in adipose tissues remains to be elucidated. The aim of this study was to determine the action of recombinant human GLP-1 (rhGLP-1) Beinaglutide (BN) in the insulin sensitivity and lipid metabolism of adipose tissues. We have shown that, after BN injection, obese mice displayed lower body weight, fat mass, and plasma lipid levels. In addition, BN promoted the insulin sensitivity in the white adipose tissues. Furthermore, we have found that the BN treatment caused significant changes in content and composition of different lipid classes, including glycerolipids, glycerophospholipids, and sphingolipids, as well as expression of genes in lipid metabolic pathways in the adipose tissues. Taken together, our data demonstrate that BN could resist HFD-induced obesity by targeting the composition of major lipid classes and the expression of genes in lipid metabolism of adipose tissues.Graphical abstractDisplay OmittedHighlights•Recombinant human GLP-1 Beinaglutide (BN) reduces high-fat-diet-induced obesity•BN increases insulin sensitivity of adipocytesin vivoandin vitro•BN alters lipidomic and transcriptomic profiles in adipose tissues of obese mice•BN promotes thermogenic gene expression in adipose tissuesMolecular physiology; Cell biology; Lipidomics
