Dissecting Semaglutide-dependent transcriptome response in obesity and osteoarthritis across tissues at single-cell resolution

ABSTRACT: The clinical observations of semaglutide cannot be fully explained by the classical GLP-1R signaling, indicating that semaglutide may exert its effects through a more complex multi tissue regulatory network. Based on this background, this study utilized high-fat diet (HFD) - induced obesity and surgery induced osteoarthritis (OA) models to simulate metabolic joint complications. By systematically collecting peripheral blood (PB), bone marrow (BM), liver, brain tissue, and skeletal muscle from C57BL/6 mice, and integrating 10x Genomics single-cell transcriptome sequencing, we constructed a cross tissue cell atlas that covers the immune, nervous, and motor metabolic systems under treatment with semaglutide. In addition, we compared the gene expression disturbances in mouse tissues after administration of semaglutide. Through these comparisons, we can more accurately decipher the specific effects of semaglutide treatment on gene expression in mice, thereby gaining a deeper understanding of their mechanisms of action in vivo.

Semaglutide Exacerbates Stunting in Growth-Impaired Juvenile Male Mice via Reduced Energy Metabolism

Project description:Animals rely on linear growth to attain their full adult size. The regulators of this multifactorial process, including environmental and endocrine cues, are still incompletely understood. Notably, GLP-1, glucagon-like peptide 1 (GLP-1) has emerged as a potential player in this process. Here, we employ semaglutide, a pharmaceutical GLP-1R agonist as a tool to mechanistically dissect the interplay between GLP-1 receptor activation, energy metabolism, and linear growth during the juvenile period, independent of its clinical applications. Using a juvenile mouse model, we show that chronic semaglutide treatment lowers blood glucose without affecting food intake or weight gain in juveniles with a normal growth pattern. However, in growth-stunted juveniles, semaglutide treatment exacerbates linear growth impairment through at least 2 concomitant mechanisms: a moderate reduction in food intake, and a decreased catabolic activity incompatible with tissue growth. These data suggest a complex interplay between GLP-1 signaling, energy metabolism, and growth during juvenile development. Overall, these findings highlight the value of semaglutide as a mechanistic tool for understanding how GLP-1 receptor activation modulates growth and metabolism in juveniles, emphasizing the importance of developmental context for interpreting its effects.

The hepatoprotective benefits of semaglutide in MASH require the intrahepatic endothelial GLP-1 receptor

Project description:GLP-1 receptor agonists such as semaglutide improve metabolic dysfunction-associated liver disease (MASLD), yet the hepatic cell types mediating these effects remain unclear. GLP-1R expression in the liver is restricted to non-parenchymal cells, but its detection by conventional single-cell RNA sequencing is limited due to low transcript abundance. We performed GEM-X Flex-seq (10x Genomics) single-cell RNA sequencing on liver single-cell suspensions from wild-type C57BL/6J mice fed a standard chow diet, a choline-deficient high-fat diet (CDHFD), or CDHFD with semaglutide treatment. This dataset enables cell type-resolved mapping of Glp1r expression across the hepatic niche and characterization of transcriptomic changes associated with semaglutide treatment, revealing pericentral liver sinusoidal endothelial cells (LSECs) as direct targets mediating weight loss-independent improvements in hepatic inflammation, fibrosis, and immune remodeling.

Effects of semaglutide on the gut microbiota of high-fat diet-fed mice lacking GLP-1Rs in T cells

Project description:Gut intraepithelial lymphocytes (IELs) are one of the few immune cell populations in the body that expresses glucagon-like 1 receptors (GLP-1R). To test the potential effects of GLP-1 on the gut microbiota through the gut IEL GLP-1R, we performed 16s rRNA seq on the DNA isolated from the fecal pellet of Lck-Cre; Glp1rfl/fl mice (Glp1rTcell-/-) or controls (Glp1rTcell+/+) fed a high-fat diet (HFD) for 12 weeks followed by 1 week of HFD plus semaglutide (10 ug/kg) or vehicle treatment. Fecal pellets from a group of age-matched, sex-matched control mice were included as a chow control group.

Semaglutide attenuates obesity-induced impact on intestinal epithelium

Project description:Obesity, a complex ailment, has demonstrated promising weight reduction outcomes with glucagon-like peptide-1 receptor agonists (GLP-1RA) drugs like semaglutide. Nevertheless, their intricate mechanisms remain elusive. In this study, we constructed single-cell transcriptomic profiles of intestinal epithelium from individuals with normal and high BMI, revealing significant transcriptomic and metabolic alterations.

BI 456906: a dual glucagon-like peptide-1/glucagon agonist promoting bodyweight reduction

Project description:Glucagon and glucagon-like peptide-1 (GLP-1) are hormones involved in energy homeostasis. GLP-1 receptor (GLP-1R) agonism reduces food intake and delays gastric emptying, and glucagon receptor (GCGR) agonism increases energy expenditure by thermogenesis. BI 456906 is a subcutaneous, once-weekly injectable dual GLP-1R/GCGR agonist in development for the treatment of obesity or non-alcoholic steatohepatitis. Here we show that BI 456906 is a potent dual agonist with an extended half-life in human plasma. Key GLP-1R-mediated mechanisms of reduced food intake, delayed gastric emptying and improved glucose tolerance were confirmed in GLP-1R knockout mice. GCGR activity was confirmed by reduced plasma amino acids, increased hepatic expression of nicotinamide N-methyltransferase and increased energy expenditure. BI 456906 produced greater bodyweight reductions than maximally efficacious semaglutide doses and modulated gene expression, including genes involved in amino acid metabolism. BI 456906 is a potent dual agonist that produces bodyweight-lowering effects through both GLP-1R and GCGR agonism.

Semaglutide targets mitochondria to regulate metabolism and inflammation in sarcopenia and osteoarthritis

Project description:Metabolic and inflammatory diseases often coexist, and become important challenges facing global health. As a traditional anti-obesity drug, semaglutide is reported to have therapeutic effects in sarcopenia and osteoarthritis (OA), but its mechanism of action still needs to be explored. Here we employed single-cell sequencing analysis to analyze transcriptome changes cross various tissues of high-fat diet (HFD) and OA model mice, and found that semaglutide significantly improved the metabolic and inflammatory disorders of muscle tissue during HFD and OA. Mechanistically, we found that semaglutide could enhance muscle mitochondrial metabolism and mitophagy, alleviated the activation of inflammatory cytokines caused by hypoxia, and regulated the progression of sarcopenia and OA across tissues. Intramuscular injection of mitochondria, pre-stimulated by semaglutide, could significantly alleviate OA inflammation and pain symptoms. These findings reveal the mitochondrial regulatory mechanism in the muscle-OA axis and provide a new perspective for the application of semaglutide in OA treatment.

DIO-MASH mice analysed for hepatic gene expression after treatment with semaglutide

Project description:Modulation of metabolic, inflammatory, and fibrotic pathways by semaglutide in metabolic dysfunction-associated steatohepatitis Metabolic dysfunction-associated steatohepatitis (MASH) is a chronic liver disease strongly associated with cardiometabolic risk factors. Semaglutide, a glucagon-like peptide-1 receptor agonist, improves liver histology in MASH, but the underlying signals and pathways driving semaglutide-induced MASH resolution are not well understood. We show that, in two preclinical MASH models, semaglutide improved histological markers of fibrosis and inflammation, and reduced hepatic expression of fibrosis- and inflammation-related gene pathways.

Semaglutide and bariatric surgery induce distinct changes in the composition of mouse white adipose tissue

Project description:Adipose tissue is a central player in energy balance and glucose homeostasis, expanding in the face of caloric overload in order to store energy safely. If caloric overload continues unabated, however, adipose tissue becomes dysfunctional, leading to systemic metabolic compromise in the form of insulin resistance and type 2 diabetes. Changes in adipose tissue during the development of metabolic disease are varied and complex, made all the more so by the heterogeneity of cell types within the tissue. Here we present detailed atlases of murine WAT in the setting of diet-induced obesity, as well as after weight loss induced by either vertical sleeve gastrectomy (VSG) or treatment with the GLP-1 receptor agonist semaglutide. We focus on identifying populations of cells that return to a lean-like phenotype versus those that persist from the obese state, and examine pathways regulated in these cell types across conditions. These data provide a resource for the study of the cell type changes in WAT during weight loss, and paint a clearer picture of the differences between adipose tissue from lean individuals who have never been obese, versus those who have.
