Stress-Coping Phenotypes Shape Adipose Tissue Function and Plasticity and Modulate Metabolic Resilience

ABSTRACT: This study investigated how stress-coping phenotypes (stress-resilient Dominant and stress-vulnerable Submissive mice) shape white adipose tissue (WAT) function under standard and high-fat diet (HFD) conditions. Metabolic, molecular, and transcriptomic analyses were performed on epididymal (eWAT) and inguinal (iWAT) white adipose tissue. Results revealed that stress-vulnerable mice exhibit impaired adipogenesis, adipocyte hypertrophy, unfavorable adipokine profiles, and defective insulin signaling in WAT under HFD. Transcriptomic profiling by RNA-seq identified adipogenesis, fatty acid metabolism, and oxidative phosphorylation as differentially regulated pathways between the strains. Functional analyses confirmed reduced proliferative and adipogenic potential of stromal vascular fraction (SVF) cells from stress-vulnerable mice. Pharmacological activation of PPARgamma (pioglitazone) improved adipogenesis and metabolic parameters, while antidepressant treatment (paroxetine) normalized behavioral deficits and improved adipogenic capacity in stress-vulnerable mice.

Sox9-Meis1 inactivation is required for adipogenesis, advancing Pref-1+ to PDGFRa+ cells [GFP+ RNA-Seq]

Project description:Adipocytes arise from commitment and differentiation of adipose precursors in white adipose tissue (WAT). In studying adipogenesis, precursor markers, including Pref-1 and PDGFRα, are used to isolate precursors from stromal vascular fraction of WAT, but the relationship among the markers is not known. Here, we used Pref-1 promoter-rtTA system in mice for labeling Pref-1+ cells and for inducible inactivation of Pref-1 target, Sox9. We show requirement of Sox9 for maintenance of Pref-1+ proliferative, early precursors. Upon Sox9 inactivation, these Pref-1+ cells become PDGFRa+ cells that express early adipogenic markers. Thus, we show for the first time that Pref-1+ cells precede PDGFRa+ cells in the adipogenic pathway and that Sox9 inactivation is required for WAT growth and expansion. Furthermore, we show that, in maintaining early adipose precursors, Sox9 activates Meis1 which prevents adipogenic differentiation. Our study also demonstrates the Pref-1 promoter-rtTA system for inducible gene inactivation in early adipose precursor population.

White adipose tissue resident macrophages are required for adipogenesis and energy storage.

Project description:White adipose tissue (WAT) stores energy in the form of lipids. WAT macrophages cause adipose tissue inflammation and insulin resistance when intake exceeds expenditures, but their contribution to homeostasis remain poorly understood. Here, we show that two populations, ã and ä, of TNF-producing bone marrow-derived monocytic cells are transiently recruited to damaged adipocytes and mediate insulin resistance. In contrast, we identify α/β yolk-sac derived resident macrophages that produce adipogenic growth factors, and form a niche required for adipogenesis as white adipocytes do not differentiate in their absence. Production of adipogenic growth factors by α/β macrophages increases with lipid storage, but they do not contribute to inflammation. Thus the molecular identities and functions of resident macrophages and BM-derived cells are specified by their lineage rather than diet variation. These results identify an essential function of WAT resident macrophages in adipogenesis and energy homeostasis, separate from inflammation mediated by the recruitment of inflammatory leukocytes.

Identification of CD44 downstream target genes

Project description:CD44 expression has been shown to be enhanced in the liver and white adipose tissue (WAT) during obesity, suggesting a possible regulatory role for CD44 in metabolic syndrome. To study this hypothesis, we compared the gene expression profiles in liver and in WAT between WT and CD44 knockout (CD44KO) mice fed a high-fat diet (HFD) for 21 weeks. This analysis demonstrated that several genes associated with triglyceride synthesis and accumulation, including Mogat2, Cidea, Cidea, Apoa4, and Elovl7, were decreased in the livers of CD44KO mice compared to WT mice. Many genes encoding pro-inflammatory chemokines and chemokine receptors also were decreased in the livers of CD44KO mice. Analysis with WAT showed that genes associated with triglyceride accumulation, including Fasn, Elovl6 and Mogat2, were increased in WAT of CD44KO(HFD) mice compared to WT(HFD) mice. Moreover, many genes associated with inflammation, including cytokines (Cxcl14, Cxcl12, Il33, and Il2), cytokine receptors (Ccr1, Il6ra, Il10rb), trypases (Tpsb2, Tpsab1, Tpsg1), and cellular matrix proteins (Integrin ?4 (Itga4), ItgaM, Itgb2), were decreased in WAT of CD44(HFD) compared to WT(HFD) mice. This study indicates that CD44 plays a critical role in regulating several aspects of metabolic syndrome. Liver and white adipose tissue (WAT) total RNAs were purified from 5 WT and 5 CD44 knockout mice fed with a high-fat diet for 21 weeks. Then, samples were applied on Agilent mouse genome chips.

EP3 deletion in macrophages aggravates diet-induced obesity in mice by suppressing SPARC

Project description:Macrophages are primary immune cells involved in obesity-triggered chronic low-grade inflammation in adipose tissues. Prostaglandin (PG) E2, mainly generated from macrophages, can regulate adipose tissue remodeling. Here, we observed that PGE2 receptor subtype 3 (EP3) was remarkably downregulated in adipose tissue macrophages from high-fat diet (HFD)-fed mice and patients with obesity. Notably, macrophage-specific deletion of EP3 exacerbated HFD-induced obesity in mice, whereas EP3α isoform overexpression in macrophages alleviated obesity phenotype in HFD-fed mice. EP3 deficiency suppressed anti-adipogenic secreted protein acidic and rich in cysteine (SPARC) secretion in macrophages. SPARC deletion in macrophages abrogated the protection of EP3α-overexpression against HFD-induced obesity in mice. Mechanistically, EP3 activation promoted SPARC expression by suppressing DNA methylation in macrophages through the PKA/Sp1/Dnmt1/3a signaling cascade. EP3 agonist treatment ameliorates HFD-induced obesity in mice. Thus, EP3 inhibits adipogenesis through promoting macrophage releasing SPARC and may serve as a therapeutic target for managing diet-induced obesity.

DEPTOR cell-autonomously promotes adipogenesis and associates with obesity

Project description:An understanding of the mechanisms regulating white adipose tissue (WAT) formation is key for developing of new tools to treat obesity and its related diseases. Here, we identify DEPTOR as a positive regulator of adipogenesis whose expression is associated with obesity. In a polygenic mouse model of obesity/leanness, Deptor is part of the Fob3a QTL linked to obesity and we fine that Deptor is the highest priority candidate gene regulating WAT accumulation in this model. Using a doxycycline-inducible mouse model for Deptor overexpression, we confirmed that Deptor promotes WAT expansion in vivo. DEPTOR expression is elevated in WAT of obese humans and strongly correlates with the degree of obesity. We show that DEPTOR is induced during adipogenesis and that its overexpression cell-autonomously promotes, while its suppression blocks, adipogenesis. DEPTOR positively regulates adipogenesis by promoting the activity of the pro-adipogenic factors Akt/PKB and PPAR-gamma. These results establish DEPTOR as a physiological regulator of adipogenesis and provide new insights into the molecular mechanisms controlling WAT formation. 2 groups of F2 mice for opossing genotype at Fob3a QTL (FF versus VV) - parental strains of the F2 cross were the Fat line and congenic V-line; 5 biological replications per group; reference for Fat line: Horvat S. et al.

Adipocyte thyroid hormone receptor β determines the intracellular usage and fate of glucose and governs systemic homeostasis

Project description:To investigate the effect of thyroid hormone and its receptor on glucose and lipid metabolism in white adipose tissue (WAT), and the effect of thyroid hormone and its receptor on WAT regulation on glucose metabolism and obesity. We constructed mice with adipose tissue-specific knockout of thyroid hormone receptor beta（ATRβKO mice）. ATRβKO mice were given T3 stimulation or high-fat feeding. We then performed gene expression profiling analysis using data obtained from RNA-seq of White adipose tissue from knockout ATRβKO mice treated with T3 or HFD feeding.
