Tissue-level dissection of obesity-exercise axis in adipose-muscle tissues

ABSTRACT: We studied the opposing effects of exercise training and high-fat diet at tissue-level resolution to reveal gene expression and pathway changes in subcutaneous white adipose tissue, visceral white adipose tissue, and skeletal muscle. We revealed gene modules consistently up-regulated by exercise training, which include fatty acid biosynthesis/beta-oxidation/metabolism, oxidative phosphorylation, TCA cycle, and ROS response. Modules down-regulated by exercise training in all three tissues are antigen presentation, neutrophil degranulation, immune cell migration, phagosome-related genes, ECM-related genes, proliferation, and ribonucleotide biosynthesis. Taken together, exercise training improves fatty acid metabolism and cellular respiration similarly across the three metabolic tissues, and represses immune, ECM, proliferation and tissue-specific pathways.

Exercise Training Remodels Inguinal White Adipose Tissue Through Adaptations in Innervation, Vascularization and the Extracellular Matrix

Project description:Inguinal white adipose tissue (iWAT) is essential for the beneficial effects of exercise training on metabolic health. The underlying mechanisms for these effects are not fully understood and here, we test the hypothesis that exercise training results in a more favorable iWAT structural phenotype. Using biochemical, imaging, and multi-omics analyses we find that 11-days of wheel running in male mice causes profound iWAT remodeling including decreased extracellular matrix (ECM) deposition, increased vascularization and innervation. We identify adipose stem cells as one of the main contributors to training-induced ECM remodeling, show that the PRDM16 transcriptional complex is necessary for iWAT remodeling and beiging, and discover neuronal growth regulator 1 (NEGR1) as a link between PRDM16 and neuritogenesis. Moreover, we find that training causes a shift from hypertrophic to insulin-sensitive adipocyte subpopulations. Exercise training leads to remarkable adaptations to iWAT structure and cell-type composition that can confer beneficial changes in tissue metabolism.

A Novel Role for Subcutaneous Adipose Tissue in Exercise-Induced Improvements in Glucose Homeostasis.

Project description:Exercise training improves whole body glucose homeostasis through effects largely attributed to adaptations in skeletal muscle; however, training also affects other tissues including adipose tissue. To determine if exercise-induced adaptations to adipose tissue contribute to training-induced improvements in glucose homeostasis, subcutaneous white adipose tissue (scWAT) from trained or sedentary donor mice was transplanted into the visceral cavity of sedentary recipients. Remarkably, nine days post-transplantation, mice receiving trained scWAT had improved glucose tolerance and enhanced insulin sensitivity compared to mice transplanted with sedentary scWAT or sham-treated mice. Mice transplanted with trained scWAT had increased insulin-stimulated glucose uptake in tibialis anterior and soleus muscles and brown adipose tissue, suggesting that the transplanted scWAT exerted endocrine effects. Furthermore, the deleterious effects of high-fat feeding on glucose tolerance and insulin sensitivity were completely reversed if high-fat fed recipient mice were transplanted with trained scWAT. In additional experiments, voluntary exercise training by wheel running for only 11 days resulted in profound changes in scWAT including increased expression of ∼1550 genes involved in numerous cellular functions, including metabolism. Exercise training causes adaptations to scWAT that elicit metabolic improvements in other tissues, demonstrating a previously unrecognized role for adipose tissue in the beneficial effects of exercise on systemic glucose homeostasis.

Single-cell dissection of obesity-exercise axis in adipose-muscle tissues

Project description:We studied the opposing effects of exercise training and high-fat diet at single-cell resolution to reveal changes in cell type abundance, cell-type-specific gene expression/pathway/regulatory network changes, and changes in cell-cell communication both within and across tissues. We profiled scRNA-seq in 204,883 cells, grouped into 53 distinct cell sub-types/states across 22 major cell types, from subcutaneous white adipose tissue, visceral white adipose tissue, and skeletal muscle across 16 lean and 15 obese mice with both diet and exercise interventions. Changes in both cell proportion and transcriptional state were most strongly pronounced in adipose stem cells in fat, consistent with roles of adipogenesis in thermogenesis-vs-lipogenesis and hyperplasia-vs-hypertrophy in obesity. For immune cells, exercise training decreases obesity-associated inflammatory tissue-resident cell populations, including myeloid and regulatory T cells, and promotes beige-cell-inducing populations, including NKT cells. These changes clustered in common pathways across tissues for both exercise and obesity, including extracellular matrix remodelling and circadian rhythm in mesenchymal stem cells and cell activation/migration in immune cells.

High-fat diet decreases expression of genes controlling lipid metabolism, mitochondrial function and skeletal system development in adipose tissue, along with increased expression of extracellular matrix remodeling- and inflammation-related genes

Project description:We identified differentially expressed genes in epididymal white adipose tissue of high fat diet(HFD)-fed mice compared to low fat diet-fed mice using microarray analysis. Microarray analysis revealed that genes related to lipolysis, fatty acid metabolism, mitochondrial energy transduction, oxidation-reduction, insulin sensitivity, and skeletal system development were downregulated in HFD-fed mice, and genes associated with extracellular matrix (ECM) components, ECM remodeling, and inflammation were upregulated. The top 10 up- or downregulated genes include Acsm3, mt-Nd6, Fam13a, Cyp2e1, Rgs1, and Gpnmb, whose roles in obesity-associated adipose tissue deterioration are poorly understood. Total RNA of epididymal white adipose tissue was obtained from low fat diet (10 kcal% fat)- and high fat diet(45 kcal% fat)-fed mice and mRNA expression was measured using microarray analysis.
