(Submitter supplied) Background: Excessive white adipose tissue (WAT) expansion as in obesity is generally associated with chronic inflammation of WAT, which contributes to obesity associated complications. Low oxygen availability in WAT is hypothesized to be the initiator of this inflammatory response. Hypothesis: We examined the hypothesis that local tissue hypoxia is responsible for the initiation of inflammation in WAT. more...

(Submitter supplied) Mice have their lowest (basal) metabolic rate when housed at thermoneutrality, which starts above 29 degrees C. Although they eat less, and thus reduce their energy intake, their energy balance remains positive leading to an increased adiposity, especially when fed a high fat diet. However, almost all metabolic mouse studies are performed at standard room temperatures ranging between 20 and 22 degrees C. more...

(Submitter supplied) Metabolic dysfunction of white adipose tissue (WAT) is considered to be underlying the comorbidities in obesity, including insulin resistance and tissue inflammation. Moreover, due to the expansion of WAT, local tissue hypoxia has been reported. Whether local tissue hypoxia underlies the metabolic de-arrangements and is the first step in initiation inflammation is questioned here. Desferrioxamine (DFO) is a chemical compound trapping free iron, thus leading to a reduction in oxygen availability within the body, which mimics hypoxia. more...

(Submitter supplied) Human adipose tissue derived stem cells were differentiated to adipocytes in vitro. At the end of differentiation, cells were treated with siRNA targeting CD248 followed by exposure to 1% oxygen levels. Microarray analysis were performed to identify differentially regulated genes.

(Submitter supplied) Time-course analysis of adipocyte gene expression profiles response to high fat diet. The hypothesis tested in the present study was that in diet-induced obesity, early activation of TLR-mediated inflammatory signaling cascades by CD antigen genes, leads to increased expression of pro-inflammatory cytokines and chemokines, resulting in chronic low-grade inflammation. Early changes in collagen genes may trigger the accumulation of ECM components, promoting fibrosis in the later stages of diet-induced obesity. more...

Analysis of epididymal and mesenteric white adipose tissues (WAT) of mice fed a high fat diet for up to 24 weeks. Excessive fat accumulation was evident in visceral WAT depots after 4 weeks. Results provide insight into the molecular events that occur during the development of diet-induced obesity.

(Submitter supplied) Obesity is a risk factor for numerous metabolic disorders; however, not all obese individuals are prone to insulin resistance. The central aim of this study was to identify molecular pathways directly related to insulin resistance independent of BMI in obesity. We sought to determine the gene expression signature of adipose tissue in a body mass index (BMI)-matched obese cohort of patients that are either insulin sensitive or insulin resistant.

(Submitter supplied) Investigation of whole genome gene expression level changes in GW501516 (a Ppard ligand) or Il-4 treated Ppard-overexpressing RAW 264.7 macrophages as compared to vehicle. Alternative activation of adipose tissue resident macrophages inhibits obesity-induced metabolic inflammation. In the current study we profile genes regulated by two M2 inducers, Il-4 or Ppard agonists and find that alternative activation promotes the cell survival program, while inhibiting that of inflammation-related cell death.

(Submitter supplied) Overweight is a growing health problem worldwide. The most effective strategy to reduce weight is energy restriction (ER): restriction of food intake without malnutrition. ER has been shown to be beneficial in disease prevention, healthy aging, and inflammation. Recent studies suggest that reducing the protein content of a diet contributes to the beneficial effects by ER. The first objective of our study was to assess the effect of energy restriction on changes in gene expression in adipose tissue. more...

(Submitter supplied) This SuperSeries is related to a manuscript published in Genome Biology. The abstract of this manuscript follows here: Background Investigations performed in mice and humans have acknowledged obesity as a low-grade inflammatory disease. Several molecular mechanisms have been convincingly involved in activating inflammatory processes and altering cell composition in white adipose tissue (WAT); however, the overall importance of these alterations, and their long-term impact on the metabolic functions of the WAT and on its morphology, remain unclear. more...

(Submitter supplied) Extracellular matrix (ECM) remodelling occurs during tissue repair and inflammation-related pathologies with deposition of specific proteins. White adipose tissue (WAT) was recently shown to be the site of substantial interstitial fibrosis. ECM components, such as fibronectin, and their receptors integrins control cell migration, proliferation and differentiation. Adipocyte differentiation which is under the control of a specific transcriptional network is associated with decrease of fibronectin-rich matrix. more...

(Submitter supplied) Metabolic disorders, such as obesity and type 2 diabetes, are major public health concerns worldwide. Dietary interventions, such as tea consumption, have been suggested as an effective strategy to prevent and treat metabolic disorders. White adipose tissue, as the main energy storage organ in mammals, plays a critical role in the regulation of whole-body metabolism. Recent studies have shown that the microenvironmental cell composition and metabolic network of white adipose tissue can be modulated by dietary factors, including tea consumption. more...

(Submitter supplied) Skeletal muscle is the largest tissue in the body and mainly relies on mitochondrial oxidative metabolism for sustainable ATP production. Reduced oxygen availability, also known as hypoxia, can be caused by high altitude or pathology and impacts mitochondria. Whereas long-term hypoxia results in increased reliance on glycolysis, reduced fatty acid oxidation and a decreased skeletal muscle mass, the in vivo mechanisms of adaptation of skeletal muscle to acute hypoxia remain elusive. more...

(Submitter supplied) Distinct markers for early, mild vitamin B3 deficiency are lacking. To identify these, we examined the molecular responses of white adipose tissue to vitamin B3 withdrawal. We performed a dietary intervention in male C57Bl/6JRcc mice. A diet with a low but adequate level of tryptophan without nicotinamide riboside (NR) was compared to the same diet with NR at the recommended vitamin B3 (30 mg NR per kg diet). more...
