Glucose metabolism and insulin sensitivity of isolated human adipose tissue was studied as a function of adipose cell size and number. Glucose metabolism by these tissues was closely related to the number of cells in the fragment, irrespective of cell size. Adipose cells of obese individuals metabolized glucose to carbon dioxide and triglyceride at rates similar to adipose cells of nonobese sub...
Apolipoprotein E (apoE) is a multifunctional protein that is highly expressed in human and murine adipose tissue. Endogenous adipocyte apoE expression influences adipocyte triglyceride turnover and modulates the expression of genes involved in lipid synthesis and oxidation. We now demonstrate the regulation of adipose tissue apoE expression by nutritional status in lean and obese mice. Obesity ...
BACKGROUND: Fat-tailed sheep breeds have a unique ability to tolerate periods of negative energy balance due to seasonal changes in feed availability. This ability is attributed to presence of fat-tail as a body energy reserve, however the exact underlying mechanisms controlling the response of adipose tissue depots to variations in energy balance in fat-tailed breeds a...
Obesity alters adipose tissue metabolic and endocrine function and leads to an increased release of fatty acids, hormones, and proinflammatory molecules that contribute to obesity associated complications. To further characterize the changes that occur in adipose tissue with increasing adiposity, we profiled transcript expression in perigonadal adipose tissue from groups of mice in which adipos...
Expansion of visceral adipose tissue correlates with the metabolic syndrome and increased cardiovascular risk. Hypertrophied visceral fat becomes inflamed, causing increased lipolysis, decreased triglyceride storage, and lipotoxicity in skeletal muscle and liver resulting in insulin resistance. Perivascular adipose tissue is a normal component of the adventitia of arteries in humans and animals...
The adipose tissue is a central metabolic organ in the regulation of whole-body energy homeostasis. The white adipose tissue functions as a key energy reservoir for other organs, whereas the brown adipose tissue accumulates lipids for cold-induced adaptive thermogenesis. Adipose tissues secrete various hormones, cytokines, and metabolites (termed as adipokines) that control systemic energy bala...
Obesity is strongly associated with metabolic syndrome. Recent research suggests that excess adipose tissue plays an important role in development of the syndrome. On the other hand, persons with a deficiency of adipose tissue (e.g. lipodystrophy) also manifest the metabolic syndrome. In some animal models, expansion of adipose tissue pools mitigates adverse metabolic components (e.g. insulin r...
OBJECTIVE Metabolic heterogeneity among obese individuals may be attributable to differences in adipose cell size. We sought to clarify this by quantifying adipose cell size distribution, body fat, and insulin-mediated glucose uptake in overweight to moderately-obese individuals. METHODS A total of 148 healthy nondiabetic subjects with BMI 25-38 kg/m2 underwent subcutaneous adipose tissue bio...
Numerous regulatory T cells (Tregs) are present in adipose tissues compared with other lymphoid or non-lymphoid tissues. Adipose Tregs regulate inflammatory state and insulin sensitivity. However, the mechanism that maintains Tregs in adipose tissue remains unclear. Here, we revealed the contribution of adipose tissue macrophages (ATMs) to the induction and proliferation of adipose Tregs. ATMs ...
Adipose tissue plays an important role in energy metabolism and related diseases. The content of intramuscular fat significantly influences the pork quality. In this study, the whole gene expression of dorsal subcutaneous (s.c.) adipose tissue and intramuscular (i.m.) adipose tissue isolated from longissimus dorsi muscle tissue were compared using Affymetrix Gene-Chip microarray technology. The...
