In this study, we evaluated the activation of various insulin signaling molecules in human fat in vivo and compared signaling reactions in visceral and subcutaneous fat depots. Paired abdominal omental and subcutaneous fat biopsies were obtained from nonobese subjects with normal insulin sensitivity under basal conditions and 6 and 30 min following administration of intravenous insulin. Insulin...
Glucocorticoid excess increases fat mass, preferentially within omental depots; yet circulating cortisol concentrations are normal in most patients with metabolic syndrome (MS). At a pre-receptor level, 11b-hydroxysteroid dehydrogenase type 1 (11b-HSD1) activates cortisol from cortisone locally within adipose tissue, and inhibition of 11b-HSD1 in liver and adipose tissue has been proposed as a ...
OBJECTIVES It has been proposed that the contribution of nucleoside-analogue reverse transcriptase inhibitor (NRTI) therapy to subcutaneous fat wasting involves adipose tissue-specific mitochondrial DNA toxicity. We have investigated the relationships between NRTI therapy, adipocyte mitochondrial DNA content, evidence of toxicity in adipose tissue and fat wasting in Caucasian male Western Austr...
Differentiation of adipocytes and osteocytes from human adipose and placental mesenchymal stem cells
Objective(s):Mesenchymal stem cells (MSC) can be isolated from adult tissues such as adipose tissue and other sources. Among these sources, adipose tissue (because of easy access) and placenta (due to its immunomodulatory properties, in addition to other useful properties), have attracted more attention in terms of research. The isolation and comparison of MSC from these two sources provides a ...
OBJECTIVE Visceral obesity increases risk of insulin resistance and type 2 diabetes. This may partly be due to a region-specific resistance to insulin's antilipolytic effect in visceral adipocytes. We investigated whether adipose tissue releases the vascular peptide endothelin-1 (ET-1) and whether ET-1 could account for regional differences in lipolysis. RESEARCH DESIGN AND METHODS One group ...
An increase in fat mass associated with obesity results from recruitment and differentiation of adipocyte progenitor cells. The precise origin of these cells is unknown, although accumulating evidence suggests that circulating stem cells can differentiate into cells of mesenchymal lineage. It is currently unclear whether a progenitor adipocyte population exists in circulation. One potential can...
OBJECTIVE In rodents and humans, besides brown adipose tissue (BAT), islands of thermogenic adipocytes, termed "brite" (brown-in-white) or beige adipocytes, emerge within white adipose tissue (WAT) after cold exposure or β3-adrenoceptor stimulation, which may protect from obesity and associated diseases. microRNAs are novel modulators of adipose tissue development and function. The purpose of t...
Fat depots vary in size, function, and potential contribution to disease. Since fat tissue turns over throughout life, preadipocyte characteristics could contribute to this regional variation. To address whether preadipocytes from different depots are distinct, we produced preadipocyte strains from single abdominal subcutaneous, mesenteric, and omental human preadipocytes by stably expressing h...
