(Submitter supplied) Objective: Potential regulators of adipogenesis include microRNAs (miRNAs), small non-coding RNAs that have been recently shown related to adiposity and differentially expressed in fat depots. However, to date no study is available regarding the relationship of miRNAs expression profile, biological pathway and cellular phenotype during human adipogenesis. Thereby, the aim of this study was to investigate whether miRNA expression profile in human adipocytes is related to adipogenesis and to test whether miRNA profile in human subcutaneous adipose tissue is associated to human obesity and co-morbidities. more...

(Submitter supplied) MicroRNAs are a class of molecular regulators found to participate in numerous biological processes, including adipogenesis. However, whether dietary changes impact on microRNA (miRNA) in ruminants has not been reported. Therefore, this study aimed to evaluate the dietary effect on miRNA expression in subcutaneous (backfat) and visceral fat depots (perirenal fat) from beef steers fed with different diets containing high or low fat levels. more...

(Submitter supplied) Background/Objectives: Obese subjects have increased number of enlarged fat cells which are reduced in size but not number in post-obesity. We performed DNA methylation profiling in fat cells with the aim of identifying differentially methylated DNA sites (DMS) linked to adipose hyperplasia (many small fat cells) in post-obesity. Subjects/Methods: Genome-wide DNA methylation was analyzed in abdominal subcutaneous fat cells from 16 women examined two years after gastric bypass surgery at a post-obese state (BMI 26±2 kg/m2, mean±s.d.) and 14 never-obese women (BMI 25±2 kg/m2). more...

(Submitter supplied) MicroRNAs (miRNAs) are small non-coding RNAs found to regulate several biological processes including adipogenesis. Understanding adipose tissue regulation is critical for beef cattle as fat is an important determinant of beef quality and nutrient value . This study analyzed the association between genomic context characteristics of miRNAs with their expression and function in bovine adipose tissue. more...

(Submitter supplied) Cancer-associated cachexia (CAC) is a metabolic syndrome characterized by progressive depletion of adipose and muscle tissue which cannot be corrected by conventional nutritional therapy. Adipose tissue, as an important energy storage, could appear obvious loss in early stage of CAC, which becomes a negative factor affecting the quality of life, efficacy of chemotherapy and so on. In order to identify differentially expressed RNAs in adipose tissue of CAC patients with noncachexia patients, we chose three gastric cancer patients with remarkable weight loss as CAC group and three gastric cancer patients without significant weight change within half a year as the control group. more...

(Submitter supplied) Adipose tissue abundance relies partly on the factors that regulate adipogenesis, i.e. proliferation and differentiation of adipocytes. While the transcriptional program that initiates adipogenesis is well-known, the importance of microRNAs in adipogenesis is less well studied. We thus set out to investigate whether miRNAs would be actively modulated during adipogenesis and obesity. Several models exist to study adipogenesis in vitro, of which the cell line 3T3-L1 is probably the most well known, albeit not the most physiologically appropriate. more...

(Submitter supplied) Human bone marrow mesenchymal stromal cells are capable of limited self-renewal and multi-lineage differentiation in vitro. Several studies have demonstrated that microRNAs, post-transcriptional modifiers of protein expression, play crucial roles in the regulation of these complex processes. To gain knowledge regarding the role of microRNAs in human adipocyte regulation, we examined the microRNA expression profile of the immortalized human bone marrow-derived stromal cell line hMSC-Tert20. more...

(Submitter supplied) Low-grade chronic inflammation plays an important role in the development of obesity and obesity-associated disorders such as insulin resistance, type 2 diabetes, the metabolic syndrome and atherosclerosis. One possible link between obesity and inflammation is the enhanced activation of circulating monocytes making them more prone to infiltration into the adipose and vascular tissues of obese persons. more...

Gene expression was measured using Affymetrix microarrays in subcutaneous and omental adipose tissue (n=3 independent subjects; 6 arrays). Predictive bioinformatic algorithms were employed to identify those differentially expressed genes that code for secreted proteins and to identify common pathways between these proteins. more...

(Submitter supplied) In previous studies, multiple animal models (rhesus monkeys, sheep) have suggested a developmental programming effect of PCOS. The goal of this study was to examine whether developmental programming may accompany epigenetic changes by examining intrinsic epigenetic differences, specifically chromatin accessibility, in adipose stem cells (ASCs) from subcutaneous (SC) adipose tissue of PCOS women vs age- and BMI-matched control samples as they mature into adipocytes in vitro.

(Submitter supplied) The adipose tissue is an endocrine regulator and a risk factor for atherosclerosis and cardiovascular disease when by excessive accumulation induces obesity. Although the adipose tissue is also a reservoir for stem cells (ASC) their function and “stemcellness” has been questioned. Our aim was to investigate the mechanisms by which obesity affects subcutaneous white adipose tissue (WAT) stem cells. We used microarrays to analyze differences in transcriptomic profiles between the adipose stem cells from morbidly obese and non-obese individuals.

(Submitter supplied) Obesity is a major risk factor for a high number of secondary diseases, including cancer. Specific insights into the role of gender differences and secondary co-morbidities, such as type 2 diabetes (T2D) and cancer risk, are yet to be fully obtained. The aim of this study is thus to find a correlation between the transcriptional deregulation present in the subcutaneous adipose tissue of obese patients and the risk of cancer, in the presence of T2D, and considering gender differences. more...
