(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) Normal-weight polycystic ovary syndrome (PCOS) women exhibit adipose tissue dysfunction in vivo accompanied by enhanced subcutaneous (SC) abdominal adipose stem cell (ASC) development to adipocytes with greater lipid accumulation per cell in vitro. The goal of this study was to determine whether this phenomenon is associated with abnormal adipogenic gene transcription using RNA-sequencing to examine differential transcription patterns in PCOS vs controls. more...

(Submitter supplied) In vitro studies of subcutaneous (SC) abdominal adipose stem cells (ASC) from women with polycystic ovary syndrome (PCOS) show altered ASC commitment to preadipocytes and differentiation to mature adipocytes related to hyperandrogenism. The goal of the study is to use microarrays to examine whether SC abdominal ASC gene expression are altered in normal-weight PCOS women and correlated with hyperandrogenemia and/or insulin resistance, which are prevalent clinical pathologies of PCOS.

(Submitter supplied) Polycystic ovary syndrome (PCOS) is a female endocrine disorder characterized by hyperandrogenism, chronic anovulation, and polycystic ovaries. PCOS is often accompanied by symptoms such as insulin resistance, abdominal obesity, and chronic inflammation. Adipose tissue is a crucial endocrine organ involved in metabolic disorders. Metabolic issues and chronic inflammation in PCOS are linked to dysfunctional adipose tissue. more...

(Submitter supplied) The gene encoding for transcription factor 7-like 2 (TCF7L2) is the strongest type 2 diabetes (T2DM) candidate gene discovered to date. While its association with T2DM has been replicated in most populations worldwide, the molecular and physiological mechanisms that underlie this association remain largely unknown. As a key transcriptional effector of the Wnt/β-catenin signaling pathway, we hypothesized that TCF7L2 plays an important role in the development and function of adipocytes. 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) Here we demonstrate that the loss of GPS2 triggers the reprogramming of cellular processes related to adipocyte differentiation by increasing the responses to the adipogenic cocktail. Moreover, GPS2-depleted human adipocytes are characterized by hypertrophy, triglyceride and phospholipid accumulation, and sphingomyelin depletion. These changes are likely a consequence of the increased expression of ATP-Binding cassette subfamily G member 1 (ABCG1) that mediates sphingomyelin efflux from adipocytes and modulates lipoprotein lipase (LPL) activity. more...

(Submitter supplied) This study seeks to undertake an assessment of the effects of prenatal exposure of female sheep to excess testosterone, the estrogen precursor, in four different adipose depots. The depots investigated are subcutaneous adipose tissue (SAT) - a fat beneath the skin storing >80% of total body fat in the human body, visceral adipose tissue (VAT) - an intra-abdominal fat primarily associated with digestive system organs, and smaller depots such as epicardial adipose tissue (ECAT) and perirenal adipose tissue (PRAT) that serve specialized functions associated with the organs/tissues in their proximity. more...

(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) RNAseq was performed in siJARID2 and control siRNA-treated human adipose tissue derived stem cells (hASC). The tretment of siRNA was performed by electroporation one day before induction of differentiation in vitro. The cells were lyzed and RNA was purified on day 6 (mid differentiation) and day 13 (full differentiation) from differentiation start.

(Submitter supplied) GWAS studies and our own work have identified RSPO3 as a gene modulating human body fat distribution. The GWAS signal at RSPO3 is coincident with an eQTL in mature adipocytes. To assess the effects of RSPO3 on abdominal and gluteal adipocyte biology, we undertook inducible RSPO3-knockdown in in vitro differentiated immortalized human abdominal and gluteal adipocyte cell lines (DFAT cells).

While the transcriptomic and epigenomic changes during adipogenesis and osteogenesis have been characterized, what happens to the chromatin loops is hardly known. Here we induced hMSCs to adipogenic and osteogenic differentiation, and performed 2 kb resolution Hi-C experiments for loop detection and generated RNA-seq, histone modification ChIP-seq and ATAC-seq data for integrative analysis before and after differentiation. more...

(Submitter supplied) TWIST2 is a transcription factor heavily involved in proper development. We queried the role of TWIST2 in 3T3-L1 adipogenesis by silencing gene expression using a lentiviral-delivered shRNA and performed RNA-seq at various time points following initiation of differentiation. We found that previously identified TWIST2-target genes increase in transcription, suggesting that TWIST2 acts as a transcriptional repressor in this system.
