Open chromatin profiling (ATAC-seq) of SGBS human preadipocytes (days 0, 2, 8 and 16 of differentiation to adipocytes) and iPSC-derived hypothalamic neurons (days 12, 16 and 27 of differentiation)

Project description:Human SGBS preadipocytes were differentiated into adipocytes, and human iPSCs were differentiated into hypothalamic neurons. Cells were collected for ATAC-seq at several differentiation stages. The differentiations were performed in one biological replicate, with two technical replicates (different wells of the differentiation that were also processed individually during library preparation). SGBS Day0: Represents the preadipocyte state. SGBS Day2: Represents immature adipocytes. SGBS Day8: Represents early mature adipocytes. SGBS Day16: Represents mature adipocytes. Hypothalamic Day 12: Represents early hypothalamic neurons. Hypothalamic Day 16: Represents mid hypothalamic neurons. Hypothalamic Day 27: Represents mature hypothalamic neurons.

Gene expression profiling (RNA-seq) of SGBS human preadipocytes (days 0, 2, 8 and 16 of differentiation to adipocytes) and iPSC-derived hypothalamic neurons (days 12, 16 and 27 of differentiation)

Project description:Human SGBS preadipocytes were differentiated into adipocytes, and human iPSCs were differentiated into hypothalamic neurons. Cells were collected for RNA-seq at several differentiation stages. The differentiations were performed in one biological replicate, with three technical replicates (different wells of the differentiation that were also processed individually during library preparation). SGBS Day0: Represents the preadipocyte state. SGBS Day2: Represents immature adipocytes. SGBS Day8: Represents early mature adipocytes. SGBS Day16: Represents mature adipocytes. Hypothalamic Day 12: Represents early hypothalamic neurons. Hypothalamic Day 16: Represents mid hypothalamic neurons. Hypothalamic Day 27: Represents mature hypothalamic neurons.

Effects of plasticizers on adult human adipocytes (SGBS) using global proteomics

Project description:SGBS cells were used as a model system to investigate the cellular mode of action of a variety of plasticizers in human adipocytes. In brief, cells were cultured at 5% CO2 and 37°C in 95% humidity. Cells of generation 40 and passage 3 after thawing were grown to confluence with DMEM/F12 containing 33 µM biotin, 17 µM pantothenate, 100 U/l penicillin, and 0.1 mg/l streptomycin (basal medium) supplemented with 10% FCS (Gibco, Carlsbad, CA, USA). According to the standard differentiation protocol, differentiation was initiated (day 0) after changing to serum-free basal medium supplemented with 0.1 μM cortisol, 0.01 mg/ml apo-transferrin, 0.2 nM triiodothyronine, and 20 nM human insulin (differentiation medium) with the addition of 2 µM rosiglitazone, 25 nM dexamethasone, and 200 µM 3-isobutyl-1-methylxanthine for the first four days. SGBS cells were first differentiated according to the standard protocol for 12 days. Obtained adult adipocytes were then exposed to the plasticizers for 8 days with medium changes every second day. The control contained equivalent amounts of solvent (0.01% MeOH). Additinally, a control on day 12 before exposure was sampled. All SGBS cell culture experiments were conducted in quadruplets.

Expression data from human SGBS adipocytes under hypoxic conditions

Project description:Hypoxia in adipose tissue is suggested to be involved in the development of a chronic mild inflammation, which in obesity can further lead to insulin-resistance. The effect of hypoxia on gene expression in adipocytes seems to play a central role in this inflammatory response observed in obesity. However, the global impact of hypoxia on transcriptional changes in human adipocytes is unclear. Therefore, we compared gene expression profiles of human Simpson-Golabi-Behmel syndrome (SGBS) adipocytes under normoxic or hypoxic conditions to detect hypoxia-responsive genes in adipocytes by using whole human genome microarrays. Human SGBS adipocytes were cultured in a hypoxic environment (1% O2) for 3, 6 and 16 hours and the control group was cultured under normoxic conditions (21% O2). Total RNA was prepared from control and treated SGBS cells, in triplicate experiments, and probes were hybridized on ‘Human Genome U133 2.0’ arrays (Affymetrix).
