Acetylome dynamics during differentiation of SGBS adipocytes

ABSTRACT: Here, we identified temporal dynamics of the acetylome during adipocyte differentiation in human SGBS cells, applying untargeted proteomics in combination with immunoaffinity purification of acetylated peptides. Samples were taken at initiation of differentiation, at an intermediate and terminal time point.

Obesity, characterized by enlarged and dysfunctional adipose tissue, is among today's most pressing global public health challenges with continuously increasing prevalence. Despite the importance of post-translational protein modifications (PTMs) in cellular signaling, knowledge of their impact on adipogenesis remains limited. Here, we studied the temporal dynamics of transcriptome, proteome, central carbon metabolites, and the acetyl- and phosphoproteome during adipogenesis using LC-MS/MS combi ...[more]

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.

The positive control was differentiated using the standard protocol with rosiglitazone. For plasticizer treatments, differentiation was conducted without rosiglitazone and cells were continuously exposed from day 0 – day 16 to the plasticizers or their transformation products. As for plasticizer treatments, the negative control was differentiated with rosiglitazone-free medium containing equivalent amounts of solvent (0.01 MeOH, v/v) for 16 days, resulting in minimal differentiation. All media were renewed every second day to mimic continuous exposure.

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.
