| Title |
H3K27ac hMADS brite rep2, day 19 |
| Sample type |
SRA |
| |
|
| Source name |
human adipose-derived stem cells
|
| Organism |
Homo sapiens |
| Characteristics |
cell line: hMADS-3
cell type: human adipose-derived stem cells
chip antibody: H3K27ac (ab4729; Abcam)
|
| Treatment protocol |
Two days post confluence (day 0) hMADS cells were induced to differentiate in DMEM/Ham`s F12 (Lonza) supplemented with 10 μg/ml transferrin, 1 μM dexamethasone, 500 μM 3-isobutyl-1-methylxanthine (MIX), 0.85 μM insulin, and 0.2 nM T3. At day 3 of differentiation, MIX and dexamethasone were omitted from the media and 0.5 μM rosiglitazone was added until day 9 of differentiation and again from day 13-16 for induction of brite adipocytes. Control white adipocytes were treated with DMSO from day 13-16. From day 16 and forth the differentiation medium of both white and brite adipocytes was depleted of rosiglitazone. White and brite hMADS adipocytes were harvested on day 19, unless stated otherwise.
|
| Growth protocol |
Human multipotent adipose-derived stem (hMADS-3) cells were cultured in DMEM (Lonza, low glucose) supplemented with 10% fetal bovine serum (Lonza), 10 mM Hepes, 2 mM L-glutamine (Lonza), penicillin (62.5 μg/ml), streptomycin (100 μg/ml), and 2.5 ng/ml hFGF2 (Peprotech).

| Extraction protocol |
ChIP experiments were performed in mature hMADS adipocytes essentially as previously described (Siersbæk et al. 2012, MCB, 32: 3452-3463). For cross-linking of chromatin, 0.2 mM disuccinimidyl glutarate (DSG) was applied (Proteochem, Denver, CO) for 45 min followed by cross-linking using 1% formaldehyde for 10 min.
ChIP-seq libraries were constructed according to the manufacturer's instructions (Illumina) as described in (Nielsen R, Mandrup S, 2014 Genome-Wide Profiling of Transcription Factor Binding and Epigenetic Marks in Adipocytes by ChIP-seq. Methods in Enzymology 2014, Vol. 537, pp. 261-279).

Alignment:
Sequence reads were collapsed using FASTX-Toolkit (http://hannonlab.cshl.edu/fastx_toolkit/). Bowtie (Langmead B, et al., Genome Biol. 10:R25) was used to align each collapsed library to the human reference genome (version hg19) with the following parameters: “-m 3 –best –strata”, with all other parameters default.
Peak finding and visualization:
BedGraph files were created using HOMER (Heinz S, et al. 2010. Mol. Cell 38:576 –589) for visualization of binding profiles.
Genome_build: hg19
