To this end, we performed PPARg ChIP-seq in both tissues and called each tissue-spsecific binding sites.

BAT and eWAT samples were cross-linked with 1% formaldehyde, and used for ChIP with PPARg antibody. Nuclei were lysed and sonicated. Protein-DNA complexes were isolated from lysates using antibodies, and DNA were extracted. For each condition, ChIP was performed on lysates from 4 different mice, and ChIPed DNA or input DNA samples were pooled for sequencing. ChIPed DNA or input DNA samples were pooled for sequencing. 8-10 week old male Sv129 mice has been housed in regular 12h light/12h dark cycles on normal chow diet. Sequencing: High throughput sequencing was done by the Functional Genomics Core of the Penn Diabetes Research Center using the Illumina Genome Analyzer IIx or HiSeq 2000, and the reads were aligned to the mm8 genome assembly genome using Bowtie. In each ChIP-seq sample, all the duplicate reads were removed except for one before downstream analysis. Peak Calling: To identify depot-specific Pparg peaks, we performed peak calling for one depot sample as foreground and the other sample as background, and vice versa. All the peak calling were performed using Homer with options, peak size 200bp and minimum distance 200bp (-size 200 -minDist 200), then 1 rpm cutoff was applied. Common Pparg peaks were defined as follows. First, Pparg peaks were called for each depot using a matching input sample, then all the peaks were pooled and overlapping peaks were merged. Among these peaks, any peak that overlaps with the depot-specific Pparg peaks were eliminated, and the remaining peaks were defined as common Pparg peaks. It should be noted that our definition of common peak here is naïve in the sense that some peaks might show different peak height between different depots. However, this should not be a problem in this work because our primary target is to identify depot-specific (especially BAT-specific) Pparg binding sites.
