Supplemental Figure Legends Fig. S1. Effects of high fat diet on body weight, liver triglyceride level, and expression of hepatic lipogenic genes. (A) Summary of animal profiles used for ChIP-seq analysis. Mice were fed normal or high fat chow for 20 weeks and body weight s were monitored. Statistical significance was determined by the Student’s t-test (SEM, n=3, 4). (*,p<0.01). Mice were fed normal or high fat chow for 20 weeks and oil-red staining of liver sections was performed (B) and mRNA levels of genes involved in hepatic lipogenesis were measured by q-RTPCR (C). Statistical significance was determined by the Student’s t-test (SEM, n=3). (*,p<0.05). Fig. S2. Effects of high fat diet on expression of endogenous FXR. Mice were fed normal or high fat chow for 16 weeks and livers were collected for measuring protein (A, B) and mRNA levels (C) of FXR. Statistical significance was determined by the Student’s t-test (SEM, n=3 for normal mice, n=4 for dietary obese mice). (*,p<0.01, NS, statistically not significant). Fig. S3. Supplemental information for detailed experimental procedures. ChIP assays: Liver tissue from mice was collected, and proteins and DNA were cross-linked with 1% formaldehyde in PBS at room temperature for 10 min. Cross-linking was stopped by adding 125 mM glycine followed by washing the tissue twice with ice-cold PBS. The tissues were resuspended in hypotonic buffer (10 mM HEPES, pH 7.9, 1.5 mM MgCl2, 10 mM KCl, 0.2% NP40, 0.15 mM spermine, 0.5 mM spermidine, 1 mM EDTA, 5% sucrose) and cells were broken by Dounce homogenization and nuclei were isolated by centrifugation. The nuclei were resuspended in sonication buffer (50 mM Tris-HCl, pH 8.0, 2 mM EDTA, 1% SDS) and sonicated to reduce the DNA length to 200-800 bp. After centrifugation, the supernatant was diluted, pre-cleared by incubation with a 25% protein G-Sepharose slurry at 4oC for 30 min, and chromatin was immunoprecipitated with 1-2 microgram of antibodies to FXR (Santa Cruz, H130 and C20) or IgG as a negative control, at 4oC overnight. The immune complexes were collected by incubation with 50 microliter of a 25% protein G Sepharose slurry for 1 h and the beads were washed extensively with low salt, high salt, and LiCl wash buffers followed by washing twice with Tris-EDTA (TE) buffer. After the elution of bound chromatin, the genomic DNA was purified by phenol-chloroform extraction and subjected to PCR or qPCR using primers specific for the Shp and Ost beta promoter region which are known to contain a FXR binding region or the Gapdh promoter as a negative control. Deep sequencing of ChIP-DNAs and genomic mapping of DNA reads: Twenty ng of DNA from chromatin that had been immunoprecipitated by FXR antibody, or IgG (negative control) in samples from normal or obese mice were used for ChIP-seq library construction (Illumina). Deep sequencing was then done using the Illumina/Solexa Genome Analyzer II (Biotechonology Center, UIUC). Fully sequenced ChIP-DNA (50 bp) was used for genome alignment with Mus musculus genome sequences, NCBI m37 genome assembly (mm9: July 2007) as a reference sequence, allowing 2 bp mismatches. Sequences aligned to the mouse genome sequence were subjected to analysis with CisGenome (v1.2) to generate FXR binding site peaks using a false discovery rate (FDR) cutoff ( <0.001). For the FXR peak identification in the GW4064-treated samples, two criteria such as FDR (<0.001) and ratio (>5) of FXR binding to IgG peaks were used in both diet groups to detect binding sites. Gene Annotation and Gene Ontology (GO) analysis: FXR binding sites (15,263 and 5,272) in normal or high fat diet samples were analyzed to identify the gene locations of the sites in the mouse genome. A list of all genes with FXR peaks within ± 10 kb of the genes was generated using CisGenome. Annotated genes near FXR binding sites uniquely detected in either the normal or high fat groups were 2,583 or 1,566, respectively. GO analysis of FXR target genes was conducted by using the NIH database for Annotation, Visualization, and Integrated Discovery (DAVID: http://david.acc.ncifcrf.gov/) for functional grouping of binding genes. This analysis was also used to classify the genes into functionally related groups by using PANTHER biological process terms (http://www.pantherdb.org). All sequence analyses were conducted based on the Mus musculus NCBI m37 genome assembly (mm9:July 2007) accessed from Ensemble. Enrichment scores and P-values were also generated by this analysis. Motif search: The enrichment of motifs within the 250 top scoring FXR binding peaks, with exception of simple repeats in the ChIP-seq data of ND or HFD fed groups was analyzed in MEME (Multiple Em for Motif Elicitation; http://www.meme.sdsc.edu) as position dependent letter-probability matrices. The coordinates of each peak are set to collect motif lengths of 6 to 20 bp. Comparison of motifs against a database of known FXRE’s was done in TOMTOM generating p-values of the similarity score, scoring details and a logo alignment for each match. Fig. S4. List of mouse gene primer sequences for ChIP (A) and q-RTPCR (B) analyses. Fig.S5. GW4064 treatment resulted in increased FXR binding at known target genes. Normal or high fat dietary obese mice were injected i.p with vehicle or GW4064 and after 1 h livers were collected. (A) Relative occupancies of FXR at the Shp and Ostgene were determined by ChIP assays using FXR antibody and control IgG. FXR binding in vehicle-treated normal mice was set to 1. (B) The mRNA levels of the Shp gene were determined by q-RTPCR. Three independent ChIP assays were done in mouse liver and genomic DNA was pooled and analyzed by genomic sequencing. Fig.S6.

Effects of GW4064 on FXR binding sites unique to either normal or obese mice by ChIP-seq. ChIP-seq data showing FXR binding sites in vehicle- or GW4064-treated normal and obese mice are displayed using the UCSC genome browser. Chromosomal locations are shown at the top of each display. The Y-axis shows the number of mapped sequence tags. Gene positions are indicated at the bottom of each display with the arrows indicating the transcriptional start site. Fig. S12. Effects of GW4064 treatment on mRNA levels of potential FXR target genes. Normal mice were treated with vehicle or GW4064 for a short time, 1 h, to examine direct effects of GW4064 on expression of potential FXR target genes. The mRNA levels of genes nearest to FXR binding sites that were unique to normal mice were determined by q-RTPCR. Statistical significance was determined by the Student’s t test from 11q-RTPCR readings from 4 mice (SEM, n=11).
