| Title |
CDX2 ISC ChIP-Seq |
| Sample type |
SRA |
| |
|
| Source name |
Control mouse intestinal stem cells
|
| Organism |
Mus musculus |
| Characteristics |
strain: B6;129 mixed background
cell type: Adult intestinal stem cell; proximal 2/3 of intestine
genotype: Cdx2+/+; Lgr5-EGFP-IRES-CREERT2
|
| Treatment protocol |
Not injected with tamoxifen.
|
| Growth protocol |
Crypts from the proximal 2/3 of mouse small intestines were isolated by scraping off villi and incubating in 5mM EDTA in PBS for 45 minutes at 4°C. Crypts were disaggregated with 4X TrypLE in DMEM for 45 minutes at 37°C and Lgr5-GFP-HI intestinal stem cells were sorted by flow cytometry. Cells were snap-frozen in liquid nitrogen and pooled for subsequent ChIP analysis.
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Whole cell lysates were sonicated and incubated with 3 ug CDX2 antibody overnight (Bethyl Labs; A300-691A) for immunoprecipitation.
The ThruPLEX-FD Prep Kit (Rubicon Genomics) was used to prepare libraries, and 50 bp single-end reads were sequenced on an Illumina Hi-Seq 2000 instrument.

| Description |
CDX2_ISC_ChIP-seq
|
| Data processing |
Alignment: ChIP-seq:bowtie. RNA-seq: Tophat, version 2.0.9
ChIP-Seq - peak calling: MACS, version 1.4.2, considering input and local background, p<0.0001 cutoff.
RNA-Seq - normalized and differential expression: Cufflinks, version 2.1.1; settings: -b, -u, and default; Cuffmerge was used with custom 3' 1000 bp reference gtf and default settings; Cuffnorm was used with default settings; Cuffdiff was used with -b, -u and default settings.
Genome_build: mm9
Supplementary_files_format_and_content: ChIP-Seq: Bed file for significant peaks, bigwig file for visualizing aligned sequence tags
Supplementary_files_format_and_content: RNA-Seq: There are two processed data matrices that apply to all the samples. First, is the normalized expression table, prepared using Cuffnorm, which contains the normalized Log2(FPKM+1) expression values for all 9 RNA-seq samples. The second is the differential expression table, prepared using Cuffdiff with an FDR of 5%, which contains average FPKM values for villus, control ISC and Cdx2-del ISC, as well as fold change in expression, P-values, and Q-values corrected for multiple hypothesis testing. The third is the custom gtf used in cuffdiff for correction of 3' bias in the RNA-seq samples.
