|
|
Source name |
pancreas
|
Organism |
Mus musculus |
Characteristics |
tissue: pancreas genotype: Ptf1a(CreER/fl)
|
Treatment protocol |
Tamoxifen treatment: On day 0, 1, 2, mice received 0.25 mg tamoxifen/g mouse at 50 mg/ml in corn oil by gavage. Mice were sacrificed on day 6.

Extracted molecule |
total RNA |
Extraction protocol |
RNA preparation: pancreas was homogenized in 4 M Guanidine Thiocyanate, 0.1 M Tris HCl pH 7.5, 1% 2-mercaptoethanol with a Tekmar Tissuemizer. RNA was isolated from an aliquot of the homogenate by addition of N-Lauroylsarcosine sodium salt to 0.5%, Potassium Acetate pH 5.5 to 0.1 M, and Acetic Acid to 0.08 M, followed by addition of 0.75 volume ethanol while vortexing. RNA was allowed to precipitate from the solution at -20 C for at least 1 hour, collected by centrifugation at 12,000 g for 5', and the RNA pellet resuspended in Trizol (equal volume to starting homogenate). Subsequent steps were as per manufacturer's protocol (Life Technologies). RNA libraries were prepared for sequencing using standard Illumina True-seq protocols

Data processing |
Illumina HiSeq Control Software version 2.0.10.0 used for basecalling Sequences were mapped to mm9 mouse genome using TopHat v2.0.4 (by use of Bowtie v0.12.7.0) with parameters --no-novel-juncs --segment -length 25 --segment-mismatches 3 Sequences per gene were counted using Samtools ( v0.1.18.0) /HTSeq (v0.6.0) Counts-per-million (CPM) were calculated using TMM normalization according to Robinson et al., Bioinformatics, 2010. Data set was filtered for minimal expression by "keep <- rowSums(cpm(d)) >= 3" Differential gene expression analysis was performed with edgeR v3.0.8 (FDR < 0.05) Genome_build: mm9 Supplementary_files_format_and_content: Normalized counts-per-million (CPM) for each sample in tab-delimited text file Supplementary_files_format_and_content: EdgeR results as .xlxs spreadsheets, all results as DE_Ptf1a_cKO 6-day, and fdr < 0.05.
