Genome-wide analysis of gene expression in murine breast fibroblasts from normal tissue, hyperplasia, adenoma and carcinoma (MMTV-PyMT model)

GSE45256 Mus musculus (mouse) Expression microarray 16 samples Submitted 2013/03/19 Platform GPL6885
At a glance

Expression microarray · mouse · 16 samples

What it is
Expression microarrayGene activity read on a chip (the older technology that RNA-seq replaced).
Organism
Mus musculus (mouse)
Samples
16 samples: 8 conditions, mostly in duplicateGroups are read from the sample names, not from the paper. Check the list below.
Data you can get
A processed expression table (series matrix) and the array files, from NCBI.
Summary (written by the submitters)
Analysis of differences at gene expression level of hpvE6 immortalized fibroblasts isolated from normal mammary glands and from hyperplasia, adenoma and carcinoma stages using the MMTV-PyMT model (FVB/N background). Analysis demonstrated the activation of specific transcriptional programs in fibroblasts from later stages.

Download · which file do I need?

Direct links to NCBI, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need.

All supplementary files ↗
3 · The original raw files

Whole study · RAW.tar

Everything the authors deposited as one archive (GSE45256_RAW.tar), including the raw array or instrument files. Can be large; the picker in step 2 takes just the samples you need.

What the files usually look like: For arrays the series matrix is normally the normalised expression table you want; the raw array files (CEL and similar) are in the RAW.tar.

Also filed as BioProject PRJNA193324. Searching any of these in the dataset finder brings you back here.

Study design
8 conditions, mostly in duplicate
NF2_ongel ×2 NF3_ongel ×2 HpAF1_ongel ×2 AdAF1_ongel ×2 CAF1_ongel ×2 CAF2_ongel ×2 CAF3_ongel ×2 CAF4_ongel ×2

Supports a between-group comparison across 16 samples.

How we read this: 8 replicated groups read from 16 sample titles; they account for 16 of them. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
