Metastases of breast cancer (U133A)

GSE14018 Homo sapiens (human) Expression microarray 36 samples Submitted 2009/05/01 Platform GPL96
At a glance

Expression microarray · human · 36 samples

What it is
Expression microarrayGene activity read on a chip (the older technology that RNA-seq replaced).
Organism
Homo sapiens (human)
Samples
36 samples: 16 × Lung metastasis vs 8 × Bone metastasis vs 7 × Brain metastasis vs 5 × Liver metastasisGroups 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)
Comparisons among breast cancer metastases at different organs revealed distinct microenvironments as characterized by cytokine content. Such microenvironment distinction might be important to dictate how the cancer cells adapt to survival before they successfully colonize. Keywords: Disease state analyses

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 (GSE14018_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 PRJNA114535. Searching any of these in the dataset finder brings you back here.

Study design
16 × Lung metastasis vs 8 × Bone metastasis vs 7 × Brain metastasis vs 5 × Liver metastasis

Supports a between-group comparison across 36 samples.

How we read this: 4 replicated groups read from 36 sample titles; they account for 36 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.
