Summary
This data set was generated to study the effects of strain and stress on hippocampal gene expression in female mice. The data set includes three inbred strains of mice and four treatment groups.
Experiment design
This data set includes four experimental conditions, B (baseline, untreated), C (chronic mild stress), CR (chronic mild stress followed by acute restraint), and R (acute restraint only).
B = untreated
C = 7 weeks of chronic unpredictable stress
R = 30 minutes of restraint
CR = 7 weeks of chronic unpredictable stress followed by 30 minutes of restraint
About cases
The original data set included four individuals of each strain under baseline (B) conditions and eight individuals from each strain for each of the treatment groups, chronic mild stress (C), acute restraint (R), and chronic mild stress followed by acute retraint (CR). However, some samples have been removed due to technical problems with tissue collection or microarray performance.

This data set includes expression data from mouse hippocampus.
About data processing
Outlier Detection. Samples 7 (J-CR-21), 24 (N-R-29), and 40 (D-R-6) were detected as outliers and have abnormal expression profiles (i.e. they do not cluster with other samples and have abnormal median and quartile ranges after normalization. These samples have been removed from the analysis.
RMA Algorithm. The Robust Multichip Analysis (RMA) algorithm fits a robust linear model at the probe level to minimize the effect of probe-specific affinity differences. This approach: n Increases sensitivity to small changes between experiment and control samples. n Minimizes variance across the dynamic range, but does compress calculated fold change values. RMA consists of three steps: 1. Background adjustment 2. Quantile normalization 3. Summarization This is a multi-chip analysis approach. Therefore, all arrays intended for comparison should be included together in the summarization step. For a more detailed description of the RMA algorithm, see the publication, Exploration, Normalization, and Summaries of High Density Oligonucleotide Array Probe Level Data, Biostatistics, April 2003; Vol. 4; Number 2: 249–264.
