IV. Measurement and data processing

A. Data Extraction
Image scanning and software

Procedures and parameters
Hybridized arrays were scanned with ScanArray 4000 (Packard Biochip technologies, Inc. USA) at laser intensity and photomultiplier tube voltage setting giving the best dynamic range for each chip in the two channel, the ratio of the mean signal intensities was ~1, and the percentage of spots with saturated pixels was <0.25% but >0%. Image segmentation and spot local background quantification was performed with analysis software GenePickPro 3.0 (Axon Instruments, Inc. USA).
