  • 1° samples, cDNA made using the same RNA that was used to produce cRNA for microarray hybridization.

    2° samples, independently extracted, triplicate RNA samples used to make cDNA.

    RT-PCR, quantitative real-time reverse-transcription PCR.

  • * Number of nine pairwise comparisons showing a significant increase or decrease (P<0.0025) by Wilcoxon's Signed Rank Test.
