Q-PCR validation of the expression of the 41 selected genes in cell lines.

Q-PCR analysis was done according to the Material&Methods on the same samples set used in microarray analysis. Gene symbol and TaqMan assay (assay ID) are indicated. The genes that were found differentially expressed (L235) or not significantly modulated using microarray are displayed in bold and italics, respectively, and classified as fully validated genes or potential false discoveries considering the Q-PCR results. The Ct values correspond to the median of threshold cycles of [PIP+] and [PIP−] samples. The expression changes (ratio) between the [PIP+] and the [PIP−] samples are specified as negative (down-regulated) or positive (up-regulated) values. Adjusted p-values were computed using z statistics with false discovery rate corrections (α = 0.05).
