Biphasic effect of FVP in the expression of certain PRG/IRGs. (A) BJ-TERT fibroblasts were treated with 300 nM FVP as described in Figure 1A and the expression of indicated mRNAs was determined by Q-RT-PCR analysis. Data was represented as a fold change value with respect to mRNA expression at time zero. (B) Q-RT-PCR data was converted to log2 ratios and visualized with the same color scale used in microarray analysis using Java-TreeView. (C) Comparison of the log2 ratios obtained from microarray and Q-RT-PCR data at the same time points.
