Effects of FVP treatment on genes modulated by dnCDK9 in hTERT-immortalized normal human fibroblasts. Affymetrix microarray expression ratios for transcripts changing +/-1 log2 with ectopic expression of dnCDK9 were clustered with the corresponding values of the FVP treatments using hierarchical clustering analysis (correlation uncentered, average linkage). Correlations among treatments are shown on the top dendogram. Gene clusters are shown on the left of the heat map. A heat map legend is shown.
