Figure 7From: Epidermal Growth Factor Receptor (EGFR) mutation analysis, gene expression profiling and EGFR protein expression in primary prostate cancer Differentially expressed genes identified by microarray analysis were validated by relative qRT-PCR. White bars represent the average mRNA levels of each gene in EGFRlow class; gray bars represent the average mRNA levels of each gene in EGFRhigh class. Fold-change was calculated as described in "methods" section.Back to article page
