Figure 3From: Gene expression profiles derived from fine needle aspiration correlate with response to systemic chemotherapy in breast cancerReal-time quantitative RT-PCR analysis of gene expression confirms the cDNA micoarray data. Expressions of selected genes were examined using RT-PCR in all FNA breast tumors. The expression level of each gene in the tumor samples was compared to the reference MCF10A cell line. All RT-PCR data have been normalized to β-actin. White and black columns represent good and poor responders, respectively.Back to article page
