Fig. 6. CTGF expression levels are correlated with S100A4 expression levels in samples of primary human breast cancer. (A) RT-PCR analysis of CTGF and S100A4 expression in nine representative samples of 24 analyzed primary breast cancer samples. N, non-tumor counterparts; T, tumor tissue. (B) Graph depicts the significant correlation between CTGF and S100A4 transcript levels determined in all 24 breast cancer samples by densitometric analysis and normalized to GAPDH control (r2=0.65, P=0.0012).
