Figure 7From: Epidermal growth factor receptor signalling in human breast cancer cells operates parallel to estrogen receptor α signalling and results in tamoxifen insensitive proliferation Overlap of E2 and EGF regulated genes . Overlap of genes significantly up- (A) or down-regulated (B) (>1.5×) in MCF7-EGFR cells 6 hr after treatment with E2 (10 nM), EGF (100 ng/ml) or E2 + EGF as determined microarray gene expression analysis.Back to article page
