Effects of 17β-estradiol on the expression of VEGF protein in cultured ER-positive (MCF-7) and ER-negative (MDA-MB-231) human breast cancer cells. ELISA assay showed that 17 β-estradiol (5 nmol/L) significantly increased VEGF expression in cultured ER-positive (MCF-7) human breast cancer cells (1,762 ± 56 vs. 1,136 ± 58 pg/mg; p < 0.01; n = 8) compared to the control group, but not in ER-negative (MDA-MB-231) human breast cancer cells.
