The expression of VEGF and VEGFR1 in cultured ER-positive (MCF-7) and ERnegative (MDA-MB-231) human breast cancer cells. ELISA assay showed that VEGF protein was expressed much more in ER-negative (MDA-MB-231) human breast cancer cells than in ER-positive (MCF-7) human breast cancer cells (>8-fold; p < 0.01; n = 8). Also, VEGF receptor-1 (flt-1) protein was more highly expressed in ER-negative (MDA-MB-231) human breast cancer cells than ER-positive (MCF-7) human breast cancer cells (>7-fold; p < 0.01; n = 8).
