Among the processes contributing to the progressive acquisition of the highly malignant phenotype in breast cancer are ovarian-independent growth, antioestrogen resistance and increased metastatic potential. We have previously observed that increased invasiveness and development of ovarian-independent growth occur independently. In an attempt to define the(More)
It has been suggested that transforming growth factor-alpha (TGF-alpha) is a mitogenic autocrine growth factor for human breast cancer cells, responsible for mediating the mitogenic effects of 17 beta-estradiol (E2) in responsive cells. To test this hypothesis we have introduced eukaryotic expression vectors directing the expression of TGF-alpha mRNA into(More)
