Transforming growth factor alpha in human mammary carcinomas and their metastases.
A binding competition assay was used to measure the content of transforming growth factor alpha in human mammary carcinomas and their metastases. Thirty one percent of the primary and 50 percent of the metastases expressed the transforming growth factor alpha with values ranging between 1.6 to 278 EGF equivalent ng/mg tumour extract protein. There was no correlation between the transforming growth factor alpha content and the estrogen receptor value.
