Room temperature in continental US; may vary elsewhere. Background
Transforming growth factors (TGF's) are polypeptides that can confer phenotypic transformation to several normal cells. TGF-α binds to the receptor for epidermal growth factor (EGF) and has been isolated from a variety of tumor cells. TGF-α is synthesized in embryos during early fetal development, in several virally transformed cells, and in a large variety of human tumors[1]. TGF-α is a member of the epidermal growth factor family of mitogens and associated with progression of transformed properties in human colon cancer cells[2]. |
