Amphiregulin, epidermal growth factor receptor, and estrogen receptor expression in human primary breast cancer.


Amphiregulin is a recently described member of the epidermal growth factor family. Primary breast cancers were assessed for expression of amphiregulin by immunochemistry (111 cases), Northern, and/or dot blots (68 cases). Epidermal growth factor and estrogen receptors were measured in all cases. p53 and erbB-2 expression was assessed by immunohistochemistry… (More)
