Immunohistochemical studies on oncogene products ( EGF R , c erbB 2 ) and growth factors ( EGF , TGF alpha ) in human breast cancer : their relationship to oestrogen receptor status , histological grade , mitotic index and nodal status . ^^^ In this investigation , 83 human mammary carcinomas were examined for the expression of oestrogen receptor ( ER ) , epidermal growth factor receptor ( EGF R ) , epidermal growth factor ( EGF ) , transforming growth factor alpha ( TGF alpha ) , c erbB 2 , histological grade , mitotic index and nodal status , all of which are reportedly prognostically significant factors ( Bloom and Richardson 1957 ; Baak et al . 1985 ; Wright et al . 1989 ) . ^^^ ER expression was biochemically recognized in 43 . 4 % of mammary carcinomas , and EGF R , EGF , TGF alpha and c erbB 2 were histochemically recognized in 25 . 3 , 14 . 5 , 27 . 7 and 18 . 0 % of mammary carcinomas examined respectively , using conventional sections of buffered formalin fixed , paraffin embedded tissue and monoclonal or polyclonal antibodies . ^^^ There were significant relationships between negative ER and positive EGF R or TGF alpha ; positive EGF R and TGF alpha ; positive EGF R and c erbB 2 ; and positive c erbB 2 and TGF alpha . ^^^ Therefore , the present investigation indicates that the negative ER , single expression of c erbB 2 and co expression of EGF R and TGF alpha are important markers which contribute indirectly to prognosis , which reconfirms previous findings on the former two while adding the new finding that immunohistochemical demonstration of expression of EGF R and TGF alpha may provide useful information for selecting the appropriate treatment . . ^^^

We have previously shown that overexpression of a human point mutated c Ha ras proto oncogene , the rat c neu ( c erbB 2 ) proto oncogene , or the human transforming growth factor alpha ( TGF alpha ) gene in MCF 10A cells leads to in vitro transformation of such cells . ^^^ To ascertain whether the introduction of two of these genes into MCF 10A human mammary epithelial cells induces a completely tumorigenic phenotype , we infected MCF 10A Ha ras and MCF 10A TGF alpha cells with a recombinant retroviral vector containing the human c erbB 2 proto oncogene and the hygromycin resistance gene . ^^^ Ten MCF 10A TGF alpha / c erbB 2 ( MCF 10A TE ) and 10 MCF 10A Ha ras / c erbB 2 ( MCF 10A HE ) hygromycin resistant clones were randomly selected and expanded into cell lines . ^^^ Moreover , both MCF 10A TE and MCF 10A HE clones exhibited a fivefold to 20 fold higher cloning efficiency in soft agar than MCF 10A Ha ras , MCF 10A c erbB 2 , or MCF 10A TGF alpha clones . ^^^ These results suggest that c Ha ras , c erbB 2 , and TGF alpha genes have an additive effect on the in vitro transformation of an immortalized human mammary epithelial cell line , but that additional genetic changes such as activation of other proto oncogenes or inactivation of a tumor suppressor gene may be necessary to elicit a fully tumorigenic phenotype . . ^^^

Transgenic mice expressing either the neu proto oncogene or transforming growth factor ( TGF alpha ) in the mammary epithelium develop spontaneous focal mammary tumors that occur after a long latency . ^^^ Since the epidermal growth factor receptor ( EGFR ) and Neu are capable of forming heterodimers that are responsive to EGFR ligands such as TGF alpha , we examined whether coexpression of TGF alpha and Neu in mammary epithelium could cooperate to accelerate the onset of mammary tumors . ^^^ To test this hypothesis , we interbred separate transgenic strains harboring either a mouse mammary tumor virus / TGF alpha or a mouse mammary tumor virus / neu transgene to generate bitransgenic mice that coexpress TGF alpha and neu in the mammary epithelium . ^^^ Female mice coexpressing TGF alpha and neu developed multifocal mammary tumors which arose after a significantly shorter latency period than either parental strain alone . ^^^ Taken together , these observations suggest that Neu and TGF alpha cooperate in mammary tumorigenesis through a mechanism involving Neu and EGFR transactivation . . ^^^
