While the normal human erbB-2 gene is potently transforming when overexpressed in NIH 3T3 cells, its rat homolog, the neu gene, seems to acquire transforming properties only upon alteration of its coding sequence. In this study, we compared the effects of different levels of expression of normal erbB-2 and neu in NIH 3T3 cells. Our results revealed that the normal rat neu gene acts as a potent oncogene when sufficiently overexpressed in NIH 3T3 cells.

The type I growth factor receptor family is increasingly recognized as important in the development and maintenance of breast cancer. The family currently consists of four closely related members: the epidermal growth factor receptor (EGF-R/erbB-1), erbB-2, erbB-3 and erbB-4. Putative ligands which bind directly to or indirectly activate erbB-2/3/4 have been characterized recently. This still growing family of EGF-related growth factors includes gp30, its homolog heregulin (HRG), the rat homolog neu differentiation factor (NDF), glial growth factors (GLIA), ARIA and a 50 kDa factor from COLO 16 cells. The understanding of the function, biology and interactions of these growth factor receptors and their ligands will have far-reaching implications for the prognosis and treatment of breast cancer. This review focuses on advances and future directions for further investigations intended to clarify the mechanism and significance of erbB/ligand interactions in breast cancer.
