Purpose: To study the role of prolactin (PRL) and its antagonist, G129R, in HER2/Neu tumorigenesis. Specifically, to investigate the interaction between the oncogene HER2 and the PRL receptor (PRLR) signaling pathways for designing effective combinational therapeutics for breast cancer.
Experimental Design: The combination effects of G129R and an anti-HER2 antibody, Herceptin, were tested against HER2-overexpressing human breast cancer cell lines, T-47D and BT-474, using cell based assays and xenografts established in athymic mice. Furthermore, four different bitransgenic mouse lines co-expressing the murine version of HER2 and PRL or G129R were generated. The mammary tumor incidence, characterization of mammary gland development, …
