Abstract
Gain of function of membrane receptor was a good strategy exploited by cancer cells to benefit own growth and survival. Overexpression of HER2 has been found to serve as a target for developing trastuzumab to treat 20-25% of breast cancer. However, little or none of the other membrane receptor was found to be useful as a potential target for breast cancer treatment since then. Here, we showed that amplified signaling of interleukin-17 receptor B (IL-17RB) and its ligand IL-17B promoted tumorigenicity in breast cancer cells and impeded acinus formation in immortalized normal mammary epithelial cells. External signal transmitted through IL-17RB activated nuclear factor-κB to upregulate antiapoptotic factor Bcl-2 and induced etoposide resistance. Elevated expression of IL-17RB had a stronger correlation with poor prognosis than HER2 in breast cancer patients. Interestingly, breast cancer patients with high expression of IL-17RB and HER2 had the shortest survival rate. Depletion of IL-17RB in trastuzumab-resistant breast cancer cells significantly reduced their tumorigenic activity, suggesting that IL-17RB and HER2 have an independent role in breast carcinogenesis. Furthermore, treatment with antibodies specifically against IL-17RB or IL-17B effectively attenuated tumorigenicity of breast cancer cells. These results suggest that the amplified IL-17RB/IL-17B signaling pathways may serve as a therapeutic target for developing treatment to manage IL-17RB-Associated breast cancer.. ? 2014 Macmillan Publishers Limited All rights reserved 0950-9232/14.
