Anti-tumor effect of aquaporin 3 monoclonal antibody on syngeneic mouse tumor model.

Aquaporin-3 (AQP3), a water channel protein, has been found to be involved in cancer progression via water and small molecule transport function. However, drug development targeting AQP3 has not yet begun. Here, we showed that a recently established anti-AQP3 monoclonal antibody (mAb) suppresses tumor growth in allograft mouse colorectal tumor models produced using CT26 or MC38 cancer cells.
