Anti-HER3 domain 1 and 3 antibodies reduce tumor growth by hindering HER2/HER3 dimerization and AKT-induced MDM2, XIAP, and FoxO1 phosphorylation.

Blockade of the human epidermal growth factor receptor 3 (HER3) and of the downstream phosphatidylinositide 3-kinase (PI3K)/AKT pathway is a prerequisite for overcoming drug resistance and to develop novel treatments for cancers that are not eligible for the currently approved targeted therapies. To this end, we generated specific antibodies (Abs) against… CONTINUE READING
