Pazopanib synergizes with docetaxel in the treatment of bladder cancer cells.

ABSTRACT:

Objectives

To investigate the efficacy of pazopanib, both alone and in combination with docetaxel, in bladder cancer cells. Bladder cancer expresses many potential therapeutic targets of biological agents, including the vascular endothelial growth factor receptor (VEGFR). Pazopanib is a small molecule inhibitor of VEGFR-1, -2-3, platelet-derived growth factor receptor (PDGFR), and c-Kit.

Materials and methods

Using human bladder cancer cells HTB3, HT1376, J82, RT4, CRL1749, T24, Sup, and HTB9, the treatment effect of pazopanib and cytotoxic chemotherapy was assessed using a tetrazolium-based assay. The combinatorial effect of these agents on clonogenic growth was further examined. Western blotting was used to assess changes in relevant downstream targets, including phospho-A
