Figure 2. Pazopanib and vorinostat interact to kill multiple sarcoma cell lines. Sarcoma cells were treated with vehicle (VEH, DMSO), pazopanib (PAZ, 5.0 μM) and/or vorinostat (500 nM) as indicated. Cells were isolated 48h after exposure and viability determined by trypan blue exclusion (n = 3, ± SEM) *P < greater than vehicle control.
