We have demonstrated for the first time that suramin is taken up by human dermal microvascular endothelial (HMEC-1) cells by an active process involving the caveolae system. The uptake of suramin was time-dependent and reduced by more than 90% when incubated in the presence of albumin or at 4 degrees C. Suramin uptake was also inhibited when incubated in the presence of filipin and digitonin, both potent cholesterol-binding agents, but not in the presence of probenecid. The [3H]suramin taken up by the HMEC-1 cells was located primarily within the nucleus, followed by the cytoplasmic fraction. The presence of suramin in these cellular compartments suggests that this drug may act through intracellular mechanisms.
