Thrombospondin-1 is a matricellular protein involved in the vascular injury response. Statins are cholesterol lowering drugs that have beneficial cardiovascular effects. Statis have been shown to inhibit smooth muscle migration through the mevalonate pathway. This effect is thought to be mediated by small G protein Ras and Rho turnover which requires many hours. While many patients undergoing treatment for vascular disease are on statins, many are not. Thus immediate pretreatment with statins before surgery may be beneficial. We hypothesized that statins have effects independent of the mevalonate pathway and thus have an immediate effect.</p><p><strong>Methods: </strong>Human vascular smooth muscle cells were pretreated for 20 h (long-term) or 20 min (short-term) with fluvastatin, or mevalonolactone plus fluvastatin.
