The aim of the study was to determine how statin drugs affect endothelial cell shape and F-actin cytoskeleton arrangement. (Endothelial cells are the thin layer of cells that line the interior surface of blood vessels and lymphatic vessels, and F-actin cytoskeleton is part of the cells scaffolding or skeleton). In the study, human endothelial cells were cultured in the laboratory and were then treated with statins.
The study found:
(a) After been treated with statins the endothelial cells became rounded, which is associated with unhealthy cells in arteries prone to developing a build up of plaque.
(b) After been treated with statins the F-actin cytoskeleton structure was disorganized and fragmented which can lead to cell death.
The significance of the results of the study is that endothelial cells and F-actin cytoskeleton arrangement are advesely impacted by statin treatment which may increase the risk of arterial plaque and cell death.
