Expression of Signal Molecules in Culture of Human Endothelial Cells in Atherosclerosis and Restenosis.

We compared the expression of signal molecules in the culture of human endothelial cells under normal conditions and in atherosclerosis and restenosis. Expression of connexin-37 and sirtuin-1 in atherosclerosis and restenosis surpassed the normal by 2 and 5 times, respectively, and expression of endothelin-1 3-fold surpassed the normal. In restenosis, changes in the expression connexin-37 and endothelin-1 became more pronounced in comparison with atherosclerosis. Connexin-37 and endothelin-1 can serve as predictive markers for prognosis of post-stenting complications in patients with atherosclerosis.
