Abstract

Previous studies have shown the anti-inflammatory and antioxidant properties of phenolic compounds of virgin olive oil (VOO). However, the effect of bioavailable phenolic compounds on the vascular endothelium is unknown. We aimed to evaluate the effect of the consumption of virgin olive oil rich in phenolic compounds on the vascular endothelium. We treated HUVEC with human serum obtained in fasting state and after the intake of a breakfast prepared with VOO with a high or low content of phenolic compounds. Treatment of HUVEC with serum obtained 2 h after the intake of the high-phenol VOO-based breakfast decreased p65 and MCP-1 gene expression (p < 0.001 and p = 0.002, respectively) and increased MT-CYB, SDHA and SOD1 gene expression (p = 0.004, p = 0.012 and p = 0.001, respectively), as compared with the treatment of HUVEC with the serum obtained 2 h after the intake of the low-phenol VOO-based breakfast. The treatment with serum obtained 4 h after the intake of the high-phenol VOO-based breakfast decreased MCP-1 and CAT gene expression (p < 0.001 and p = 0.003, respectively) and increased MT-CYB gene expression (p < 0.001), as compared to the treatment with serum obtained 4 h after the intake of the low-phenol VOO-based breakf...Continue Reading

Anti-inflammatory Treatments

A drug or substance that reduces inflammation (redness, swelling, and pain) in the body. Anti-inflammatory agents block certain substances in the body that cause inflammation and swelling. Discover the latest research on anti-inflammatory treatments here

Atherosclerosis Disease Progression

Atherosclerosis is the buildup of plaque on artery walls, causing stenosis which can eventually lead to clinically apparent cardiovascular disease. Find the latest research on atherosclerosis disease progression here.
