Abstract

Experimental and epidemiological studies have demonstrated the beneficial effects of the traditional Mediterranean diet (TMD) on the incidence and progression of atherosclerosis. Several genes play a major role in determining atherosclerosis susceptibility. We compared the short-term effects of two TMD diets versus a control diet on the expression of pro-atherogenic genes. One TMD diet was supplemented with virgin olive oil (VOO) (TMD+VOO) and the other with nuts (TMD+nuts). Gene expression was analyzed in monocytes from 49 asymptomatic high cardiovascular-risk participants (23 men, 26 women), aged 55-80 years. Monocytes were isolated from blood before and 3 months after dietary intervention. We analyzed the expression of genes involved in inflammation [cyclooxygenase-1 (COX-1), cyclooxygenase-2 (COX-2) and monocyte chemoattractant protein (MCP-1)], genes involved in foam cell formation [low-density lipoprotein receptor-related protein (LRP1), LDL receptor and CD36], and genes involved in thrombosis [tissue factor (TF) and tissue factor pathway inhibitor (TFPI)]. We found that TMD+VOO intervention prevented an increase in COX-2 and LRP1, and reduced MCP-1 expression compared to TMD+nuts or control diet interventions. TMD+nuts specifically increased the expression of CD36 and TFPI compared to TMD+VOO and control diet intervention. Our findings showed that the Mediterranean diet influences expression of key genes involved in vascular inflammation, foam cell formation and thrombosis. Dietary intervention can thus actively modulate the expression of pro-atherothrombotic genes even in a high-risk population.

  • In an intervention study on a population with high risk of ASCVD (n=49), subjects who followed the Mediterranean diet with virgin olive oil or nuts showed a reduction in interleukin-6 and soluble intercellular adhesion molecule-1, and a reduction in activation of biomarkers related to the atherosclerotic process.

    “In an intervention study conducted by Llorente-Cortés et al. in 2010 on a population with a high risk of ASCVD (n = 49), it was found that after 3 months, subjects who followed MD integrated with virgin olive oil or nuts showed not only a reduction in interleukin-6 and soluble intercellular adhesion molecule-1, significant inflammation mediators in the adhesion of leukocytes to the endothelial”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
