Heterozygosity for ADP-ribosylation factor 6 suppresses the burden and severity of atherosclerosis
PLoS One. 2023 May 10;18(5):e0285253. doi: 10.1371/journal.pone.0285253. eCollection 2023.ABSTRACTAtherosclerosis is the root cause of major cardiovascular diseases (CVD) such as myocardial infarction and stroke. ADP-ribosylation factor 6 (Arf6) is a ubiquitously expressed GTPase known to be involved in inflammation, vascular permeability and is sensitive to changes in shear stress. Here, using atheroprone, ApoE-/- mice, with a single allele deletion of Arf6 (HET) or wildtype Arf6 (WT), we demonstrate that reduction in Arf6 attenuates atherosclerotic plaque burden and severity. We found that plaque burden in the descending...

The role of gut-dependent molecule trimethylamine N-oxide as a novel target for the treatment of chronic kidney disease
Int Urol Nephrol. 2023 Feb 16. doi: 10.1007/s11255-023-03500-9. Online ahead of print.ABSTRACTTrimethylamine N-oxide (TMAO) is an intestinal uremic toxin molecule mainly excreted by the kidney. Therefore, the plasma TMAO concentration is significantly increased in chronic kidney disease (CKD) patients, and plasma TMAO can be cleared by dialysis. Furthermore, TMAO damage the kidney mainly through three mechanisms: oxidative stress, inflammation and endoplasmic reticulum stress. Clinical experiments have indicated that higher TMAO levels are strongly related to the elevated incidence and mortality of cardiovascular (CV) even...

Dog models of human atherosclerotic cardiovascular diseases
Mamm Genome. 2022 Oct 15. doi: 10.1007/s00335-022-09965-w. Online ahead of print.ABSTRACTCardiovascular diseases (CVD) are one of the leading causes of death worldwide. Eighty-five percent of CVD-associated deaths are due to heart attacks and stroke. Atherosclerosis leads to heart attack and stroke through a slow progression of lesion formation and luminal narrowing of arteries. Dogs are similar to humans in terms of their cardiovascular physiology, size, and anatomy. Dog models have been developed to recapitulate the complex phenotype of human patients and understand the underlying mechanism of CVD. Different methods, inc...

Diet, microparticles and atherothrombosis.
Abstract Cardiovascular disease is the main cause of death worldwide, and is principally caused by atherosclerosis, with subsequent thrombus formation, eventually provoking an acute myocardial infarction or a stroke. The formation and progression of the atherosclerotic plaques responds to multiple factors including certain diets. Intensive research has elucidated the role of diet in cardiovascular disease and has led to public health policies focusing on educating the population on the role of nutrition in cardiovascular health. Compelling evidence shows that a healthy diet, rich in fruit and vegetables with moder...
