Abstract
Ivabradine, a heart rate reducing agent, protects the vascular system by unidentified mechanisms. We sought to determine the effects of the treatment with ivabradine, started before plaque formation, on early transcriptional changes and endothelium lesions in regions of aorta subjected to disturbed blood flow. Six week-old apolipoprotein E-deficient (ApoE-/-) mice, fed a low-fat diet, were treated with ivabradine to determine the effect on transcriptional changes (2-and 4-week treatment) and on lesions formation (19-week treatment) in the endothelium of the aortic arch. Microarrays analysis (60k probes) of endothelium-enriched RNA was carried out to detect changes in gene expression induced by treatment. Endothelium damage was assessed by en-face immunofluorescence staining for vascular endothelial (VE) cadherin. According to microarray analysis, 930 transcripts were affected by the treatment. We found downregulation of pro-apoptotic and pro-inflammatory genes, the majority of which are nuclear factor-κB (NF-κB)-and/or angiotensin II-regulated genes, and upregulation of anti-inflammatory genes. Many shear stress-responsive genes were affected by the treatment and the MAPK, Notch signalling and sterol metabolic processes were among the most significantly affected pathways. Consistently, we observed increased levels of Hes5, a Notch target gene, together with a reduction of endothelium damage, in the lower aortic arch of treated- compared with untreated- mice. We concluded that an early treatment with ivabradine protected the endothelium of the aortic arch of ApoE-/- mice. Activation of the Notch signalling could be part of the mechanism underlying this protection.

Abstract
BACKGROUND AND AIMS Oxidized LDL (oxLDL) or pro-inflammatory stimuli lead to increased oxidative stress linked to endothelial dysfunction and atherosclerosis. The oxLDL receptor-1 (LOX1) is elevated within atheromas and cholesterol-lowering statins inhibit LOX1 expression. Berberine (BBR), an alkaloid extracted from plants of gender Berberis, has lipid-lowering and anti-inflammatory activity. However, its role in regulating LOX1-mediated signaling is still unknown. The aim of this study was to investigate the effect of BBR on oxLDL- and TNFα-induced endothelial dysfunction in human umbilical vein endothelial cells (HUVECs) and to compare it with that of lovastatin (LOVA). METHODS AND RESULTS Cytotoxicity was determined by lactate dehydrogenase assay. Antioxidant capacity was measured with chemiluminescent and fluorescent method and intracellular ROS levels through a fluorescent dye. Gene and protein expression levels were assayed by qRT-PCR and western blot, respectively. HUVECs exposure to oxLDL (30 μg/ml) or TNFα (10 ng/ml) for 24 h led to a significant increase in LOX1 expression, effect abrogated by BBR (5 μM) and LOVA (5 μM). BBR but not LOVA treatment abolished the TNFα-induced cytotoxicity and restored the activation of Akt signaling. In spite of a low direct antioxidant capacity, both compounds reduced intracellular ROS levels generated by treatment of TNFα but only BBR inhibited NOX2 expression, MAPK/Erk1/2 signaling and subsequent NF-κB target genes VCAM and ICAM expression, induced by TNFα. CONCLUSIONS These findings demonstrated for the first time that BBR could prevent the oxLDL and TNFα - induced LOX1 expression and oxidative stress, key events that lead to NOX, MAPK/Erk1/2 and NF-κB activation linked to endothelial dysfunction. CHEMICAL COMPOUNDS STUDIED IN THIS ARTICLE Berberine (PubChem CID: 2353); Lovastatin (PubChem CID: 53232).
