MetabolomicsMetabolomics Characterization of Human Calcific Aortic Valve Stenosis

BACKGROUND: Calcific aortic valve stenosis (CAVS) is the most prevalent valvular heart disease in developed countries with significant morbidity and mortality. Given the poor understanding of the pathophysiological processes leading to CAVS, we utilized a joint non-targeted metab...

MetabolomicsValvular lipidomic changes in progression of human calcific aortic valve stenosis
This study investigates lipid dysregulation in calcific aortic valve stenosis (CAVS) by analyzing lipid profiles in valve tissues from 99 patients across different disease severities (mild, moderate, severe) using liquid chromatography-mass spectrometry (LC-MS). The results reveal distinct lipid alt...

TranscriptomicsTranscription profiling of human patients with aortic aneurysms associated with tricuspid and bicuspid valves
Patients with bicuspid aortic valve (BAV) have increased risk of thoracic ascending aortic aneurysm (AscAA) and dissection compared to those with a normal tricuspid aortic valve (TAV). The present study was undertaken to evaluate whether differences in gene expression exist in aortas from BAV and TA...

TranscriptomicsGene expression from healthy male and female porcine aortic valve leaflets
Calcific aortic valvular disease (CAVD) is characterized by sclerosis of the aortic valve leaflets and recent clinical studies have linked several other risk factors to this disease, including male sex. In this study we examined potential sex-related differences in gene expression profiles between ...

TranscriptomicsAortic valve transcriptome in CHIP, non-CHIP and non-calcific controls.
The aim of the present study was to gain insights on the pathological process of Calcific Aortic Valve Disease in CHIP carriers. To uncover molecular pathways that could link CHIP to CAVD, we exanimated the aortic valve transcriptome from CHIP, non-CHIP patients, or non-calcific controls with RNAseq...

ProteomicsAortic Aneurysm iTRAQ HiRIEF proteomics
Conducted proteomics on samples from patients with aortic aneurysm and from non-dilated controls. Furthermore, we investigated both patients with bicuspid aortic valves (BAV) and also the more normal tricuspid aortic valves (TAV). The aim was to elucidate the molecular mechanisms behind the higher p...

MetabolomicsMitochondrial NAD+ Deficiency in Vascular Smooth Muscle Impairs Collagen III Turnover to Trigger Aortic Disease

Aortic disease poses a significant mortality risk in adults, yet many of its underlying factors remain undiscovered. In this study, we identify mitochondrial NAD⁺ deficiency as a causal factor. Metabolomics analysis of 73 surgical aortic specimens revealed impaired NAD⁺ salvage and mitochondrial ...

ProteomicsMitochondrial extracellular vesicles promote aortic valve calcification via carnitine O-octanoyltransferase
Calcific aortic valve disease (CAVD) is a leading cause of cardiovascular morbidity and mortality with no effective medical therapy. We previously identified carnitine O-octanoyltransferase (CROT) as a mediator of mitochondrial dysfunction and vascular calcification. However, its role in CAVD remain...

TranscriptomicsInhibitory Role of Notch1 in Calcific Aortic Valve Disease
Aortic valve calcification is the most common form of valvular heart disease, but the mechanisms of calcific aortic valve disease (CAVD) are unknown. NOTCH1 mutations are associated with aortic valve malformations and adult-onset calcification in families with inherited disease. The Notch signaling ...
