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...

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...

TranscriptomicsMiRNA microarray analysis of human bicuspid and tricuspid aortic valve leaflet tissues
Bicuspid aortic valve (BAV) is a common congenital cardiac anomaly, with an estimated incidence of 1-2%. It is responsible for the greatest burden of aortic valve disease in patients younger than 70 years in North America. We performed microRNA profiling in end-stage valve leaflets with BAV and TA...

TranscriptomicsAdvanced Study of Aortic Pathology (ASAP)
BACKGROUND: The vast majority of thoracic aortic aneurysms (TAAs) are observed either together with a bicuspid aortic valve (BAV), a common congenital disorder, or in idiopathic cases such as patients with a normal tricuspid aortic valve (TAV). The main objective of our study was to identify shared ...

ProteomicsAortic smooth muscle cells in bicuspid valve patients
and with higher incidence if associated to bicuspid aortic valve (BAV) for unknown reasons. TAA is usually diagnosed fortuitously and the lack of effective drug therapy to delay progression and avoid dissection lies in the limited knowledge of pathophysiology. Objectives. We aimed to identify the mo...

TranscriptomicsThe long non-coding HOTAIR is modulated by cyclic stretch and WNT/beta-CATENIN in human aortic valve cells and is a novel repressor of calcification genes
Aortic valve calcification is a significant and serious clinical problem for which there are no effective medical treatments. Individuals born with bicuspid aortic valves, 1-2% of the population, are at the highest risk of developing aortic valve calcification. Aortic valve calcification involves in...

TranscriptomicsStretch responsive miRNAs in human aortic valve interstitial cells
miRNA-Sequencing was performed on human aortic valve interestitial cells (AVICs) exposed to 14% stretch at 1 hz or static conditions for 24h. Six static control and six samples exposed to cyclic stretch 14% for 24h

ProteomicsThe extracellular matrix landscape identifies different etiologies behind bicuspid and tricuspid aortic valve degeneration
The molecular basis of aortic valve degeneration (AVD) is unclear. The extracellular matrix (ECM) of the valve is in dynamic reciprocity with its surrounding microenvironment and contains molecular traits of the pathophysiological processes. We compared abundances of ECM proteins from excised valve ...
