Analysis of aortic valve interstitial cells treated with the Notch1 signaling inhibitor DAPT. NOTCH1 mutations are associated with aortic valve malformations and adult-onset calcification. Results provide insight into the role of Notch in the pathogenesis of calcific aortic valve disease.

(Submitter supplied) 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 pathway is critical for multiple cell differentiation processes, but its role in the development of CAVD is not well understood. more...

(Submitter supplied) Rapacz Familial Hypercholesterolemic (RFH) swine have been used extensively in the vascular biology field as a robust model of complex atherosclerotic lesions. However, the heart valves from RFH swine have not been evaluated and it is unknown whether these animals develop calcific aortic valve disease without dietary intervention. Histological assessment of heart valve leaflets isolated from juvenile and adult swine revealed RFH swine develop the early hallmarks of the disease at two years of age. more...

(Submitter supplied) Introduction: Renal failure is associated with aortic valve calcification. Using our rat model of uraemia-induced reversible aortic valve calcification, we assessed the role of apoptosis and survival pathways in aortic valve calcification. We also explored the effects of raloxifene - an estrogen receptor modulator on valvular calcification. Methods: Gene array analysis was performed in aortic valves obtained from 3 groups of rats (n=7 each): calcified valves from rats fed with uremic diet -high-adenine (0.75%), high-phosphate diet (1.5%), valves after calcification resolution following diet cessation (reversibility) and control. more...

(Submitter supplied) Klotho-deficient mice develop aortic valve annulus calcification by 6 weeks of age. Understanding the molecular basis by which aortic valve calcification is initiated will help define potential molecular targets which may be inhibited to reduce or prevent aortic valve calcification. Changes in gene expression related to aortic valve annulus calcification were analyzed by comparing gene expression in the aortic roots from wild type versus klotho-deficient mice.

(Submitter supplied) Purpose:To explore the the function and underlying mechanisms of basic fibroblast growth factor (BFGF) on calcific aortic valve disease (CAVD) a. Methods: The valvular interstitial cells were isolated from porcine aortic valve leaflets. To investigate the effect of BFGF on osteogenic differentiation of VICs, the osteogenic induced medium (OIM) and BFGF were added. RNA sequencing is used to identify changes in gene proffles. more...

(Submitter supplied) 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 porcine male and female valvular interstitial cells (VICs) to explore possible differences in CAVD propensity on the cellular level.

(Submitter supplied) Calcific aortic valve disease (CAVD) is an increasingly prevalent condition and endothelial dysfunction is implicated in its etiology. We previously identified nitric oxide (NO) as a calcification inhibitor by its activation of NOTCH1, which is genetically linked to human CAVD. Here, we show that NO rescues calcification by a S-nitrosylation-mediated mechanism in porcine aortic valve interstitial cells (pAVICs) and single cell RNA-seq demonstrated regulation of NOTCH pathway by NO. more...

(Submitter supplied) We have manipulated the NOTCH signaling pathway in mouse embryonic endocardial cells by the co-culture with OP9 stromal cells expressing Jag1 and Dll4, the culture over recombinant JAG1 and DLL4, and the use of the γ-secretase inhibitor RO4929097. We have performed RNA-seq and ATAC-seq to define the transcriptional profile and the chromatin accessibility landscape specific for each condition.
