Among these factors, dyslipidemia (i.e., high LDL cholesterol, high lipoprotein (a)) and the activation of specific pro-inflammatory pathways (nucleotide-binding oligomerization domain-like receptor containing pyrin domain 3 inflammasome and Toll-like receptor 4) appear to play a pivotal role in the progression of BAV-associated diseases.
Further, qRT-PCR and ChIP analyses showed lower expression of miR-200c, higher expression of miR-200 target genes, ZEB1/ZEB2 transcription factors, and higher chromatin occupancy of the miR-200c promoter by ZEB1/ZEB2 in BAV patients, indicating a miR-200c/ZEBs negative feedback loop and induction of endothelial/epithelial mesenchymal transition (EndMT/EMT).
This study aimed to investigate the diagnostic influence and surgical predictive effect of NLR and CRP on CAVD.A total of 278 consecutive patients with CAVD (123 patients with bicuspid aortic valve and others with tricuspid aortic valve) and 108 healthy individuals who were included in the control group were enrolled in the study.
We propose that a miR-200-dependent process of EndMT/EMT is a plausible biological mechanism rendering the BAV ascending aorta more prone to aneurysm development.
This revealed a suggestive genetic role for TBX20 in BAV/TAA aetiology, further reinforced by segregation of a rare TBX20 variant with the phenotype within a BAV/TAA family.
A total of 1796 protein and 75 phosphoprotein accession numbers were detected, of which 34 proteins and one phosphoprotein (SSH3) were differentially expressed in BAV patients compared to TAV patients.
Upstream analysis of AP-1 regulation showed that the ERK1/2 signaling pathway is dysregulated and thus represents a novel chain of mediators of aortic dilatation in BAV which should be considered in future studies.

In this review, we focused on interactions and transitions between aforementioned mechanisms demarcating ascending stages of CAVD, suggesting a predisposing condition (bicuspid aortic valve) and drug combination (lipid-lowering drugs combined with angiotensin II antagonists and cytokine inhibitors) for the further testing in both preclinical and clinical trials.
