| Disease Name: | Aortic Aneurysm, Abdominal |
| Sample: | human and mouse abdominal aortic samples |
| Dysfunction Pattern: | Interaction(miR-204-5p/Mekk3/NF-κB pathway) |
| Validated Method: | RNA Pull-Down//Western Blot//ISH//qRT-PCR//Luciferase Report Assay |
| Description: | An analysis of human and mouse abdominal aortic samples revealed that the lincRNA-p21 levels were significantly higher in AAA tissue. Collectively, the results indicated that ROS-induced lincRNA-p21 sponges miR-204-5p to accelerate synthetic and proinflammatory SMC phenotypes through the Mekk3/NF-κB pathway in AAA formation. Thus, lincRNA-p21 may have therapeutic potential for AAA formation. |
| Causality: | Yes |
| Causal Description: | Stimulation with hydrogen peroxide upregulated the expression of lincRNA-p21 in a dose-dependent manner and converted SMCs from a contractile phenotype to a synthetic, proteolytic, and proinflammatory phenotype in vitro. Moreover, lincRNA-p21 promoted fracture of elastic fibres, reconstruction of the vascular wall, and AAA formation in vivo by modulating SMC phenotypic switching in two mouse models of AAA induced by angiotensin II or porcine pancreatic elastase (PPE) perfusion. |
