Disease Name: | Aortic Dissection |
Sample: | thoracic aorta tissues of AD patients |
Dysfunction Pattern: | Interaction(miR-193b-3p) |
Validated Method: | In Vivo Experiment//RNA Pull-Down//Western Blot//Wound Healing Assay//qRT-PCR//RIP//Luciferase Report Assay//Bioinformatics Analysis |
Description: | LncRNA H19 was abnormally high-expressed in thoracic aorta tissues of AD patients, and it could competitively bind to and inhibit miR-193b-3p. |
Causality: | Yes |
Causal Description: | In the PDGF-BB group, the expressions of H19, matrix metallopeptidase (MMP) 2 (MMP-2) and MMP-9 were up-regulated and the expressions of miR-193b-3p, α-SMA, and SM22α were down-regulated; moreover, the proliferation and migration rate of HASMCs were increased. However, H19 silencing reversed the regulation of PDGF-BB on HASMCs. More interestingly, miR-193b-3p inhibitor could partially reverse the effect of H19 silencing. In addition, the above results were verified by animal experiments, showing that shH19 and up-regulated miR-193b-3p could significantly reduce the thoracic aorta pathological damage in AD mice. |
