circRNA-disease information
Expression pattern:
UP
Associated gene: CCND1, P53, P21
Associated microRNA: miR-138-5p
Biological function: Promotes AVIC calcification, calcium nodule formation, osteogenic differentiation, ALP activity, and expression of osteogenic differentiation-related proteins and CCND1/P53/P21 pathway proteins.
Molecular mechanism: circ-CCND1 acts as a sponge for miR-138-5p to regulate CCND1 expression and activate the CCND1/P53/P21 signaling pathway.
Biological pathway or process:

p53 signaling (promotes); ceRNA regulation (promotes); other pathway/process (promotes)

Detected method:
Q
M
Validation methods:

RT-qPCR; Clinical Sample Validation; Bioinformatics Analysis; Transfection; Luciferase Reporter Assay; RNA Pull-Down; Western Blot

Clinical significance:

circ-CCND1 can be used as a diagnostic marker for CAVD and may be a molecular target for the treatment of CAVD.

Description:

circ-CCND1 is up-regulated in calcified aortic valve leaflets and promotes calcification and osteogenic differentiation of valve interstitial cells. Mechanistically, it sponges miR-138-5p to regulate CCND1 and activate the CCND1/P53/P21 pathway, suggesting potential diagnostic and therapeutic relevance in CAVD.

Confidence score:

0.6675

Other information
Title:

circ-CCND1 regulates the CCND1/P53/P21 pathway through sponging miR-138-5p in valve interstitial cells to aggravate aortic valve calcification.
