circRNA-disease information
Expression pattern:
UP
Associated gene: ICAM1, USP36
Associated microRNA: miR-491-5p
Biological function: Circ_0003204 promotes ox-LDL-induced endothelial cell injuries, including inflammation, cell apoptosis, reduced cell viability, and impaired tube formation; circ_0003204 knockdown protects HUVECs against these injuries.
Molecular mechanism: Circ_0003204 acts as a ceRNA/miR-491-5p sponge to positively regulate ICAM1 expression, thereby modulating ox-LDL-induced HUVEC injuries.
Biological pathway or process:

ceRNA regulation (promotes); inflammation (promotes); apoptosis (promotes); angiogenesis (inhibits); other pathway/process (promotes)

Detected method:
Q
Validation methods:

RT-qPCR; RNase R Treatment; Actinomycin D / DRB Stability Assay; Transfection; ELISA; CCK8; Annexin V/PI Flow Cytometry; Tube Formation Assay; Western Blot; Luciferase Reporter Assay; RIP (RNA Immunoprecipitation); Bioinformatics Analysis

Clinical significance:

Circ_0003204 inhibition might prevent AS development.

Description:

Circ_0003204 is up-regulated in ox-LDL-treated HUVECs, an in vitro model relevant to atherosclerosis. Its knockdown protects endothelial cells by reducing inflammation and apoptosis while restoring cell viability and tube formation. Mechanistically, circ_0003204 functions as a miR-491-5p sponge to up-regulate ICAM1 through the circ_0003204/miR-491-5p/ICAM1 axis.

Confidence score:

0.7406

Title:

Circ_0003204 knockdown protects endothelial cells against oxidized low-density lipoprotein-induced injuries by targeting the miR-491-5p-ICAM1 pathway.
