circRNA-disease information
Expression pattern:
UP
Associated gene: FRS2, CyclinD1, Vimentin, Ago2
Associated microRNA: miR-424-5p
Biological function: Promotes ox-LDL-induced VSMC viability, proliferation, invasion and migration; circ_0004872 knockdown restrains these ox-LDL-stimulated VSMC dysfunction phenotypes.
Molecular mechanism: circ_0004872 acts as a ceRNA sponge for miR-424-5p, thereby elevating FRS2 expression and promoting ox-LDL-induced VSMC dysfunction.
Biological pathway or process:

proliferation (promotes); migration (promotes); invasion (promotes); ceRNA regulation (other)

Detected method:
Q
Validation methods:

RNase R Treatment; RT-qPCR; Nuclear-Cytoplasmic Fractionation; Clinical Sample Validation; RIP (RNA Immunoprecipitation); Luciferase Reporter Assay; Transfection; CCK8; EdU Staining; Transwell Assay; Wound Healing Assay; Western Blot; ROC Analysis; Bioinformatics Analysis

Clinical significance:

circ_0004872 was elevated in AS patient serum and had diagnostic value by ROC analysis; it may be a potential molecular target for AS treatment.

Description:

circ_0004872 is up-regulated in serum from AS patients and in ox-LDL-treated VSMCs. It promotes ox-LDL-induced VSMC proliferation, invasion and migration by sponging miR-424-5p and increasing FRS2 expression, suggesting diagnostic and therapeutic relevance in AS.

Confidence score:

0.817

Title:
