circRNA-disease information
Expression pattern:
DN
Associated gene: E-cadherin, N-cadherin, vimentin, CyB1, CyD1
Associated microRNA: miR-532-3p
Biological function: Suppresses breast cancer cell proliferation, migration and invasion; induces G2/M arrest; inhibits EMT.
Molecular mechanism: Acts as a miRNA sponge for miR-532-3p; miR-532-3p mimics reverse circRNA_103809-mediated anti-tumor effects; associated with EMT marker changes.
Biological pathway or process:

proliferation (inhibits); cell cycle (other); migration (inhibits); invasion (inhibits); EMT (inhibits); ceRNA regulation (other)

Detected method:
Q
Validation methods:

RT-qPCR; Clinical Sample Validation; Survival Analysis; Bioinformatics Analysis; Luciferase Reporter Assay; Transfection; CCK8; Cell Cycle Assay; Transwell Assay; Western Blot

Clinical significance:

Low circRNA_103809 expression is associated with distant metastasis, HER-2 status, TNM stage, and shorter overall survival; circRNA_103809 may be a prospective biomarker/therapeutic target.

Description:

In breast cancer, circRNA_103809 is down-regulated and functions as a tumor suppressor. Its overexpression inhibits proliferation and migration/invasion, induces G2/M arrest, and suppresses EMT, at least partly by sponging miR-532-3p; higher circRNA_103809 expression is associated with better overall survival.

Confidence score:

0.7113
