circRNA-disease information
Expression pattern:
UP
Associated gene: PLK2, TAp73
Associated microRNA: miR-520g-3p
Biological function: Suppresses osteosarcoma progression; inhibits proliferation, migration and invasion; promotes apoptosis; affects cell cycle (G2 phase arrest upon silencing).
Molecular mechanism: Acts as a sponge (ceRNA) for miR-520g-3p to regulate PLK2 (and TAp73) expression.
Biological pathway or process:

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

Detected method:
Q
Validation methods:

RT-qPCR; RNA Pull-Down; Luciferase Reporter Assay; Transfection; CCK8; Annexin V/PI Flow Cytometry; Cell Cycle Assay; Transwell Assay; Western Blot; In Vivo Animal Model; Bioinformatics Analysis

Clinical significance:

-

Description:

This study shows circ_0102049 acts as a tumor suppressor in osteosarcoma models. Silencing circ_0102049 promotes tumor growth and enhances MG63 cell proliferation, migration and invasion while reducing apoptosis, mainly through a ceRNA mechanism involving miR-520g-3p and downstream PLK2 (and TAp73).

Confidence score:

0.6276
