circRNA-disease information
Expression pattern:
DN
Associated gene: PTEN, AGO2
Associated microRNA: miR-25-3p
Biological function: inhibits proliferation and invasion; suppresses tumor growth in vivo
Molecular mechanism: Exosomal circBTG2 acts as a ceRNA/miRNA sponge for miR-25-3p, relieving repression of PTEN.
Biological pathway or process:

proliferation (inhibits); invasion (inhibits); ceRNA regulation (promotes)

Detected method:
Q
M
Validation methods:

Microarray; RNase R Treatment; RT-qPCR; Clinical Sample Validation; Bioinformatics Analysis; Luciferase Reporter Assay; RIP (RNA Immunoprecipitation); Transfection; CCK8; EdU Staining; Transwell Assay; Western Blot; In Vivo Animal Model

Clinical significance:

circBTG2 is probably a diagnostic biomarker and potential target for glioma therapy.

Description:

This study identifies exosomal circBTG2 (derived from BTG2) as a suppressor of glioma progression. circBTG2 inhibits glioma cell proliferation and invasion and suppresses xenograft growth by sponging miR-25-3p to increase PTEN expression, suggesting potential diagnostic/therapeutic value.

Confidence score:

0.7795
