circRNA-disease information
Expression pattern:
UP
Associated gene: EZH2
Associated microRNA: miR-520b
Biological function: circ-TTBK2 promotes glioma cell proliferation and invasion, inhibits apoptosis, and facilitates glioma tumor progression in vivo.
Molecular mechanism: circ-TTBK2 acts as a miR-520b sponge and modulates EZH2 through the circ-TTBK2/miR-520b/EZH2 axis.
Biological pathway or process:

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

Detected method:
Q
Validation methods:

RT-qPCR; Clinical Sample Validation; Bioinformatics Analysis; Luciferase Reporter Assay; Transfection; MTT; Annexin V/PI Flow Cytometry; Transwell Assay; Western Blot; In Vivo Animal Model

Clinical significance:

circ-TTBK2/miR-520b/EZH2 axis might serve as potential targets for glioma diagnosis and therapy.

Description:

This study identifies circ-TTBK2 as an up-regulated oncogenic circRNA in human glioma tissues and cell lines. circ-TTBK2 promotes glioma cell proliferation, invasion, and in vivo tumor growth while suppressing apoptosis, mainly through sponging miR-520b and regulating EZH2 in the circ-TTBK2/miR-520b/EZH2 axis. The axis is proposed as a potential target for glioma diagnosis and therapy.

Confidence score:

0.6536
