circRNA-disease information
Expression pattern:
UP
Associated gene: ERBB4
Associated microRNA: miR-1304
Biological function: circ_0074026 promotes glioma cell growth, migration and invasion, inhibits apoptosis, and facilitates oncogenesis and tumor progression.
Molecular mechanism: circ_0074026 functions as a miR-1304 sponge to positively regulate ERBB4 expression, thereby promoting glioma progression.
Biological pathway or process:

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

Detected method:
Q
Validation methods:

RT-qPCR; Clinical Sample Validation; Transfection; CCK8; Annexin V/PI Flow Cytometry; Wound Healing Assay; Transwell Assay; Luciferase Reporter Assay; Western Blot; Survival Analysis; Bioinformatics Analysis

Clinical significance:

High circ_0074026 expression is associated with larger tumor size, higher WHO grade, worse overall survival, worse disease-free survival, and may act as an independent prognostic predictor in glioma.

Description:

circ_0074026 is up-regulated in glioma tissues and cell lines, and high expression predicts unfavorable prognosis. Functionally, circ_0074026 promotes glioma cell proliferation, migration and invasion while inhibiting apoptosis. Mechanistically, it sponges miR-1304 to upregulate ERBB4 expression and thereby facilitates glioma progression.

Confidence score:

0.7126

Other information
Title:

Circular RNA circ_0074026 indicates unfavorable prognosis for patients with glioma and facilitates oncogenesis of tumor cells by targeting miR-1304 to modulate ERBB4 expression.
