circRNA-disease information
Expression pattern:
DN
Associated gene: PTEN, AGO2
Associated microRNA: miR-23a-3p
Biological function: circFBXW7 overexpression inhibits glioma cell proliferation, migration, invasion, tumor growth and metastasis; low circFBXW7 expression is associated with shorter overall survival.
Molecular mechanism: circFBXW7 acts as a ceRNA that sponges miR-23a-3p, thereby increasing PTEN expression and suppressing glioma progression.
Biological pathway or process:

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

Detected method:
Q
Validation methods:

RT-qPCR; Clinical Sample Validation; Transfection; CCK8; Transwell Assay; Luciferase Reporter Assay; RIP (RNA Immunoprecipitation); Western Blot; In Vivo Animal Model; IHC (Immunohistochemistry); Survival Analysis; Bioinformatics Analysis

Clinical significance:

Low circFBXW7 expression is closely related to tumor size and WHO grade, and patients with low circFBXW7 expression had shorter overall survival; circFBXW7 may offer a novel target for clinical therapy and diagnosis of glioma.

Description:

circFBXW7 is downregulated in glioma tissues and cell lines and functions as a tumor-suppressive circRNA. Its overexpression inhibits glioma cell proliferation, migration, invasion, tumor growth and metastasis by sponging miR-23a-3p and increasing PTEN expression. Clinically, lower circFBXW7 expression is associated with larger tumor size, higher WHO grade and shorter overall survival.

Confidence score:

0.7779
