circRNA-disease information
Expression pattern:
UP
Associated gene: CBX8
Associated microRNA: miR-518d-5p/519-5p family, miR-519a-5p, miR-519c-5p, miR-518e-5p
Biological function: Promotes cervical cancer cell proliferation, cell cycle progression, migration and invasion; knockdown inhibits proliferation, migration and invasion and increases G0/G1 arrest.
Molecular mechanism: circRNA8924 functions as a competitive endogenous RNA by sponging the miR-518d-5p/519-5p family, thereby relieving miRNA-mediated repression of CBX8 and upregulating CBX8 expression.
Biological pathway or process:

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

Detected method:
Q
M
Validation methods:

Back-Splice Junction PCR / divergent primers PCR; RT-qPCR; Microarray; Clinical Sample Validation; Transfection; CCK8; Transwell Assay; Cell Cycle Assay; Luciferase Reporter Assay; Western Blot; Bioinformatics Analysis

Clinical significance:

High circRNA8924 expression is associated with tumor size, FIGO staging and myometrial invasion, and may serve as a biomarker for cervical cancer diagnosis and disease progression.

Description:

circRNA8924 is up-regulated in cervical cancer tissues and correlates with more aggressive clinicopathological features. It promotes cervical cancer cell proliferation, cell cycle progression, migration and invasion by acting as a ceRNA for the miR-518d-5p/519-5p family and increasing CBX8 expression. The study proposes circRNA8924 as a potential diagnostic/progression biomarker and therapeutic target in cervical cancer.

Confidence score:

0.7404
