circRNA-disease information
Expression pattern:
UP
Associated gene: -
Associated microRNA: miR-124
Biological function: circ_0000502 promotes HCC cell proliferation, invasion, migration and metastasis, and inhibits apoptosis; knockdown of circ_0000502 reduces proliferation, invasion and migration and promotes apoptosis.
Molecular mechanism: circ_0000502 promotes malignant progression of HCC by targeting, binding to and negatively regulating miR-124, consistent with a miRNA sponge/ceRNA-related mechanism.
Biological pathway or process:

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

Detected method:
Q
Validation methods:

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

Clinical significance:

High expression of circ_0000502 was significantly positively correlated with poor prognosis of HCC; high expression was associated with lower overall survival and worse prognosis.

Description:

circ_0000502 is up-regulated in HCC tissues and cell lines and its high expression is associated with poor prognosis. Functionally, circ_0000502 promotes HCC proliferation, invasion, migration and metastasis while inhibiting apoptosis. Mechanistically, it directly targets and negatively regulates miR-124, and miR-124 can counteract the effects of circ_0000502 in HCC cells.

Confidence score:

0.7078
