circRNA-disease information
Expression pattern:
DN
Associated gene: TJP1, CDH2, VIM
Associated microRNA: hsa-miR-24-3p, hsa-miR-138-5p, hsa-miR-145-3p, hsa-miR-620, hsa-miR-875-3p
Biological function: Suppresses HCC cell migration and invasion; induces cell cycle arrest (G2/M) without significantly affecting apoptosis; encodes a protein.
Molecular mechanism: May act through a ceRNA network (circEPS15-miRNA-mRNA); modulates TJP1/CDH2/VIM signaling; contains a spanning junction ORF with IRES-driven translation to produce a novel protein.
Biological pathway or process:

Notch (other); inflammation (other); cell cycle (inhibits); migration (inhibits); invasion (inhibits); ceRNA regulation (other)

Detected method:
Q
M
Validation methods:

Microarray; RNase R Treatment; RT-qPCR; Back-Splice Junction PCR / divergent primers PCR; Clinical Sample Validation; ROC Analysis; Survival Analysis; Transfection; Wound Healing Assay; Transwell Assay; Cell Cycle Assay; Annexin V/PI Flow Cytometry; Western Blot; Luciferase Reporter Assay; Bioinformatics Analysis

Clinical significance:

Low circEPS15 levels were significantly associated with poor overall survival; circEPS15 showed diagnostic significance for HCC (AUC = 0.735).

Description:

circEPS15 (circRNA-100226) is down-regulated in HCC tissues and low expression is associated with poor overall survival. circEPS15 overexpression inhibits HCC cell migration/invasion and induces G2/M cell-cycle arrest, potentially via a ceRNA network and modulation of TJP1/CDH2/VIM signaling. It also contains an IRES-driven spanning-junction ORF that can be translated into a novel protein.

Confidence score:

0.835
