circRNA-disease information
Expression pattern:
UP
Associated gene: X-linked inhibitor of apoptosis / XIAP
Associated microRNA: miR-142-3p
Biological function: Promotes colorectal cancer cell proliferation, migration and invasion, and inhibits apoptosis; associated with enlarged tumour volume and advanced TNM stage.
Molecular mechanism: Circ_0006174 acts as a ceRNA by sponging miR-142-3p, thereby positively regulating XIAP expression.
Biological pathway or process:

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

Detected method:
Q
M
Validation methods:

RT-qPCR; Clinical Sample Validation; Nuclear-Cytoplasmic Fractionation; Transfection; CCK8; BrdU; Annexin V/PI Flow Cytometry; Transwell Assay; Luciferase Reporter Assay; RIP (RNA Immunoprecipitation); Western Blot; Bioinformatics Analysis

Clinical significance:

High expression was associated with enlarged tumour volume and advanced TNM stage; the study suggests potential diagnostic biomarker and therapeutic target value.

Description:

Circ_0006174 is an up-regulated RAD23B-derived circRNA in human colorectal cancer tissues and cell lines. It functions as an oncogenic circRNA that promotes proliferation, migration and invasion while suppressing apoptosis, mainly through sponging miR-142-3p and increasing XIAP expression. Its high expression is associated with unfavorable clinicopathological characteristics, including enlarged tumor volume and advanced TNM stage.

Confidence score:

0.7295
