circRNA-disease information
Expression pattern:
UP
Associated gene: CXCL5, Ago2
Associated microRNA: miR-363-3p
Biological function: Promotes proliferation, cell cycle progression, migration and invasion, and inhibits apoptosis in colorectal cancer cells; promotes tumor growth in vivo.
Molecular mechanism: Acts as a ceRNA to sponge miR-363-3p, thereby relieving miR-363-3p-mediated suppression and promoting CXCL5 expression.
Biological pathway or process:

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

Detected method:
Q
Validation methods:

RT-qPCR; RNase R Treatment; Nuclear-Cytoplasmic Fractionation; Transfection; Luciferase Reporter Assay; RIP (RNA Immunoprecipitation); CCK8; Colony Formation Assay; Annexin V/PI Flow Cytometry; Cell Cycle Assay; Transwell Assay; Western Blot; In Vivo Animal Model; Clinical Sample Validation; Bioinformatics Analysis

Clinical significance:

CircCTNNA1 may serve as a biomarker of CRC.

Description:

circCTNNA1 is up-regulated in colorectal cancer tissues and cell lines and mainly localizes to the cytoplasm. It promotes CRC malignant phenotypes and tumor growth by acting as a ceRNA that sponges miR-363-3p, thereby increasing CXCL5 expression.

Confidence score:

0.78

Other information
Title:

CircCTNNA1 acts as a ceRNA for miR-363-3p to facilitate the progression of colorectal cancer by promoting CXCL5 expression.
