circRNA-disease information
Expression pattern:
UP
Associated gene: hTERT, AGO2, FMN2
Associated microRNA: miR-1182
Biological function: Promotes CRC cell proliferation, migration, tumor growth, cell cycle progression and tumorigenesis; knockdown inhibits proliferation and migration in vitro and tumor growth in vivo.
Molecular mechanism: circFMN2 acts as a ceRNA sponge for miR-1182 and up-regulates hTERT expression through the circFMN2/miR-1182/hTERT axis.
Biological pathway or process:

ceRNA regulation (promotes); proliferation (promotes); migration (promotes); metastasis (promotes); cell cycle (promotes); apoptosis (other); other pathway/process (promotes)

Detected method:
Q
M
Validation methods:

Back-Splice Junction PCR / divergent primers PCR; RNase R Treatment; RT-qPCR; Microarray; Clinical Sample Validation; Bioinformatics Analysis; circRIP; RIP (RNA Immunoprecipitation); Luciferase Reporter Assay; Transfection; CCK8; Colony Formation Assay; Cell Cycle Assay; Annexin V/PI Flow Cytometry; Western Blot; IHC (Immunohistochemistry); In Vivo Animal Model

Clinical significance:

High circFMN2 expression is associated with larger tumor size, advanced tumor stage, distant metastasis and TNM stage; serum exosomal circFMN2 may be a novel clinical molecular marker, biomarker and therapeutic target for CRC.

Description:

circFMN2 is an up-regulated oncogenic circRNA in CRC tissues, cell lines and serum exosomes. It promotes CRC proliferation, cell cycle progression, migration and xenograft tumor growth mainly by sponging miR-1182 and increasing hTERT expression, and it may serve as a biomarker and therapeutic target.

Confidence score:

0.8571
