circRNA-disease information
Expression pattern:
UP
Associated gene: beta-catenin
Associated microRNA: -
Biological function: Promotes CRC cell stemness, sphere formation, migration, metastasis and tumorigenesis.
Molecular mechanism: circ-ABCC1 binds beta-catenin, promotes beta-catenin nuclear accumulation, and activates the Wnt/beta-catenin pathway; exosomes from CD133+ cells carry circ-ABCC1.
Biological pathway or process:

Wnt/beta-catenin (promotes); stemness (promotes); migration (promotes); metastasis (promotes); other pathway/process (promotes)

Detected method:
Q
M
Validation methods:

Bioinformatics Analysis; Back-Splice Junction PCR / divergent primers PCR; Actinomycin D / DRB Stability Assay; RNase R Treatment; RT-qPCR; Transfection; Flow Cytometry(Non-apoptosis/cycle); Transwell Assay; Western Blot; Nuclear-Cytoplasmic Fractionation; FISH / smFISH; RIP (RNA Immunoprecipitation); RNA Pull-Down

Clinical significance:

circ-ABCC1 serves as a novel candidate target for CRC treatment and may be utilized as a biomarker in CRC research works.

Description:

This study identifies hsa_circ_0000677 (circ-ABCC1) as an upregulated exosomal circRNA in CRC. circ-ABCC1 promotes CRC cell stemness, sphere formation, migration and metastasis, and mechanistically binds beta-catenin to enhance its nuclear accumulation and activate the Wnt/beta-catenin pathway. The authors propose circ-ABCC1 as a potential therapeutic target or biomarker candidate for CRC research.

Confidence score:

0.7884
