circRNA-disease information
Expression pattern:
UP
Associated gene: PFN2, PAX5, AGO2, TGF-beta1, Smad2, Smad3
Associated microRNA: miR-183-5p
Biological function: promotes proliferation, migration, invasion, EMT, and liver metastasis of CRC cells
Molecular mechanism: PAX5-induced upregulation of circ0020134; circ0020134 sponges miR-183-5p to upregulate PFN2 and activate the TGF-beta/Smad pathway, promoting EMT and metastasis
Biological pathway or process:

TGF-beta/SMAD (promotes); EMT (promotes); proliferation (promotes); migration (promotes); invasion (promotes); metastasis (promotes); ceRNA regulation (promotes)

Detected method:
Q
S
Validation methods:

RNA-seq; RT-qPCR; Back-Splice Junction PCR / divergent primers PCR; Sanger Sequencing; RNase R Treatment; FISH / smFISH; Nuclear-Cytoplasmic Fractionation; RIP (RNA Immunoprecipitation); RNA Pull-Down; Luciferase Reporter Assay; Transfection; CCK8; Colony Formation Assay; Transwell Assay; Western Blot; In Vivo Animal Model; IHC (Immunohistochemistry); H&E Staining; Survival Analysis; Bioinformatics Analysis; Clinical Sample Validation; Cohort Study

Clinical significance:

High circ0020134 levels were associated with poor prognosis (worse 5-year OS) in CRC patients.

Description:

hsa_circ_0020134 (circ0020134), derived from CACUL1, is up-regulated in CRC liver metastases and is associated with worse overall survival. It promotes CRC proliferation and metastasis by sponging miR-183-5p to increase PFN2 expression, activating TGF-beta/Smad signaling and EMT; its expression is transcriptionally induced by PAX5.

Confidence score:

0.8941
