circRNA-disease information
Expression pattern:
UP
Associated gene: YTHDF2
Associated microRNA: -
Biological function: promotes glioblastoma tumorigenesis and stem cell malignancy by activating MET signaling
Molecular mechanism: circMET is an m6A-modified coding circRNA; YTHDF2 facilitates its translation into MET404, which activates MET signaling independent of HGF
Biological pathway or process:

ceRNA regulation (not specified); other pathway/process (promotes)

Detected method:
Q
B
S
Validation methods:

Back-Splice Junction PCR / divergent primers PCR; Sanger Sequencing; RNase R Treatment; Actinomycin D / DRB Stability Assay; RT-qPCR; Northern Blot; FISH / smFISH; Nuclear-Cytoplasmic Fractionation; Clinical Sample Validation; RNA-seq; Bioinformatics Analysis; MeRIP / MeRIP-seq; RIP (RNA Immunoprecipitation); Luciferase Reporter Assay; Transfection; CCK8; EdU Staining; In Vivo Animal Model; H&E Staining; IHC (Immunohistochemistry); IF (Immunofluorescence); Western Blot; ELISA; Co-IP; RNA Pull-Down

Clinical significance:

High MET404 expression predicted worse overall survival of GBM patients

Description:

This study identifies circMET as an m6A-modified circular RNA from the MET gene that is highly expressed in GBM/GSCs. circMET interacts with the m6A reader YTHDF2 to facilitate translation of the MET404 protein, which drives GBM tumorigenesis by constitutively activating MET signaling independent of HGF.

Confidence score:

0.8886
