circRNA-disease information
Expression pattern:
UP
Associated gene: IL11, MFAP2, MMP10, MMP1
Associated microRNA: hsa-miR-369-3p, hsa-miR-3118, hsa-miR-342-3p, hsa-miR-4712-5p, hsa-miR-770-5p, hsa-miR-6865-5p
Biological function: Promotes EMT process in oesophageal cancer (via relieving miRNA-mediated inhibition of EMT-related genes).
Molecular mechanism: QKI-regulated circRNA biogenesis and ceRNA mechanism: hsa_circ_0061395 sponges miRNAs to de-repress IL11/MFAP2/MMP10/MMP1, promoting EMT.
Biological pathway or process:

EMT (promotes); ceRNA regulation (promotes)
Detected method:
S
Validation methods:

RNA-seq; Bioinformatics Analysis
Clinical significance:

-
Description:

In oesophageal cancer, hsa_circ_0061395 (from host gene PTK2) is predicted to be upregulated and promoted by QKI-regulated alternative splicing. It may act as a ceRNA by sponging several miRNAs, thereby de-repressing EMT-related genes (IL11, MFAP2, MMP10, MMP1) and promoting EMT.
Confidence score:

0.1768
