circRNA-disease information
Expression pattern:
DN
Associated gene: FMRP, TFAP2A, Vimentin
Associated microRNA: miR-576-5p
Biological function: Inhibits CRC cell proliferation, migration, EMT, invasion and metastasis; overexpression suppresses tumor growth in vivo.
Molecular mechanism: circ_0009022 acts as a ceRNA for miR-576-5p to regulate TFAP2A and binds the RBP FMRP, reducing Vimentin expression and inhibiting EMT.
Biological pathway or process:

proliferation (inhibits); migration (inhibits); invasion (inhibits); metastasis (inhibits); EMT (inhibits); ceRNA regulation (other)

Detected method:
Q
S
Validation methods:

circRNA-seq; RT-qPCR; FISH / smFISH; Clinical Sample Validation; Bioinformatics Analysis; Transfection; CCK8; Colony Formation Assay; Wound Healing Assay; Transwell Assay; Western Blot; In Vivo Animal Model; H&E Staining; IHC (Immunohistochemistry); IF (Immunofluorescence); RIP (RNA Immunoprecipitation); Luciferase Reporter Assay; RNA Pull-Down; Co-IP

Clinical significance:

circ_0009022 is negatively associated with tumor growth, invasion, metastasis and outcomes, and may serve as a potential biomarker and therapeutic target for CRC.

Description:

hsa_circ_0009022/circ_0009022 is down-regulated in CRC tissues and cell lines and acts as a tumor-suppressive circRNA. It inhibits proliferation, migration, metastasis and EMT by sponging miR-576-5p to regulate TFAP2A and by binding FMRP to reduce Vimentin-related EMT activity. The study suggests circ_0009022 may be a potential biomarker and therapeutic target for CRC.

Confidence score:

0.8388
