circRNA-disease information
Expression pattern:
UP
Associated gene: 2,527 unique genes, MAPK signaling pathway, Ras signaling pathway, Proteoglycans in cancer pathway, cGMP-PKG signaling pathway, axon guidance, cholinergic synapse pathways
Associated microRNA: miR-22-5p, miR-6825-5p, miR-6072, miR-4677-5p, miR-6891-3p, miR-6780a-3p, miR-4494, miR-6728-3p, miR-1226-3p, miR-502-5p
Biological function: May act as a component of universal DNA damage response and link damage response systems to growth signaling, potentially influencing treatment sensitivity.
Molecular mechanism: Predicted ceRNA mechanism through miRNA binding, with enrichment of MAPK and Ras signaling and growth-control pathways.
Biological pathway or process:

MAPK (other); proliferation (other); drug resistance (other); radioresistance (other); ceRNA regulation (other); other pathway/process (other)

Detected method:
Q
Validation methods:

Back-Splice Junction PCR / divergent primers PCR; RT-qPCR; Bioinformatics Analysis

Clinical significance:

Potential radiation sensitivity biomarker and therapeutic target to improve TNBC treatment efficacy.

Description:

circFBXW7 is progressively induced after irradiation in TNBC cells. Predicted miRNA interactions and pathway enrichment suggest that it may connect DNA damage response to MAPK/Ras growth signaling and may affect radiation treatment sensitivity.

Confidence score:

0.329
