Biological function: Associated with CRC ceRNA subnetwork via hsa-miR-1296-5p and POLA1 (functional role not experimentally validated).
Molecular mechanism: Predicted ceRNA interaction: hsa_circ_0000520-hsa-miR-1296-5p-POLA1.
Biological pathway or process:

ceRNA regulation (other); immune regulation (other)
Detected method:
Q
M
Validation methods:

Microarray; RT-qPCR; Bioinformatics Analysis; Clinical Sample Validation
Clinical significance:

Potential diagnostic and therapeutic paradigm for CRC (no circRNA-specific clinical endpoint reported).
Description:

hsa_circ_0000520 is a co-upregulated RPPH1-derived circRNA in CRC, detected by qRT-PCR with higher expression in multiple CRC cell lines than NCM-460. It is included in the predicted ceRNA subnetwork via the hsa-miR-1296-5p-POLA1 axis.
Confidence score:

0.4032
