| Associated gene: |
CEA, CA19-9 |
| Associated microRNA: |
- |
| Biological function: |
Serves as a plasma diagnostic biomarker for CRC; decreased in CRC and precursor lesions; useful for early-stage CRC diagnosis and postoperative improvement prediction. |
| Molecular mechanism: |
Not specified; the study evaluated circulating plasma circRNA levels as diagnostic biomarkers. |
| Biological pathway or process: |
not specified |
| Detected method: |

| Validation methods: |
Back-Splice Junction PCR / divergent primers PCR; RNase R Treatment; Sanger Sequencing; RT-qPCR; Clinical Sample Validation; ROC Analysis |
| Clinical significance: |
circ-CCDC66 is part of a three-circRNA plasma panel for CRC diagnosis; individual AUC was 0.756 in all samples, and it was useful for early-stage CRC, CEA-negative CRC, and CA19-9-negative CRC. |
| Description: |
circ-CCDC66 was significantly decreased in plasma from CRC patients and was included in a three-circRNA diagnostic panel. It also showed diagnostic value for early-stage CRC, CEA-negative/CA19-9-negative CRC, precursor lesions, and postoperative improvement prediction. |
| Confidence score: |
