| Expression pattern: |
UP |
| Associated gene: |
ACVR1C/ALK7, FZD3, IL6ST/GP130, SKIL/SNON, SMAD2, WNT5A |
| Associated microRNA: |
miR-140-3p, miR-224, miR-548c-3p, miR-579 |
| Biological function: |
Modulates CSC stemness properties in CRC spheroid cells by sponging tumor suppressor miRNAs, leading to increased expression of stemness-related mRNA targets. |
| Molecular mechanism: |
ceRNA mechanism (circRNA sponging of miRNAs) regulating mRNA targets involved in pluripotency-related signaling pathways (GP130/Stat, Activin/Nodal, TGF-beta/SMAD, Wnt/beta-catenin). |
| Biological pathway or process: |
stemness (promotes); ceRNA regulation (promotes); Wnt/beta-catenin (promotes); TGF-beta/SMAD (promotes); JAK/STAT (promotes) |

| Validation methods: |
circRNA-seq; RNase R Treatment; divergent primers PCR; RT-qPCR; Bioinformatics Analysis; Luciferase Reporter Assay |
| Clinical significance: |
May be included in a circRNA-miRNA-mRNA panel as a precision biomarker for diagnosis and prognosis of colorectal cancer progression. |
| Description: |
hsa_circ_0066631 is up-regulated in CSC-enriched CRC spheroid cells and acts as a miRNA sponge to suppress core miRNAs, thereby derepressing stemness-related mRNA targets involved in pluripotency-associated signaling pathways (e.g., GP130/Stat, TGF-beta/SMAD, Wnt/beta-catenin) and promoting stemness-associated phenotypes. |
