| Expression pattern: |
UP |
| Associated gene: |
IGF2BP2, STING, FTO |
| Associated microRNA: |
- |
| Biological function: |
promotes CRC cell proliferation, migration and invasion; facilitates tumor growth; promotes M2 macrophage polarization |
| Molecular mechanism: |
circASPH interacts with IGF2BP2 to stabilize IGF2BP2 protein, thereby enhancing IGF2BP2-dependent stabilization of m6A-modified STING mRNA and promoting exosomal STING-mediated M2 macrophage polarization |
| Biological pathway or process: |
proliferation (promotes); migration (promotes); invasion (promotes); apoptosis (inhibits); macrophage polarization (promotes); immune regulation (promotes); mRNA stability (promotes); ubiquitination (inhibits); other pathway/process (promotes) |

| Clinical significance: |
circASPH may serve as a promising therapeutic target for CRC treatment |
| Description: |
circASPH is upregulated in colorectal cancer and acts as an oncogenic circRNA. It promotes CRC cell proliferation, migration, invasion and tumor growth, while also enhancing M2 macrophage polarization through an IGF2BP2-dependent stabilization of m6A-modified STING mRNA and exosomal STING transfer. |
