| Expression pattern: |
UP |
| Associated gene: |
ZEB1, ZEB2, ETS1, AGO2 |
| Associated microRNA: |
miR-200c-3p |
| Biological function: |
promotes proliferation, migration, invasion and metastasis of breast cancer cells |
| Molecular mechanism: |
acts as a miRNA sponge for miR-200c-3p, leading to up-regulation of miR-200c-3p target genes (ZEB1, ZEB2, ETS1) |
| Biological pathway or process: |
proliferation (promotes); migration (promotes); invasion (promotes); metastasis (promotes); ceRNA regulation (promotes) |

| Clinical significance: |
Higher expression of hsa_circ_001783 associated with higher tumor burden and poorer prognosis; an independent factor for predicting prognosis (DFS). |
| Description: |
hsa_circ_001783 is up-regulated in breast cancer (particularly TNBC) and mainly localized in the cytoplasm. It promotes proliferation and metastatic traits by sponging miR-200c-3p, thereby derepressing miR-200c-3p targets such as ZEB1/2 and ETS1. High hsa_circ_001783 expression correlates with heavier tumor burden and poorer disease-free survival, supporting its prognostic potential. |
