Molecular mechanism: |
CircPICALM colocalized with hsa-miR-1265 and acted as a sponge for this miRNA, and the pro-invasion effect of hsa-miR-1265 was abolished by circPICALM overexpression. STEAP4, a target of hsa-miR-1265, suppressed metastasis, it bound to FAK to prevent autophosphorylation at Y397 and influenced EMT in BC cells. |
