Model of CASC9 interaction with CBP and the signaling pathways involved in pro-metastatic function. a In the nucleus, CASC9 recruits CBP and modulates H3K27ac levels at the LAMC2 promoter, thereby facilitating gene transcription. b In the cytoplasm, LAMC2 is exported to the extracellular matrix and interacts with ITGB4 to activate FAK-PI3K/Akt signaling pathways, thereby promoting ESCC metastasis
