摘要：

More effective treatments for metastatic lung cancer remain a pressing clinical need. In this study, we identified migration inducting gene-7 (MIG-7) protein as critical for COX-2/prostaglandin E2 (PGE2)- and Akt/GSK-3 beta-dependent tumor invasion/metastasis. COX-2/PGE2 activated EP4 to enhance Akt and GSK-3 beta phosphorylation and beta-catenin/T-cell factor/lymphoid enhancer factor signaling leading to MIG-7 upregulation. RNAi-mediated attenuation of MIG-7 blocked COX-2/PGE2-and Akt/GSK-3 beta-mediated migration/invasion effects. Furthermore, MIG-7 protein inhibited protein phosphatase 2A to sustain Akt/GSK-3 beta phosphorylation and cancer-cell migration/invasion. Cancer cells overexpressing MIG-7 exhibited increased expression of ZEB-1 and Twist in parallel with epithelial-mesenchymal transition, metastasis and cancer lethality. MIG-7 protein level positively correlated with advanced stages of human lung cancers. MIG-7 thus offers a theranostic target for cancer metastases arising from aberrant activation of the cellular COX-2/PGE2 and Akt/GSK-3 beta signaling pathways. Cancer Res; 73(1); 439-49.
