| Research Abstract |
In this study, we demonstrated that HOXB9, a member of homeobox genes, expression promoted tumor neovascularization and metastasis in in vitro and in vivo assay. These findings imply that overexpression of HOXB9 contributes to tumor progression through activation of signaling pathways that alter both tumor-specific cell fates like epithelial-mesenchymal transition (EMT) and tumor-stromal microenvironment. Moreover, Clinical outcomes were significantly different between the patients with HOXB9 positive and negative, suggesting HOXB9 might be a significant prognostic factor for clinical outcomes in breast cancer patient.
