Query: HOXB7 induces STAT3-mediated transformation and lung metastasis in an immortalized mammary gland NMuMG cells Genes from the homeobox family are often dysregulated in cancer. Particularly, homeobox B7 (HOXB7) amplification and overexpression correlate with poor prognosis in various cancers, such as gastric, pancreatic, and lung cancers. Moreover, HOXB7 is known to contribute to cancer progression by promoting epithelial to mesenchymal transition, drug resistance, and angiogenesis. In this study, we show that HOXB7 overexpression correlates with a poor prognosis in patients with breast cancer. Coamplification of HOXB7 with ERBB2 enhanced the expression of ERBB2 and the malignancy of HER2-positive breast cancer cells. Additionally, HOXB7 overexpression in an immortalized murine mammary gland epithelial cell line, NMuMG, induced cellular transformation through an activation of the JAK-STAT signaling pathway, which resulted in lung metastasis upon orthotropic transplantation in mice. These findings reveal that HOXB7 alone is sufficient to induce tumorigenesis and lung metastasis using HOXB7-expressing NMuMG cells.
