Based on our recognition for the importance of tumor microenvironment(TM), TM induces acquisition of malignant phenotype such as epithelial-mesenchymal transition (EMT), resulting in metastasis into lymph nodes. In this study, persistent tissue hypoxia might be involved in tumor tissue in an in vivo orthotopic intrapulmonary implantation model. Persistent hypoxia also induced the stabilized HIF1α expression in lung cancer cells. Transduction of HIF1α into lung cancers with the Doxycycline inducible gene expression system caused de novo VEGF-A expression. Taken together with the evidence of increasing VEGF receptor expression lymphatic endothelial cells in sentinel lymph nodes, hypoxia as TM in lung cancers might be a therapeutic target for the metastasis into lymph nodes and lymphangiogenesis.

基于我们对肿瘤微环境（TM）重要性的认识，TM诱导了诸如上皮 - 间质转变（EMT）等恶性表型的获取，从而导致转移到淋巴结中。在这项研究中，在体内原位肺内植入模型中，持续的组织缺氧可能与肿瘤组织有关。持续性缺氧还诱导了肺癌细胞中稳定的HIF1α表达。将HIF1α转导到肺癌中，强力霉素诱导基因表达系统导致从头vegf-a表达。与哨兵淋巴结中VEGF受体表达的淋巴内皮细胞增加的证据一起，肺癌中的TM缺氧可能是转移到淋巴结和淋巴管生成的治疗靶点。
