Backgroud:
Esophageal squmaous cell carcinoma (ESCC) and gastric cancer are commonly seen in China, with high mortality and fatality in the world. As a key regulator to adapt hypoxia environment, hypoxia-inducible factor-1 alpha (HIF-1α) is involved in ESCC and gastric cancer. HIF-1αplays an important role in tumor angiogenesis, invasion and metastasis. Vasculogenic mimicry (VM) is a capillary structure formed by aggressive tumor cells instead of endothelial cells. It is a novel pathway to gen...
