The goal of this study was to explore the molecular mechanism of hypoxia inducible factor-1 alpha (HIF-1 alpha) action on migration and invasion of esophageal carcinoma cells. We used cobalt chloride (CoCl(2) ) to mimic tumor hypoxic microenvironment and analyzed the expressions of E-cadherin, matrix metalloproteinase-2 (MMP-2), and HIF-1 alpha in(More)
