Figure Legend Snippet: Hypoxia induces the expression of HIF-1α in NSCLC cells. HIF-1α elevates expression of EZH2 which in turn reduces expression of FBXL7, and inhibits the ubiquitination of PFKFB4 by FBXL7, resulting in upregulation of PFKFB4 protein expression. By this mechanism, NSCLC cell glycolysis and malignant phenotypes are accelerated while cell apoptosis was decelerated.
