HIF1A and neoplasm: Our results show that TET could significantly inhibit endothelial cell (EC) proliferation, adhesion, migration, invasion, and tube formation by targeting angiogenic factors, namely vascular endothelial growth factor (VEGF) and hypoxia-Inducible factor-1α (HIF-1α), as well as adhesion factors, such as integrin β5, endothelial cell specific molecule-1 (ESM-1), and intercellular adhesion molecule-1 (ICAM-1), and by interfering with the ERK pathway, leading to the suppression of tumor metastasis and tumor angiogenesis.
