描述 | SYP-5 acts as an inhibitor of the hypoxia-induced increase in HIF-1 levels. It effectively suppresses both HIF-1 and the subsequent gene expression in Hep3B and Bcap37 cells. SYP-5 also hinders the migration and invasion of tumor cells, along with tumor angiogenesis, by targeting the PI3K/AKT and MAPK/ERK pathways that are dependent on HIF-1. The HIF-1 target proteins, VEGF and MMP-2, are downregulated by SYP-5, which significantly curtails the hypoxia-driven overexpression of these proteins in both cell lines. In vitro, SYP-5 inhibits angiogenesis as observed in tube formation assays, induced by both hypoxia and VEGF. Moreover, SYP-5 slows down the migration and invasion of Hep3B and Bcap37 cells caused by hypoxia and FBS. Notably, SYP-5 selectively blocks the hypoxia-induced luciferase expression in U251-HRE cells but not in U251-pGL3[1]. |
