Abstract:
:Glioma is one of the most common primary brain tumors in adults with a high mortality rate and relapse rate. Thus, finding better effective approaches to treat glioma has become very urgent. Astragaloside IV (AS-IV), the major active triterpenoid in Radix Astragali, has shown anti-tumorigenic properties in certain cancers. However, its role in glioma remains unclear. Here, we studied the effects of AS-IV on glioma in vitro and in vivo, and explored the underlying mechanisms. Our results revealed that AS-IV dose-dependently inhibited the proliferation of U251 cells in vitro and attenuated tumor growth in vivo. In addition, the migration and invasion ability of U251 cell has been suppressed in presence of AS-IV. The levels of proliferating cell nuclear antigen (PCNA), Ki67, matrix metallopeptidase (MMP) -2, MMP-9 and vascular endothelial growth factor (VEGF) were decreased significantly by the treatment of different concentrations AS-IV. Furthermore, AS-IV also significantly weakened the activation of Mitogen-activated protein kinase/Extracellular regulated protein kinase (MAPK/ERK) signaling pathway in vitro and in vivo. Taken together our study has identified a novel function of AS-IV and provided a molecular basis for AS-IV potential applications in the treatment of glioma and other cancers.
