Abstract

The malignancy of glioblastoma multiforme (GBM) is largely due to its local invasion and the presence of the tumor in the relatively restrained region in the brain. Hence, effective prevention of the cancer cell invasion is substantially critical for controlling the growth and deterioration of GBM. We have recently reported the role of ginsenoside Rh2 (GRh2) in suppressing the growth of GBM through EGFR/PI3k/Akt/mTor signaling pathways. Here, we further showed that GRh2 efficiently inhibited the cancer vascularization in vivo. In vitro, GRh2 dose-dependently inhibited the protein, but not messenger RNA (mRNA) of vascular endothelial growth factor A (VEGF-A) in GBM cells. We then examined the underlying mechanisms and found that GRh2 increased the levels of miR-497, which bound to 3′UTR of VEGF-A mRNA to inhibit its translation. Together, our data demonstrate a previously unappreciated role for GRh2 in inhibition of GBM-associated cancer vascularization, which may contribute to the effects of GRh2 on suppression of GBM cancer growth and invasion.
