Abstract
Methionine aminopeptidases (MetAPs) have been pharmacologically linked to cell growth, angiogenesis, and tumor progression, which make it an attractive target for cancer therapy. We investigated MetAP2’s biological role in glioblastoma (GBM), an aggressive tumor characterized by massive neovascularization. We examined the effect of anti-MetAP2 RNA interference on proliferation and angiogenesis in GBM cell line. The biological effects of MetAP2 knockdown were assessed by comparing the proliferation, tumorigenecity, and angiogenesis of parental cells and MetAP2 knockdown cells. We generated MetAP2 knockdown cells using lentiviral short hairpin RNAs against MetAP2 in SNB19 GBM cells, which normally express high levels of MetAP2. MetAP2 knockdown cells were less proliferative and less tumorigenic when compared to the parental cells. MetAP2 knockdown decreased vascular endothelial growth factor (VEGF) secretion and expression at the mRNA and protein levels. Decreased VEGF expression in MetAP2 knockdown cells correlated very well with decreased vessel formation in a tube formation assay. We showed that VEGF suppression in MetAP2 knockdown cells was mediated by the von Hippel-Lindau protein. In in vivo animal studies using an intracranial SNB19 tumor model, MetAP2 knockdown also reduced the tumor growth rate and angiogenesis, which in turn prolonged the survival of mice in xenograft model. Our results show that MetAP2 regulates angiogenesis in GBM and identify MetAP2-specific substrates that may serve as candidates for clinical assay development.
