Aberrant receptor kinase signalling and tumour neovascularization are hallmarks
of medulloblastoma development and are both considered valuable therapeutic
targets. In addition to VEGFR1/2, expression of PDGFR ?/? in particular has been
documented as characteristic of metastatic disease correlating with poor
prognosis. Therefore, we have been suggested that the clinically approved
multi-kinase angiogenesis inhibitor Axitinib, which specifically targets these
kinases, might constitute a promising option for medulloblastoma treatment.
Indeed, our results delineate anti-neoplastic activity of Axitinib in
medulloblastoma cell lines modelling the most aggressive c-myc-amplified
Non-WNT/Non-SHH and SHH-TP53-mutated tumours. Exposure of medulloblastoma cell
lines to Axitinib results in marked inhibition of proliferation and profound
induction of cell death. The differential efficacy of Axitinib is in line with
target expression of medulloblastoma cells identifying VEGFR 1/2, PDGFR ?/? and
c-kit as potential markers for drug application. The high specificity of Axitinib
and the consequential low impact on the haematopoietic and immune system render
this drug ideal multi-modal treatment approaches. In this context, we demonstrate
that the clinically available PI3K inhibitor GDC-0941 enhances the
anti-neoplastic efficacy of Axitinib against c-myc-amplified medulloblastoma. Our
findings provide a rational to further evaluate Axitinib alone and in combination
with other therapeutic agents for the treatment of most aggressive
medulloblastoma subtypes.
