title: Vascular and perivascular GD3 expression in human glioma.
abstract: A major hallmark of gliomas is their intense neovascularisation. Ganglioside GD3, is one of the major gangliosides which has been implicated in tumour angiogenesis. Recently we reported that GD3 was a potent stimulator of vascular endothelial growth factor release in human glioma cell lines. In the present study we were able to detect GD3-immunoreactivity in 10 out of 10 cases of glioblastoma multiforme and 7 out of 10 cases of anaplastic astrocytoma while low grade tumours were negative. Interestingly, GD3 was intensively expressed in hypervascularised areas of high grade gliomas. These data support the involvement of this ganglioside in brain tumour angiogenesis.
