Regression of glioma tumor growth in F98 and U87 rat glioma models by the Nitrone OKN-007.

ABSTRACT:

Background

Glioblastoma multiforme, a World Health Organization grade IV glioma, has a poor prognosis in humans despite current treatment options. Here, we present magnetic resonance imaging (MRI) data regarding the regression of aggressive rat F98 gliomas and human U87 glioma xenografts after treatment with the nitrone compound OKN-007, a disulfonyl derivative of α-phenyl-tert-butyl nitrone.

Methods

MRI was used to assess tumor volumes in F98 and U87 gliomas, and bioluminescence imaging was used to measure tumor volumes in F98 gliomas encoded with the luciferase gene (F98(luc)). Immunohistochemistry was used to assess angiogenesis (vascular endothelial growth factor [VEGF] and microvessel density [MVD]), cell differentiation (carbonic anhydrase IX [CA-IX]), hypoxia (hypoxia
