Fig. 7From: Sublethal dose of irradiation enhances invasion of malignant glioma cells through p53-MMP 2 pathway in U87MG mouse brain tumor modelImmunohistochemistry for MMP-2 expression and in situ zymography for gelatinolytic activity in brain tissues with either radiation exposure or not. Autofluorescence of mice in the in situ zymography experiment was minimized by NaBH4. a Hematoxylin-Eosin stain; b Immunohistochemistry for MMP-2; c, d In situ zymography, green: gelatinolytic activity, blue: nucleusBack to article page
