Hypoxia Imaging and Biological Evaluation of the Radiosensitizing Effect of Oleanolic Acid

Figure 5

Immunohistochemical staining of multiple tumor biological markers after treatment. HIF-1α, Glut-1, Ki67, P53, and MVD expressions in tumors were downregulated in the IR group and the OA combined with IR group. HIF-1α = hypoxia-inducible factor, Glut-1 = glucose transporter, Ki67 = proliferation antigen, P53 = tumor suppressor, and MVD = microvessel density.
