Markers of hypoxia are associated with all orthotopically transplanted models of MB. Representative IHC microscopy of HIF1α and CAIX in MCre:Ptch1 (A, E), SHH PDOX (B, F), Gp3 PDOX (C, G), and ortho-MCre:Ptch1 (D, H). All images were acquired at ×20 total magnification. Scale bars: 200 μm. Hypoxia-inducible factor 1 α binding sites within the promoter sequence of PLVAP (I). CAIX, carbonic anhydrase IX; HIF1α, hypoxia-inducible factor 1 subunit α; IHC, immunohistochemistry; MB, medulloblastoma; PDOX, patient-derived orthotopic xenograft; SHH, Sonic Hedgehog.
