IDH1 Mutation Induces HIF-1α and Confers Angiogenic Properties in Chondrosarcoma JJ012 Cells

Figure 2

Loss of IDH1mut suppresses HIF-1α in JJ012 cells and tumor tissues. (a) Immunoblots show HIF-1α expression in JJ012 parental and IDH1mut KO cells; immunohistochemical (IHC) images show cytoplasmic IDH1 (b) and nuclear HIF-1α (c) expression in parental and IDH1mut KO JJ012-derived xenografts. IHC staining was quantified with intensity scores as detailed in Materials and Methods. Scale bars are 50 μm. Data represent of values from four random fields. .
