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

Figure 4

HIF-1α contributes to the tumorigenic function of IDH1 mutation in JJ012 cells. (a) Colony formation assay with JJ012 parental and IDH1mut KO cells under hypoxic (1% O2) and normoxic (21% O2) conditions. 5 × 103 cells per well were seeded in 6-well plates and incubated for 10–14 days. Graphs compare effects of hypoxia and normoxia on the number of colonies in the parental, KO1, and KO2 groups. Data indicate of triplicate cultures and are representative of 3 independent experiments. . (b) Immunoblot shows HIF-1α levels in JJ012 parental and IDH1mut KO cells under normoxia (N) and hypoxia (H) conditions.
