a, HIF-2α and HIF-1α
immunohistochemistry. 786-O cells, which express high levels of
HIF-2α, shown as controls. Scale bars, 100 µm.
b, Western blot analyses showing heterogeneity within
tumors but with overall similar results (compare to Fig. 3c). Green, sensitive; Red, resistant. Asterisks,
underloaded samples. c, Heatmap from RNA-seq analysis showing
differentially expressed genes in sensitive (S) versus resistant (R)
tumourgrafts based on uniform cutoff (see Extended Data Table 3). See Supplementary Fig. 1 for gel source
data.
