A: Correlation matrix among statistically over-represented and biologically-validated HIFα targets in TCGA colon or breast cancer data. Spearman (ρ) coefficients were encoded in a pseudo-color scale wherein flattening of ellipses denotes increasing |ρ| values; blank cells indicate non-significant correlation pairs after Bonferroni post hoc comparisons. Transcripts are annotated using official gene symbols.
