Integrative Analysis Reveals the Landscape of Hypoxia-Inducible Factor (HIF) Family Genes in Pan-Cancer

Figure 2

Copy number variations contribute to abnormal expression of hypoxia-inducible factors. (a) Copy number variations associate with HIF gene expression in cancers. (b) Copy number variation of the HIF gene includes heterozygous amplification and homozygous amplification. CNV: copy number variation, Hete: heterozygous, Homo: homozygous.
