IHC data from the HPA database provided robust support for the differential expression patterns of 9 hypoxia-related DEGs (BGN, CA12, MIF, MT1E, NEDD4L, PCK1, SELENBP1, SLC2A1, and TGFBI) in CRC patients, consistent with observations at both mRNA and protein levels (Figure 2). This evidence concerns the gene MIF and colorectal carcinoma.
