In addition to Myc, there were a number of other established oncogenes that had SE specifically in SCC-SCs but not in HF-SCs, including Fos, Jun, Src, and Tgfa. Also on this list, there were cytokine genes Cxcl1 and Cxcl2, as well as genes associated with cancer metabolism such as Slc2a1 and Gsr (Figure 1G). This evidence concerns the gene SLC2A1 and hydrops fetalis.
