HMOX1 and cancer: Figure 2 shows that Ocoxin deregulated three genes in common in all the four cancers: CHAC1, HMOX1 and NQO1. Moreover, it was remarkable that PAAD and TNBC shared 67 genes (14%) involved in metabolic pathways, while the rest of paired comparisons shared less than 20 except for PRAD and TNBC, that shared 27 genes (6%). Thus, a more in-depth analysis was performed about those 67 metabolic genes by using the STRING software considering all the genes gathered in the “hsa01100: metabolic pathway” KEGG identifier. The network present in Figure 3 showed that all the genes were linked between them.
