In this study, as shown in Figure 7, key genes associated with cancer cells metabolism (Pfkfb3, Fgfbp1, Gnas, Pfkfb4, Ctnnb1, and Tsta3), glucose metabolism (Pgls and Hkdc1), lipid synthesis (Agpat4, Pklr, and Ctnnb1), lipid hydrolysis (Enpp4), lipid transport (Agap2), fatty acid metabolism (Mcpt1), amino acid metabolism (Arg2 and Glud1), cell differentiation (Tacc1), and tissue repairment (Fgfbp1) were remarkably downregulated in EgPSC-infected mice. This evidence concerns the gene GNAS and cancer.
