GSTO2 and gangliocytoma: We identified 10 different genes that may be associated with the prolongevity effect of GNC (Figure 4); compared with the control group, GNC downregulated the expressions of R04A9.7, skr-9, vang-1, skr-7, skr-8, cyd-1, and fat-7 genes, while it upregulated the expressions of gsto-2, kgb-2, and skr-5 genes (p < 0.05).
