As shown in Fig. 6, there were remarkable associations between the differential expression levels of SAT1 mRNA and age (P = 0.015), tumor grade (P = 4.881e-06), IDH (P = 6.11e-03), radiation therapy (P = 1.738e-04), and histology type (P = 5.288e-08). The gene discussed is IDH2; the disease is neoplasm.
