KYNU and glioma: Once we showed KYNU overexpression in some cancers using the TCGA-GTEx data, especially in GBM and LGG, the next step was to evaluate KYNU expression in glioma using both TCGA and CGGA data (Figure 3A,B, respectively) to determine if these alterations in the expression of KYNU were also present in another population group (different race).
