To explore whether GPX3, DIO1, and LRRC19 still correlate when including the normal tissue samples, we performed correlation analysis in the datasets of “523 TCGA tumor cases + 72 TCGA normal cases” (Figure 4c) and “523 TCGA tumor cases + 72 TCGA normal cases + 28 GTEx Kidney-Cortex cases” (Figure 4d). Here, GPX3 is linked to neoplasm.
