(C,D) GSEA pathway enrichment analyses of HGD or GSTZ1 signature in patients with RCC from the TCGA datasets. (E) The overlapping analysis for related genes of amino acid metabolism in RCC patients. (F,G) The core-enriched signaling pathways in high and low GOT1 or GOT2 groups. NES, normalized enrichment score. (H) The mRNA and protein expression levels of GOT1 and GOT2 between tumor and normal tissues in patients with KIRC in TGCA database. (I) The expression correlation between HGD/GSTZ1 and GOT1/GOT2. *** p < 0.001.
