Using gene set variation analysis (GSVA) of the core enriched genes from the PPP ( XYLB , RPE , and TALDO1 ) and arginine metabolism ( CPS1 , NAGS , ASS1 , CKM , AOC1 , and GATM ), together with the rate-limiting enzymes of the PPP ( G6PD and PRPS1 ), we confirmed that the PPP was upregulated (Figure 5, C and D) and that arginine metabolism was downregulated (Figure 5, E and F) in CR hi tumors compared with CR lo tumors in both the lung and liver tumors (Supplemental Tables 3 and 4)
