The correlation analysis showed that mTORC1 activation was significantly correlated with enhanced glutaminase activity (Figure 7C) as well as lower GCN5L1 protein levels (Figure 7D) but not with c‐Myc expression (Figure 7E) or transcripts of SLC1A5 and SLC7A6 (Figure S5A,B) in HCC specimens. Here, GLS is linked to hepatocellular carcinoma.
