SLC7A5 and colorectal carcinoma: Figure 1A shows one co-downregulated gene (MT1G), and Figure 1B shows two co-upregulated genes (SLC7A5 and TRIB3) (Figures 1A,B). Then, the PrognoScan database (Mizuno et al., 2009) and DRUGSURV database (Amelio et al., 2014) were used to explore the prognostic values of these ferroptosis-related genes in CRC patients from GSE17536 and GSE17538. As shown in Figures 2A–F, a high level of MT1G indicated good prognosis in patients with CRC. However, SLC7A5 and TRIB3 have no significant effects on the prognostic values.
