Interestingly, we further found that high expression of SLC7A11 were significantly associated with shortened OS and disease-free survival of KIRP, LIHC, and MESO (mesothelioma), and high expression of GPX4 was significantly correlated with shortened OS and disease-free survival of STAD (Figures 4A–H). This evidence concerns the gene SLC7A11 and mesothelioma.
