According to the expression of eleven genes (CHAC1, NQO1, SQLE, SLC1A5, GSS, LPCAT3, GPX4, AIFM2, ABCC1, ACSF2, FDFT1), tumor samples were classified into two clusters differing in prognosis and tumor microenvironment-infiltrating immune cells [204]. This evidence concerns the gene CHAC1 and neoplasm.
