In addition, we also found that the cancer with high ACSL4 expression was positively correlated with the infiltration level of MDSC, including COAD, LIHC and STAD, whereas the cancer with low ACSL4 expression was negatively correlated with the infiltration level of MDSC, including BRCA, KIRC, LUSC, GBM and SKCM. This evidence concerns the gene ACSL4 and cancer.
