PLA2G7 and diffuse large B-cell lymphoma: To fully explore the association between PLA2G7 expression and immune cell infiltration in the TME, CIBERSORT [25], which can be used to analyze the proportions of 22 of tumor-infiltrating immune cell (TIIC) types based upon RNA-seq data, was used to compare TIIC profiles in PLA2G7-low and -high DLBCL patients from the TCGA cohort (Fig. 6A).
