Figure 4. Associations of TCOF1 expression with tumor purity and immune infiltration. (A) TCOF1 expression was positively correlated with tumor purity in BRCA-Luminal, HNSC, LUSC, pancreatic adenocarcinoma (PAAD), SARC, and SKCM based on TCGA data. (B–D) Correlation between TCOF1 expression level and infiltration levels of (B) CAFs, (C) MDSCs, and (D) HSCs across all types of cancer in TCGA.
