Analysis of immune cell infiltration. KRT7 (A), CD44 (B), CXCL12 (C), TGFBR2 (D) and HIF1A (E) expression correlations with tumor purity and infiltrating levels of B cells, CD8 + T cells, CD4 + T cells, macrophages, neutrophils, and dendritic cells in TIMER database. The scatter plots displayed the purity-adjusted spearman’s rho value and statistical significance.
