Figure 7B indicated that the expression of MKI67 was significantly correlated with the tumor purity of 14 cancers and the degree of B-cell invasion of 23 cancers. MKI67 was also associated with CD4+ T cell invasion in 22 cancers, CD8+ T cell invasion in 19 cancers, DC invasion in 25 cancers, neutrophil invasion in 24 cancers, and macrophage invasion in 17 cancers. The gene discussed is CD4; the disease is neoplasm.
