Figure 7. Investigation of the association between PTPN11 expression and immune infiltration of endothelial cells. (A) Using the EPIC, MCPCOUNTEER, and XCELL algorithms, a link was found between PTPN11 expression and the amount of endothelial cell infiltration. (B) The relationship between PTPN11 expression and endothelial cell infiltration levels in COAD, HNSC, LUAD, LUSC, and PAAD.
