PODXL and neoplasm: This association between PODO447 glycoepitope expression and low immune infiltrates is not directly caused by an increase in overall PODXL core protein expression in the PODO447 high tumors, as we find no clear associations between PODXL expression (i.e. PODO83 immunoreactivity) and immune infiltration in the stroma or tumor areas (Supplementary Figure 1B).
