To explore the relationship between PXDN expression and immune cell function in the tumor microenvironment, we used TIMER, EPIC, MCPCOUNTER, CIBERSORT, CIBERSORT-ABS, QUANTISEQ, and XCELL algorithms to comprehensively analyze the relationship between PXDN expression and the degree of T-cell infiltration in the tumor microenvironment. Here, PXDN is linked to neoplasm.
