The results showed a negative correlation between the levels of MND1 expression with the tumor purity of KIRC samples and significant correlations with different types of immune cells, including B cell (r=0.136; p=3.47e-03), CD8+T cell (r=0.123; p=1.03e-02), Macrophage (r=0.098; p=3.78e-02), Neutrophil (r=0.141; p=2.43e-03), and Dendritic cell (r=0.166; p=3.76e-04) (Figure 8A). The gene discussed is CD8A; the disease is neoplasm.
