To evaluate the potential relationship between DUSP2 expression and tumor immunity in PCa, GSEA was conducted using GSE60329, and the results showed that T-cell receptor signaling pathway, adaptive immune response, immune receptor activity, and immune response regulating cell surface receptor signaling pathway were enriched in the low DUSP2 expression group (Figure 7A). The gene discussed is DUSP2; the disease is posterior cortical atrophy.
