Figure 8. Correlations between expressions of 26S proteasome delta subunit, non-ATPase (PSMD) family members and immune infiltration profiles of breast cancer via the TIMER database. The figure shows correlations between each abnormally expressed gene of the PSMD family and levels of several tumor-infiltrating immune cell markers, such as B cells, cluster of differentiation 8-positive (CD8+) T cells, CD4+ T cells, macrophages, neutrophils, and dendritic cells.
