In addition, the relation of eIF5A expression and immune cell infiltration was explored through TIMER database, and the results showed that eIF5A expression has no significant correlation with the infiltration of purity cells, B cells, CD8+ T cells, CD4+ T cells, macrophages, neutrophils, and dendritic cells in ACC (Supplementary Figure 1). The gene discussed is CD4; the disease is adrenal cortex carcinoma.
