BIRC8 and neoplasm: To comprehend the functions of the IAP family members in HCC, we employed TIMER to investigate the molecular characteristics of tumor-immune interactions. Figure 4 illustrates that except of BIRC8, the transcriptional expression of the remaining IAPs exhibited a positive correlation with the expression of B cells, CD8+ T cells, CD4+ T cells, neutrophils, macrophages, and dendritic cells (DCs) (R> 0.1, P < 0.05).
