In particular, in BRCA, LGG, HCC, PCPG, PRAD, rectum adenocarcinoma (READ), and thyroid cancer (THCA), RALA with elevated expression levels was significantly positively correlated with CD8+ T cell, Neutrophil, Myeloid dendritic cell, Macrophage, and B cell (Figure 4B), which were also validated in the TIMER database (Figure 4C). This evidence concerns the gene CD8A and hepatocellular carcinoma.
