As showed in Figure 5A, SLC1A4 expression was significant associations with tumor purity (p = 6.54e-02), B cell (p = 1.75e-10), neutrophils (p = 8.96–10), macrophages (p = 1.15e-11), CD4+ T cells (p = 1.42e-06), CD8+ T cells (p = 5.49e-04) and dendritic cells (p = 6.25e-09) in HCC. The gene discussed is CD4; the disease is hepatocellular carcinoma.
