As depicted in Figure 4A, increased mRNA expression of RECK in HCC was significantly associated with the infiltration levels of all the 6 immune cells including B cell, CD4+T cell, CD8+T cell, Macrophage cell, Neutrophil cell and DC cell, indicating that RECK mRNA expression is associated the recruitment of more immune cells in HCC. The gene discussed is CD4; the disease is hepatocellular carcinoma.
