As shown in Fig.7, after liver cancer treatment, the TGF-β1 and IL-10 concentrations were positively correlated with the percentage of CD4+CD25+ CD127lowTregs in patients with HCC respectively (r = 0.543, P = 0.013; r = 0.789, P=0.000). This evidence concerns the gene TGFB1 and hepatocellular carcinoma.
