Noticeably, opposite correlations of B-cell infiltration with KPNA2 expression in HCC tumors (R = 0.289, p < 0.01) and the normal liver tissues (R = −0.226, p < 0.01) were also obvious here (Figure 1B), consistent with the results in the TCGA-HCC dataset, indicating the specificity of the positive correlation between KPNA2 expression and B-cell infiltration in the HCC tumors in contrast to the normal controls. This evidence concerns the gene KPNA2 and hepatocellular carcinoma.
