Although four mediators (IL-6, IL-27, TNF-α, and VEGF) significantly over-expressed, IL-6 presented the strongest correlation in HCC-total versus CH-total or HG groups (HCC-total versus CH-total: P < 0.001; HCC-total versus HG: P < 0.001). This evidence concerns the gene VEGFA and cyclic hematopoiesis.
