HGF and hepatocellular carcinoma: Figure 1(d) illustrates the PPI analysis results of 24 mARGs through the STRING website tool to reveal the interactions between mARGs, and Figure 1(e) illustrates the constructed network of coexpression relationships. We revealed genetic mutations in 24 mARGs in HCC (Figure 1(f)). Fifty-four of the 371 HCC samples (14.56%) showed mutations in mARG, with HGF being the most mutated gene among the 24 mARG, followed by EGF, SRC, and EFNB2. In addition, Figures 1(g) and 1(h) show the CNV alterations as well as the altered loci on the chromosomes of the 24 mARGs.
