SKA1 expression levels were significantly correlated with weight (Fig. 6A), age (Fig. 6B), T stage (Fig. 6C), N stage (Fig. 6D), M stage (Fig. 6E), tumor status (Fig. 6F), AFP levels (Fig. 6G), pathologic stages (Fig. 6H), histologic grade (Fig. 6I), OS (Fig. 6J), DSS (Fig. 6K), and PFI (Fig. 6L) of the HCC patients. This evidence concerns the gene AFP and hepatocellular carcinoma.
