With respect to liver cancer, high expression of FNDC1 (Fig. 5a and b), FNDC3A (Fig. 5c and d), FNDC5 (Fig. 5e and f), and FNDC7 (Fig. 5h) was correlated with better prognosis, but increased expression of FNDC6 (Fig. 5g) and FNDC8 (Fig. 5i) was correlated with poor OS and PFS, respectively. This evidence concerns the gene FNDC7 and liver cancer.
