Fig. 1: FUT8 is highly expressed in ccRCC and associated with poor prognosis.

A FUT8 expression in ccRCC and normal kidney tissues from the TCGA-KIRC dataset. B Kaplan–Meier overall survival analysis comparing patients with low versus high FUT8 expression. C, D FUT8 protein levels in ccRCC tissues (T) and matched adjacent normal tissues (N) assessed by Western blotting (n = 30 patient pairs). E Representative immunohistochemistry images of FUT8 in ccRCC and normal tissues (Scale bar: 100 µm). Data are presented as mean ± SD. Statistical significance was evaluated using a paired t test. ns, P > 0.05; *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001.
