Fig. 2. miRNA-874 expression was inversely associated with DOR expression in HCC tissues, and high miR-874 expression predicted longer RFS and OS.

a The relative expression levels of miR-874 were assessed via qRT-PCR in 120 paired HCC and tumor-adjacent tissues. b Analysis of miR-874 expression in HCC tissues and tumor-adjacent tissues by ISH. c, d Kaplan–Meier analysis revealed five-year OS rates of 22.05 and 38.70% and five-year RFS rates of 11.77 and 31.34% in the low and high miR-874 expression groups, respectively, suggesting that the OS and RFS rates of the low miR-874 expression group were higher than those of the high miR-874 expression group (p < 0.01). e Analysis of DOR expression in HCC tissues and tumor-adjacent tissues by IH. The DOR was overexpressed in cytoplasm of colon cancer tissues but nearly absent from paired tumor-adjacent tissues. f Expression of miR-874 was inversely correlated with the mRNA level of the DOR (r = −0.467, p < 0.01, Spearman’s correlation analysis). Data are shown as the mean ± SD of three replicates (*p < 0.05)
