XPO4 and hepatocellular carcinoma: The results in Figure 6 showed that higher mRNA expression levels of XPO1 (P=0.047), CSE1L (P=0.0048), XPO5 (P=1.8e-7) and XPO6 (P=0.026) were associated with short DFS in HCC patients, but higher mRNA expression levels of XPOT (P=0.26), XPO4 (P=0.51) and XPO7 (P=0.052, borderline significance) were irrelevant to DFS.
