Figure 5. The mRNA expression of KPNA4 in the UALCAN database. (A) The mRNA expression level of KPNA4 was significantly higher in cancer tissues than in normal tissues. (B) The expression level of KPNA4 in HCC patients was higher than that in healthy people and was not associated with gender. (C) Patients (age > 21 years old) commonly had higher gene expression than young healthy people. (D) The expression level of KPNA4 was not correlated with patient weight. The expression level of KPNA4 was positively correlated with tumor stage (E) and tumor grade (F) in HCC. * represents P < 0.05, ** represents P < 0.01, *** represents P < 0.001.
