To assess Aurora kinases expression in HCC tissues, we examined the expression of Aurora A and B protein in 24 cases of HCC matched with adjacent tissues by Western blot, and found that the expression of Aurora A and B were both significantly higher than those of corresponding adjacent tissues (Aurora A P = 0.0001, Aurora B P = 0.003) (Figure 1A–1B). Here, AURKB is linked to hepatocellular carcinoma.
