CDC25B is over-expressed in hepatocellular carcinoma compared to non-tumor liver. A) Significant over-expression of CDC25B transcript in hepatocellular carcinoma tumor compared to adjacent non-tumor liver in 24 pairs of tissue specimens (P < 0.001). The amount of CDC25B was normalized with 18s rRNA to control for RNA amount variation. B) Representative immunostaining of CDC25B in hepatocellular carcinoma tissue and adjacent non-tumor liver tissue. Photos were taken at ×20 magnification.
