Aberrant expression of peroxiredoxin 1 and its clinical implications in liver cancer

Figure 3 Expression of peroxiredoxin 1 in human liver cancer specimens. A: Western blot analysis of tumor (C) and matching adjacent non-tumor liver tissues (N) of 29 patients. β-actin protein levels are shown as a loading control. The patients were coded from 1 to 29; B: Densitometric analysis of 29 hepatocellular carcinoma cases. The black and gray bars represent the relative band intensity of peroxiredoxin 1 (PRDX1) in non-tumor or tumor tissues, showing the ratio between 22 kDa, 50 kDa or total PRDX1 and β-actin. Each data point represents the mean ± SD derived from three independent experiments.
