Immunohistochemical analysis of the hepatocellular carcinoma tissue microarray. (A) Representative examples of scoring performed for HDAC1 staining on tumor tissue. A tissue section with negative staining was given a score of 0 while scores 1–3 indicate the intensity of the nuclear staining of the hepatocytes. (B) Representative examples of scoring performed for HDAC2 staining on tumor tissue. A tissue section with negative staining was given a score of 0 while scores 1–3 indicate the intensity of nuclear staining of the hepatocytes. Scale bar, 50 µm. HDAC, histone deacetylase.
