Protein expression patterns of SIRT3 in HCC tissues by IHC. Zhiyi ZhangChris LiuLili CaiMuyan PanYinghua FuJia CaoYun YunJingping 2012 <p>The immunoreactivities were primarily observed in cytoplasm within tumor and normal liver cells. The micrographs showed negative (<b>A</b>), low (<b>C</b>), and high (<b>E</b>) expression of SIRT3 in HCC tissues. The relevant expressions of SIRT3 in corresponding adjacent normal liver tissues of cases in <b>A</b>, <b>C</b> and <b>E</b> were shown in <b>B</b>, <b>D</b> and <b>F</b>, respectively.
