Figure 1From: Aberrant nuclear localization of β-catenin without genetic alterations in β-catenin or Axin genes in esophageal cancerImmunohistochemical staining of β-catenin in normal and cancer tissues of the esophagus. In this cancer tissues, β-catenin was expressed in the nuclei, and was hardly detectable at the plasma membrane (a). In normal esophageal epithelium, β-catenin was expressed at the cell membrane (b).Back to article page
