Figure 1 Expression and location of p62 detected by IHC. EnVision (A–C, E×200, D×100). A: p62 expression in cytoplasm of squamous cell carcinoma but not in the site of keratinization; B: p62 expression in cytoplasm of well-differentiated adenocarcinoma; C: p62 expression in cytoplasm of HCC; D: Distribution of p62 in cytoplasm of morphologically normal columnar epithelial cells adjacent to cancer foci; E: Negative control.
