Figure 1

Expression of PTEN in colon cancer specimens. Immunohistochemistry was performed using a monoclonal anti-PTEN antibody (A, C) or negative control antibody (B) on a section sequential to that used in (A). (A) Strong PTEN expression in a representative moderately-differentiated adenocarcinoma specimen from colon cancer patients without associated liver metastasis (×100). (C) Expression of PTEN is not observed in a representative moderately-differentiated adenocarcinoma specimen from colon cancer patients with liver metastasis (×100). (D) Expression of PTEN is not observed in a specimen from metastatic liver tumor, in contrast, PTEN expression is observed in normal liver tissue (×100).
