Figure 1. Expressions of TC1, β-catenin, and DNMT1 in representative lung cancer cases.
In a lung squamous cell carcinoma case, TC1 was highly expressed in the cytoplasm. Some cancer cells also showed nuclear staining of TC1. Expression of β-catenin and DNMT1 were both positive in the same case. In another adenocarcinoma case, TC1 was highly expressed in the cytoplasm. Some cancer cells also showed nuclear staining of TC1. Expression of β-catenin and DNMT1 were both positive in the same case (Original magnification, 200×; streptavidin-peroxidase immunohistochemistry method).
