To assess the relationship of TIPE2 expression and lung cancer tissues, we detected the expression status of TIPE2 in common histological types of lung cancer tissues by immunohistochemistry, including 25 lung adenocarcinoma tissues, 20 lung squamous carcinoma tissues, 15 small cell lung cancer tissues and 30 adjacent non-tumor lung tissues. This evidence concerns the gene TIPE2 and lung adenocarcinoma.
