Disabled-2 expression is reduced in many cancers, suggesting that it is a potential tumor suppressor protein. To elucidate the role of Disabled-2 in lung cancer, we examined the expression of Disabled-2, the Disabled-2-binding protein Axin, and DNA methyltransferase-1 in lung cancer tissues and corresponding normal lung tissues using immunohistochemistry and Western blots. We also determined the subcellular localization of Axin and Disabled-2 in A549 cells using confocal immunofluorescence. Disabled-2 expression was significantly reduced in lung cancers and was colocalized and coexpressed with Axin (correlation coefficient = 0.321, P < .001 for cytoplasmic expression; correlation coefficient = 0.393, P < .001 for nuclear expression). Reduced nuclear Disabled-2 expression was correlated with the differentiation (P = .048) and TNM stage (P = .048) of the tumor. The cytoplasmic expression of Axin was also correlated with differentiation (P = .042), whereas the nuclear expression of Axin was correlated with both histologic type (P = .001) and TNM stage (P < .001) of lung cancers. Expression of DNA methyltransferase-1 was negatively correlated with the cytoplasmic expression of Axin (correlation coefficient = -0.244, P = .012) but positively correlated with the histologic type (P = .004), differentiation (P = .036), TNM stage (P = .044), and lymphatic metastasis (P = .011). Expressions of Disabled-2 and Axin were concurrently reduced and correlated with the malignant phenotype of lung cancers. Enhanced expression of DNA methyltransferase-1 correlated with the reduced expression of Axin and could be a marker for lung cancer development and progression.
