NEDD9 and lung adenocarcinoma: In our study, we immunohistochemically compared NEDD9 expression and localization in 60 FFPE lung adenocarcinoma tissues and analyzed NEDD9 mRNA and protein levels in three invasive lung adenocarcinoma cell lines, and also investigated the expression and clinical significance of NEDD9 in 60 surgically resected stage I through IV lung adenocarcinomas with known clinicopathological features.
