NCOA3 and lung adenocarcinoma: Employing the previously described criterion (normal expression and overexpression of AIB1 were identified when at least 10% and more than 10%, respectively, of tumor cell nuclei were positively stained), overexpression of AIB1 was observed in 41.3%, 60.6%, 47.4%, and 80% of samples in the N0, N+, M0, and M1 stages of lung adenocarcinoma, respectively (Table 1).
