MTA3 and metastatic malignant neoplasm in the lymph nodes: The relative expression level of MTA3 mRNA was significantly higher in NSCLC samples (118 samples, 0.2494 ±0.10361) than that in non-neoplastic samples(118 corresponding samples, 0.1578 ± 0.07694) (P = 0.002), and in NSCLC samples with lymph node metastasis(49 samples, 0.2810 ± 0.08593) than that in NSCLC samples without lymph node metastasis (69 samples, 0.2270 ± 0.10969) (P = 0.003) (Table 1).
