MTA3 and non-small cell lung carcinoma: To explore the role of MTA3 in NSCLC, we analysed 118 cases of NSCLC patients retrospectively between 2001 and 2005, detected the expression of MTA3 mRNA and protein with real time RT-PCR and immunohistochemical methods, and explore the relationship between expression of MTA3 mRNA and protein and survival time.
