DNMT3a expression pattern and its prognostic value in lung adenocarcinoma

Our results indicate that DNMT3a expression in lung adenocarcinoma is associated with the histologically non-invasive type and lepidic subtype, and a favorable prognosis. We also showed that DNMT3a expression is an independent prognostic marker in lung adenocarcinoma. Since lack of DNMT3a is thought to facilitate tumor progression, DNMT3a might be clinically applicable as an indicator of favorable prognosis.
