DMP1 deletion cooperates with oncogenic K-ras in lung cancer

Scientists have identified the transcription factor DMP1 as a pivotal tumor suppressor for both human and mouse lung cancers, especially in carcinomas that exhibit intact Arf-p53 pathways. The research, published by Cell Press in the October 2007 issue of Cancer Cell , may lead to development of ...
