| Outline of Final Research Achievements |
The transcription factor E2F is the main target of the tumor suppressor RB. E2F plays central role in cell growth upon growth stimulation. E2F also plays important role in tumor suppression by inducing apoptosis or cellular senescence upon dysfuncrion of RB. We analyzed molecular mehcanism of discrimination of target genes involved in cell growth and tumor suppression, and identified involvement of phosphorylation status of E2F1. We searched new target genes specifically activatived by dysfunction of RB by using DNA microarray, and identified 9 novel targets including BIM. We searched new interacting proteins of E2F1 by using co-immunoprecipitation coupled with mass spectrometry and yeast two-hybrid system, and identified 52 candidates including DDX5.
