molecular markers for survival and sensitivity to therapy is therefore important both for prognosis as well as elucidating mechanisms associated with tumorigenesis. A recent study has identified a novel protein, RRP1B, as being associated with reduced proliferation and metastasis and improved survival in breast cancer; however, the mechanism remains unclear. In this study, we identify RRP1B in a screen for specific targets of the DNA damage induced pro-apoptotic transcription factor ...
