ARF is the second most commonly inactivated tumor suppressor behind p53. It has been implicated in the control of cell proliferation, cell senescence, and tumor suppression. However, the detailed mechanism underlying the transcriptional control of ARF remains largely unknown. Here we report RUVBL2 as a novel transcriptional repressor of ARF. Ectopic(More)
Although camptothecin (CPT) has been reported to induce apoptosis in various cancer cells, the molecular details of this regulation remain largely unknown. In this study, we demonstrate that BH3-only protein Noxa is upregulated during CPT-induced apoptosis, which is independent of p53. In addition, we show that phosphatidylinositol 3-kinase (PI3K)/Akt(More)
