Regulation of the PML tumor suppressor in drug-induced senescence of human normal and cancer cells by JAK/STAT-mediated signaling
1 Aug 2010
Abstract excerpt
The Promyelocytic leukemia protein (PML) tumor suppressor is upregulated in several forms of cellular senescence, however the mechanism of its induction is elusive. Here we show that genotoxic drugs that induce senescence, such as 5-bromo-2'deoxyuridine (BrdU), thymidine (TMD), distamycin A (DMA), aphidicolin (APH), etoposide (ET) and camptothecin (CPT) all evoke expansion of PML nuclear compartment and its...
