The PML gene of acute promyelocytic leukaemia (APL) encodes a cell growth and tumour suppressor, however, the mechanisms by which PML suppresses tumorigenesis are poorly understood. We show here that Pml is required for Fas- and caspase-dependent DNA-damage-induced apoptosis. We also found that Pml is essential for induction of programmed cell death by Fas,(More)
The tumor-suppressive promyelocytic leukemia (PML) protein of acute promyelocytic leukemia (APL) has served as one of the defining components of a class of distinctive nuclear bodies (NBs). PML is delocalized from NBs in APL cells and is degraded in cells infected by several viruses. In these cells, NBs are disrupted, leading to the aberrant localization of(More)
The PML gene encodes a tumour suppressor protein associated with a distinct subnuclear domain, the nuclear body. Various functions have been attributed to the PML nuclear body, but its main biochemical role is still unclear. Recent findings indicate that PML is essential for the proper formation of the nuclear body and can act as a transcriptional(More)
The gaseous plant hormone ethylene regulates a multitude of growth and developmental processes. How the numerous growth control pathways are coordinated by the ethylene transcriptional response remains elusive. We characterized the dynamic ethylene transcriptional response by identifying targets of the master regulator of the ethylene signaling pathway,(More)
A novel bioflocculant ZS-7 produced by Bacillus licheniformis X14 was investigated with regard to its synthesis and application to low temperature drinking water treatment. The effects of culture conditions including pH, carbon source, nitrogen source, temperature, inoculum size and shaking speed on ZS-7 production were studied. The purified bioflocculant(More)
We have previously shown that ASPP1 and ASPP2 are specific activators of p53; one mechanism by which wild-type p53 is tolerated in human breast carcinomas is through loss of ASPP activity. We have further shown that 53BP2, which corresponds to a C-terminal fragment of ASPP2, acts as a dominant negative inhibitor of p53 (ref. 1). Hence, an inhibitory form of(More)
Modeling dynamic regulatory networks is a major challenge since much of the protein-DNA interaction data available is static. The Dynamic Regulatory Events Miner (DREM) uses a Hidden Markov Model-based approach to integrate this static interaction data with time series gene expression leading to models that can determine when transcription factors (TFs)(More)
PURPOSE To demonstrate the relationships among tumour location, hydronephrosis, and tumour stage in patients with Upper Urinary Tract Urothelial Carcinoma (UUT-UC). Moreover, we want to determine whether primary tumour location is an independent predictor of prognosis in those patients. METHODS Retrospective analysis of 251 UUT-UC patients from our centre(More)
Acute promyelocytic leukemia (APL) is associated with chromosomal translocations, invariably involving the retinoic acid receptor alpha (RAR alpha) gene fused to one of several distinct loci, including the PML or PLZF genes, involved in t(15;17) or t(11;17), respectively. Patients with t(15;17) APL respond well to retinoic acid (RA) and other treatments,(More)
