Several pathways have been implicated in the establishment of antiviral state in response to interferon (IFN), one of which implicates the promyelocytic leukemia (PML) protein. The PML gene has been discovered 20 years ago and has led to new insights into oncogenesis, apoptosis, cell senescence, and antiviral defense. PML is induced by IFN, leading to a marked increase of expression of PML isof...
Arsenic is a clinically effective treatment for acute promyelocytic leukaemia (APL) in which the promyelocytic leukaemia (PML) protein is fused to retinoic receptor alpha (RARα). PML-RARα is degraded by the proteasome by a SUMO-dependent, ubiquitin-mediated pathway in response to arsenic treatment, curing the disease. Six major PML isoforms are expressed as a result of alternative splicing, eac...
PML-RARA was proposed to initiate acute promyelocytic leukemia (APL) through PML-RARA homodimer-triggered repression. Here, we examined the nature of the PML-RARA protein complex and of its DNA targets in APL cells. Using a selection/amplification approach, we demonstrate that PML-RARA targets consist of two AGGTCA elements in an astonishing variety of orientations and spacings, pointing to hig...
Nuclear domain 10 (ND10), also referred to as nuclear bodies, are discrete interchromosomal accumulations of several proteins including promyelocytic leukemia protein (PML) and Sp100. In this study, we investigated the mechanism of ND10 assembly by identifying proteins that are essential for this process using cells lines that lack individual ND10-associated proteins. We identified the adapter ...
In anisotropic media, the standard perfectly matched layer (PML) technique suffers irrevocable instability in terminating unbounded problem domains. It remains an open question whether a stable PML-like absorbing boundary condition exists. For wave scattering layered orthotropic medium, this is affirmatively answered for first time paper. each permittivity tensor uniquely determines change of c...
Promyelocytic leukemia (PML) nuclear bodies selectively associate with transcriptionally active genomic regions, including the gene-rich major histocompatibility (MHC) locus. In this paper, we have explored potential links between PML and interferon (IFN)-γ-induced MHC class II expression. IFN-γ induced a substantial increase in the spatial proximity between PML bodies and the MHC class II gene...
p73 has been identified recently as a structural and functional homologue of the tumor suppressor p53. Here, we report that p73 stability is directly regulated by the ubiquitin-proteasome pathway. Furthermore, we show that the promyelocytic leukemia (PML) protein modulates p73 half-life by inhibiting its degradation in a PML-nuclear body (NB)-dependent manner. p38 mitogen-activated protein kina...
Promyelocytic Leukemia (PML) is a nuclear protein that forms sub-nuclear structures termed nuclear bodies associated with transcriptionally active genomic regions. PML is a tumour suppressor and regulator of cell differentiation. We demonstrate that PML promotes TNFα-induced transcriptional responses by promoting NF-κB activity. TNFα-treated PML-/- cells show normal IκBα degradation and NF-κB n...
The bcr1- and bcr3- promyelocytic leukemia/retinoic acid receptor alpha (PML/RAR alpha) are the two major fusion proteins expressed in acute promyelocytic leukemia (APL) patients. These proteins, which are present in different lengths of PML (amino acids 1-552 and 1-394, respectively), contain most of the functional domains of PML and RAR alpha, bind all-trans-retinoic acid (t-RA), and act as t...
The functional activities of the tumor suppressor promyelocytic leukemia protein (PML) are mostly associated with its nuclear location. In the present study, we discovered an unexpected role of PML in NLRP3 inflammasome activation. In PML-deficient macrophages, the production of IL-1β was strongly impaired. The expression of pro-IL-1β, NLRP3, ASC, and procaspase-1 was not affected in Pml(-/-) m...
