Molecular genetics of gliomas.
Gambia. In Cancer J, 31 Jan 2014
Pediatric GBMs have a distinctive molecular pathogenesis, as H3F3A and DAXX mutations are frequent, and their gene expression profile is different than adult GBMs.
Virion factors that target Daxx to overcome intrinsic immunity.
Hamburg, Germany. In J Virol, Oct 2013
A number of recent reports suggest that several virion proteins may also play vital roles in gene activation processes, in particular by counteracting intrinsic immune mechanisms mediated by the PML nuclear body-associated cellular factors Daxx, ATRX, and Sp100.
Neuroendocrine tumours: cracking the epigenetic code.
London, United Kingdom. In Endocr Relat Cancer, Jun 2013
Recent progress has been facilitated by development of high-throughput tools including second-generation sequencing and arrays for analysis of the 'epigenome' of tumour and normal tissue, permitting unbiased approaches such as exome sequencing that identified mutations of chromatin-remodelling genes ATRX/DAXX in 44% of pancreatic NETs.
Driver mutations in histone H3.3 and chromatin remodelling genes in paediatric glioblastoma.
Montréal, Canada. In Nature, 2012
Mutations in ATRX (α-thalassaemia/mental retardation syndrome X-linked) and DAXX (death-domain associated protein), encoding two subunits of a chromatin remodelling complex required for H3.3 incorporation at pericentric heterochromatin and telomeres, were identified in 31% of samples overall, and in 100% of tumours harbouring a G34R or G34V H3.3 mutation.
Interplay between human cytomegalovirus and intrinsic/innate host responses: a complex bidirectional relationship.
Bologna, Italy. In Mediators Inflamm, 2011
We review the viral and cellular partners that mediate early host responses to HCMV with regard to the interaction between structural components of virions (viral glycoproteins) and cellular receptors (attachment/entry receptors, toll-like receptors, and other nucleic acid sensors) or intrinsic factors (PML, hDaxx, Sp100, viperin, interferon inducible protein 16), the reactions of innate immune cells (antigen presenting cells and natural killer cells), the numerous mechanisms of viral immunoevasion, and the potential exploitation of events that are associated with early phases of virus-host interplay as a therapeutic strategy.
Role of promyelocytic leukemia protein in host antiviral defense.
Paris, France. In J Interferon Cytokine Res, 2011
PML is the organizer of the NBs that contains at least 2 permanent NB-associated proteins, the IFN-stimulated gene product Speckled protein of 100 kDa (Sp100) and death-associated dead protein (Daxx), as well as numerous other transient proteins recruited in these structures in response to different stimuli.
