Three-dimensional organization of promyelocytic leukemia dynamics of component exchange at pml nuclear bodies

Promyelocytic leukemia nuclear bodies (PML-NBs) are mobile subnuclear organelles formed by PML and Sp100 protein. They have been reported to have a role in transcription, DNA replication and repair, telomere lengthening, cell cycle control and tumor suppression. We have conducted high-resolution 4Pi fluorescence laser-scanning microscopy studies complemented with correlative electron dynamics of component exchange at pml nuclear bodies Sp100 Provides Intrinsic Immunity against Human dynamics of component exchange at pml nuclear bodies Most DNA viruses associate with, and reorganize, nuclear domain 10 (ND10) bodies upon entry into the host nucleus. In this study, we examine the roles of the ND10 components PML, Sp100, and Daxx in the establishment of human papillomavirus type 18 (HPV18) infection of primary human keratinocytes.

Mitotic accumulations of PML protein contribute to the re dynamics of component exchange at pml nuclear bodies

nuclear bodies: mobility and exchange of PML are altered In interphase, PML nuclear bodies are relatively immobile owing to extensive contacts with chromatin (Eskiw et al., 2004; Eskiw et al., 2003). When these chromatin contacts are disrupted by addition of transcriptional inhibitors such as actinomycin D or nucleases, PML nuclear bodies become Live Cell Dynamics of Promyelocytic Leukemia Nuclear Bodies dynamics of component exchange at pml nuclear bodies Promyelocytic leukemia nuclear bodies (PML NBs) have been proposed to be involved in tumor suppression, viral defense, DNA repair, and/or transcriptional regulation. To study the dynamics of PML NBs during mitosis, we developed several U2OS cell lines stably coexpressing PML-enhanced cyan fluorescent protein with other individual marker proteins. Cells | Free Full-Text | PML Bodies in Mitosis | HTML This is evident from the reduced component exchange rate of MAPPs compared to nuclear PML bodies, and the ability to aggregate into amorphous multi-body structures without undergoing fusion as would be expected for bodies in a liquid state [39,94,95]. The transition from a liquid to a solid state during entry into mitosis could, in part, be due dynamics of component exchange at pml nuclear bodies

Cell Cycle Dependent Alteration in NAC1 Nuclear Body Dynamics dynamics of component exchange at pml nuclear bodies

In contrast to NAC1 NBs, the quantity of PML NBs increased during S phase through nuclear body fission. FRAP experiments on PML NBs have shown that PML-V, one of the components in PML NBs, possesses a very slow exchange rate . This suggests that PML-V could play a structural role in building the basic frame of a stable PML NB. Assembly dynamics of PML nuclear bodies in living cells. For the first time, dynamics of PML body formation were measured in cells lacking endogenous PML. We show that all six human nuclear PML isoforms are able to form nuclear bodies in PML negative cells. All isoforms exhibit individual exchange rates at NBs in PML positive cells but PML I, II, III and IV are static at nuclear bodies in PML dynamics of component exchange at pml nuclear bodies Assembly dynamics of PML nuclear bodies in living cells | PMC dynamics of component exchange at pml nuclear bodies The mammalian cell nucleus contains a variety of organelles or nuclear bodies which contribute to key nuclear functions. Promyelocytic leukemia nuclear bodies (PML NBs) are involved in the regulation of apoptosis, antiviral responses, the DNA damage response and chromatin structure, but their precise biochemical function in these nuclear pathways is unknown.

PML nuclear bodies (NBs) are spheres of 0.11.0 m in diameter found in most cell-lines and many tissues. They belong to the nuclear matrix, an ill-defined super-structure of the nucleus proposed to anchor and regulate many nuclear functions, including DNA replication, transcription, or epigenetic silencing (Stuurman et al. 1990).

Nuclear body movement is determined by chromatin dynamics of component exchange at pml nuclear bodies

The artificial Mx1-yellow fluorescent protein body showed a very similar mobility compared with PML and Cajal bodies. The data are described quantitatively by a mechanism of nuclear body movement consisting of two components: diffusion of the body within a chromatin corral and its translocation resulting from chromatin diffusion.
