Spatial repositioning of centromeric domains during regrowth of axons in nuclei of murine dorsal root ganglion neuronsin vitro

Autor: V. Choh, U. De Boni

Publikováno v: Journal of Neurobiology. 31:325-332

Specific chromatin domains within interphase nuclei are organized in cell type specific distributions and are rearranged in association with changes in cell function. Axotomy leads to changes in gene expression. Dorsal root ganglion (DRG) neurons in

Transposition of DNase hypersensitive chromatin to the nuclear periphery coincides temporally with nerve growth factor-induced up-regulation of gene expression in PC12 cells

Autor: U. De Boni, Paul C. Park

Publikováno v: Proceedings of the National Academy of Sciences. 93:11646-11651

To test the hypothesis that the nonrandom organization of the contents of interphase nuclei represents a compartmentalization of function, we examined the relative, spatial relationship of small nuclear ribonucleoproteins (snRNPs) and of DNase I hype

Spatial rearrangement and enhanced clustering of kinetochores in interphase nuclei of dorsal root ganglion neurons in vitro: Association with nucleolar fusion

Autor: U. De Boni, Paul C. Park

Publikováno v: Experimental Cell Research. 203:222-229

Interphase nuclei of several cell types display distinct, nonrandom arrangements of specific chromatin domains. It has been suggested that this arrangement is associated with the functional commitment of the cell and results from compartmentalization

Chromatin motion in neuronal interphase nuclei: Changes induced by disruption of intermediate filaments

Autor: U. De Boni, M. Hay

Publikováno v: Cell Motility and the Cytoskeleton. 18:63-75

Motion of nucleoli within interphase nuclei, known as nuclear rotation, may be used as a measure of motion of chromatin domains within the global confines of the nucleus. Mechanisms by which chromatin domains are transposed remain enigmatic. It has b

Dislocation of chromatin elements in prophase induced by diethylstilbestrol: a novel mechanism by which micronuclei can arise

Autor: Dietmar Schiffmann, U. De Boni

Publikováno v: Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis. 246:113-122

The in vitro micronucleus test with Syrian hamster embryo (SHE) cells assays the induction of micronuclei by chemical agents. Both chromosome fragments and lagging chromosomes can give rise to micronuclei. Nevertheless, only limited information is av

Association of DNAse sensitive chromatin domains with the nuclear periphery in 3T3 cells in vitro

Autor: J K, Chan, P C, Park, U, De Boni

Publikováno v: Biochemistry and cell biology = Biochimie et biologie cellulaire. 78(2)

DNAse sensitive chromatin, putative transcriptionally competent sequences, exists either as pan-nuclear speckles in cells with nuclei which exhibit a flat geometry, or as a shell apposed to the nuclear envelope in cells with spheroidal nuclei. To tes

Kindling-induced neurogenesis in the dentate gyrus of the rat

Autor: J.M. Wojtowicz, Brian W. Scott, W.M. Burnham, Sabrina Wang, U. De Boni

Publikováno v: Neuroscience letters. 248(2)

Kindling, a form of neuronal plasticity produced by repeated low intensity electrical brain stimulation, leads to epileptic seizures. To address possible causes of this phenomenon, we have prepared amygdala-kindled animals and measured neurogenesis,

A specific conformation of the territory of chromosome 17 locates ERBB-2 sequences to a DNase-hypersensitive domain at the nuclear periphery

Autor: U. De Boni, Paul C. Park

Publikováno v: Chromosoma. 107(2)

Chromatin in interphase nuclei exhibits a topology that is associated with the transcriptional state of cells. We examined the spatial, intranuclear distribution of chromosome 17 and the ERBB-2 (HER2/neu) sequence thereon, relative to that of DNase-h
