This wealth of information coupled to the ease of genetic screening in nematodes has started to shed light on the mechanisms of genome folding inside the nuclear space. Worms have provided more than a mere description of the three-dimensional configuration of the genome, helped uncover functional ...
of human cells, which is also the case for the H19 non-translated RNA, but differs from the XIST RNA which is found predominantly in the nucleus. ... R, Wevrick,JA Kerns,U, Francke 被引量: 0发表: 2019年 rapid communication i dna inclusions within autolytic cytoplasmic vacuoles of hemo...
This diagram depicts covalent protein–DNA interactions within the nucleus. A step-by-step guide to successful chromatin immunoprecipitation (ChIP) assays This updated overview of the ChIP procedure includes additional detail about primary ant...
Different regions of interest (ROIs) for whole cell, nucleus and nucleoli were selected by using a rectangle or freehand shape around the different compartments. The threshold was automatically set within the software after Costes et al.22 and Pearson correlation coefficient and Mander’s overlap ...
we infected these clones in parallel with HIV-1-Luc and MLV (Murine Leukaemia Virus)-Luc. MLV requires mitosis to access the nucleus. Importantly, the clones proliferated similarly (Supplementary Fig. 1). After infection we detected a defect of Luc expression only in the HIV-1 infected clones...
We suggest that an asymmetric charge neutralization of DNA phosphate groups produces part of the driving force for nucleosome folding. In nucleosome core particle DNA, many of the phosphate groups are neutralized by histones, and a lateral alignment of these histones along the core DNA has been de...
The chromatin structure of DNA determines genome compaction and activity in the nucleus. On the basis of in vitro structures and electron microscopy (EM) studies, the hierarchical model is that 11-nanometer DNA-nucleosome polymers fold into 30- and subsequently into 120- and 300- to 700-nanomete...

The first stage of cell division. Before prophase begins, the chromosomes duplicate to form two long, thin strands called chromatids. During prophase itself, the chromatids condense and thicken and the membrane surrounding the nucleus disappears. In mitosis, prophase is followed by metaphase. See ...
