Topoisomerase II inhibition can also induce DNA damage, which can be observed in HT-1080 cells as nuclear-wide H2AX phosphorylation in all cells after one hour of this treatment (Figure S1C [50].
An additional idea is that stability is actively maintained by ATP-dependent chromatin remodelling enzymes, an idea supported by the strong effects on nuclear-wide chromatin condensation caused by blocking ATP synthesis [44].
In addition to X chromosome inactivation the nucleolus is a key regulator of nuclear-wide heterochromatin organisation and inheritance and more recently stem cell differentiation programmes [ 47– 47].
Morphologically, few apoptotic bodies were noted, and additionally there was no evidence of the diffuse, nuclear-wide γH2AX labelling that has been associated with apoptosis [ 57].
A nuclear genome-wide comparison between cycads and other gymnosperms is definitely needed to clarify whether substitution rates are homogenously conserved across all three genomes of the cycads.
Here, we report the nuclear genome-wide base-substitution mutational properties of four sets of MA lines derived from two genotypes from each of two species of nematodes in the genus Caenorhabditis.
The original suggestion that A. darlingi is a species complex [ 17, 23] was refuted by Manguin and others [ 9] with a genetic and morphologic survey, although recent mitochondrial and nuclear range-wide studies provide support for the initial hypothesis [ 10, 28].
The lower boundary is the human-Neanderthal divergence, which Green et al. (2008) estimated as 520,000 to 800,000 years ago, based on mitochondrial genome analysis, whereas Green et al. (2010) estimated it as between 270,000 and 440,000 years ago, based on nuclear genome-wide analysis.
In nuclear graphite, the wide range of void sizes precludes a full characterisation of pore volume by means of a single technique.
Since last fall, North Korea has expelled I.A.E.A inspectors, renounced its participation in the Nuclear Nonproliferation Treaty and begun to accelerate its nuclear efforts, prompting wide speculation about its strategy.
They argue that while the Iranian government remains unpopular, the nuclear program has wide support in Iran, and one way to unite the people behind their rulers would be through an Israeli strike.
