Thermodynamic pathways to genome spatial organization in the cell nucleus [PDF]

open access: yes, 2009
The architecture of the eukaryotic genome is characterized by a high degree of spatial organization. Chromosomes occupy preferred territories correlated to their state of activity and, yet, displace their genes to interact with remote sites in complex ...

Mechanisms governing the accessibility of DNA damage proteins to constitutive heterochromatin

open access: yesFrontiers in Genetics, 2022
Chromatin is thought to regulate the accessibility of the underlying DNA sequence to machinery that transcribes and repairs the DNA. Heterochromatin is chromatin that maintains a sufficiently high density of DNA packing to be visible by light microscopy ...

Specific staining of human chromosomes in Chinese hamster x man hybrid cell lines demonstrates interphase chromosome territories [PDF]

open access: yes, 1985
In spite of Carl Rabl's (1885) and Theodor Boveri's (1909) early hypothesis that chromosomes occupy discrete territories or domains within the interphase nucleus, evidence in favor pf this hypothesis has been limited and indirect so far in higher plants ...

Rabl's model of the interphase chromosome arrangement tested in Chinise hamster cells by premature chromosome condensation and laser-UV-microbeam experiments [PDF]

open access: yes, 1982
In 1885 Carl Rabl published his theory on the internal structure of the interphase nucleus. We have tested two predictions of this theory in fibroblasts grown in vitro from a female Chinese hamster, namely (1) the Rabl-orientation of interphase ...

Systems biology in the cell nucleus [PDF]

open access: yesJournal of Cell Science, 2005
The mammalian nucleus is arguably the most complex cellular organelle. It houses the vast majority of an organism's genetic material and is the site of all major genome regulatory processes. Reductionist approaches have been spectacularly successful at dissecting at the molecular level many of the key processes that occur within the nucleus ...

Nuclear translocation of Cyclin B1 marks the restriction point for terminal cell cycle exit in G2 phase [PDF]

open access: yes, 2014
Upon DNA damage, cell cycle progression is temporally blocked to avoid propagation of mutations. While transformed cells largely maintain the competence to recover from a cell cycle arrest, untransformed cells past the G1/S transition lose mitotic ...

The Role of Nuclear Insulin and IGF1 Receptors in Metabolism and Cancer

open access: yesBiomolecules, 2021
Insulin (InsR) and insulin-like growth factor-1 (IGF1R) receptors mediate the metabolic and growth-promoting actions of insulin and IGF1/IGF2, respectively.

Transport in and out of the cell nucleus [PDF]

open access: yesBiochemical Society Transactions, 1998
A hallmark of eukaryotic cells is their separation into compartments. These compartments are surrounded by membranes that are impermeable to macromolecules. As most proteins are synthesised in the cytoplasm, specific transport systems have evolved to allow proteins to be imported from the cytoplasm into these compartments.

Modular Nanotransporters for Nuclear-Targeted Delivery of Auger Electron Emitters

open access: yesFrontiers in Pharmacology, 2018
This review describes artificial modular nanotransporters (MNTs) delivering their cargos into target cells and then into the nuclei – the most vulnerable cell compartment for most anticancer agents and especially for radionuclides emitting short-range ...
