Journal of Medical Genetics, 1964 Publisher Summary The term “sex chromatin,― denotes a body in the nuclei of cells, which shows a special relationship to the sex of the organism from which the cell originated. The sex-chromatin body is present in the nucleus only during interphase and disappears during mitosis.

Fun30 and Rtt109 Mediate Epigenetic Regulation of the DNA Damage Response Pathway in C. albicans
Journal of Fungi, 2022 Fun30, an ATP-dependent chromatin remodeler from S. cerevisiae, is known to mediate both regulation of gene expression as well as DNA damage response/repair. The Fun30 from C. albicans has not yet been elucidated. We show that C.

Current Biology, 2015 Chromatin is a complex of proteins, RNA and DNA that constitutes the physiological state of the genome. Its basic structure is essentially the same in nearly all eukaryotes, from single-celled yeasts to the most complex multicellular organisms (exceptions include the chromatin of dinoflagellates and vertebrate sperm). Its fundamental role is to package

Chromatin Boundaries and Chromatin Domains [PDF]
Cold Spring Harbor Symposia on Quantitative Biology, 2004 Insulator elements were first described in Drosophila, but subsequent studies have shown that they are present in vertebrates as well (for review, see West et al. 2002). Over the past several years we have focused our attention on the properties of an insulator at the 5énd of the chicken β-globin locus that has begun to provide an understanding of how ...

Histone H4 lysine 16 acetylation controls central carbon metabolism and diet-induced obesity in mice
Nature Communications, 2021 Misregulation of chromatin has been linked to many conditions, including obesity, but the details remain unclear. Here the authors identify the H4 lysine 16 acetyltransferase MOF as a master regulator of glucose metabolism that is required for normal ...

Aging is associated with increased chromatin accessibility and reduced polymerase pausing in liver
Molecular Systems Biology, 2022 Regulation of gene expression is linked to the organization of the genome. With age, chromatin alterations occur on all levels of genome organization, accompanied by changes in the gene expression profile.

Chromatin Loop Extrusion and Chromatin Unknotting [PDF]
Polymers, 2018 It has been a puzzle how decondensed interphase chromosomes remain essentially unknotted. The natural expectation is that in the presence of type II DNA topoisomerases that permit passages of double-stranded DNA regions through each other, all chromosomes should reach the state of topological equilibrium.

Frontiers in Cell and Developmental Biology, 2023 In vitro cell line model systems are essential in supporting the research community due to their low cost, uniform culturing conditions, homogeneous biological resources, and easy experimental design to study the cause and effect of a gene or a molecule.

Biophysical Journal, 2014 Following recent observations of large scale correlated motion of chromatin inside the nuclei of live differentiated cells, we present a hydrodynamic theory-the two-fluid model-in which the content of a nucleus is described as a chromatin solution with the nucleoplasm playing the role of the solvent and the chromatin fiber that of a solute. This system
