Chromatin structure in dementia
Annals of Neurology, 1984AbstractNuclei extracted from neocortex of patients with Alzheimer's disease and treated with micrococcal nuclease release a population of dinucleosomes that contain an increase in the linker histones H1° and H1ºº. Five other degenerative brain diseases that clinically resemble Alzheimer's disease do not result in these changes, although Pick's disease

Chromatin structure and epigenetics
Biochemical Pharmacology, 2006In eukaryotic cells, the DNA molecule is found in the form of a nucleoprotein complex named chromatin. The basic unit of the chromatin is the nucleosome, which comprises 147 base pairs of DNA wrapped around an octamer of core histones (made of two molecules of each H2A, H2B, H3, and H4 histones).

Structure of Replicating Chromatin
1996Publisher Summary This chapter summarizes the structural changes occurring in chromatin as replication-dependent events. The large genome of a eukaryotic cell is organized in the nucleus as a complex nucleoprotein structure, chromatin. The most dramatic changes in chromatin structure occur during genome replication, when advancing replication forks ...

Structure of Transcribing Chromatin
1980Publisher Summary This chapter discusses the recent studies in order to draw a contemporary picture of the structure of transcribing chromatin. The basic structure of “active” chromatin, unique, repeating, altered nucleosomal structure, is discussed in this chapter.

THE STRUCTURE OF EUKARYOTE CHROMATIN
Acta Endocrinologica, 1972ABSTRACT In this paper certain aspects of the structure of chromatin are considered, with emphasis on the relationships of histone and residual protein to DNA. Recent findings relative to the complexing of histone with DNA are reviewed and material from this laboratory concerning the ratio of total histone to DNA and related topics are ...

Supranucleosomal structure of chromatin
Cell Biology International Reports, 1978Rat liver chromatin was moderately digested by micrococcal nuclease and analysed by centrifugation in isokinetic sucrose gradients and electron microscopy. Two classes of particles sedimenting with about 33S and 60S were characterized. Kinetics of their appearance and disappearance during progressive digestion suggests that they represent monomers and ...

Structure of Chromatin in Spermatozoa
2013The specialized structure of the sperm chromatin has a dual function - first to protect the DNA from damage during storage and transport to the oocyte, and then to enable a rapid and complete unpacking of the undamaged paternal genome in the ooplasm. It is evident that zinc has a pivotal role in maintaining the structural stability and in enabling a ...

Critical Reviews in Eukaryotic Gene Expression, 1999
Independently of the enormous progress in our understanding of the structure of the core particle, there remain a multitude of structural questions still to be answered. The main points discussed here can be summarized as follows: (1) The meaning of the term 'core particle' should be widened to reflect the fact that the actual length of DNA wrapped ...
