chromatin

Eukaryotic genomes are packaged into a nucleoprotein complex known as chromatin, which affects most processes that occur on DNA.

To me, only the 2 cells in left lower photo are suspicious for HSIL, but the nuclei are too dark and i cannot see the chromatin pattern.

This chromatin is called heterochromatin. The chromatin which stains less deeply than heterochromatin is called euchromatin.

In this condition , they are sometimes referred to collectively as the chromatin of the nucleus .

Although chromatin condensation is one of the hallmarks of apoptosis, its relationship with DNA fragmentation has been controversial.

Chromosome --- One of the threadlike structures in the cell nucleus; consists of chromatin and carries genetic information (DNA).

Nuclear actin is involved in a variety of nuclear processes including transcription, chromatin remodeling, and intranuclear transport.

Human embryos do not provide enough time for chromatin remodeling, thus preventing the cloning of humans using adult cells.

Chromatin contains half as much DNA as it does protein, most of which is in the form of histones .

Eukaryotic DNA is organized as a nucleoprotein polymer termed chromatin with nucleosomes serving as its repetitive architectural units.

However, few studies have taken advantage of DNA quantification by fluorometry for dynamic assessment of chromatin organization.

Instead, chromatin is dynamic and is subject to extensive developmental and age-associated remodeling.

"We found that nicotine works on the DNA-packaging system, known as chromatin, " says Levine.

The central axial area of each chromatid is a low electronic density region or chromatin free compartment , in which there are lots of RNP.

These maps suggest a pervasive involvement of transcriptional activity in indexing chromatin with reference to the underlying DNA sequence.

Alterations in nucleosome structure affect the accessibility of the DNA and can generate specialized domains of chromatin in the genome.

Chromatin modifications are important for all cellular processes that involve DNA, including transcription, replication and DNA repair.

Optical microscope observation demonstrated the formation of apoptotic bodies and the condensation of nuclear chromatin after DAPI staining.

Recent data implicate transcriptional repressors specific for methylated DNA and chromatin assembly in this global control of gene activity.

considerable variation in nuclear size, shape, and chromatin content; mitoses are frequent and may be abnormal.

The latter group is used to describe the eu- and hetero-chromatin in a way complementing the textural methods.

At high magnification, the non-Hodgkin's lymphoma cells have prominent clumped chromatin and nucleoli with occasional mitotic figures.

These features include cell volume, cell shape, chromatin distribution, intranuclear voids, and the ratio of nuclear to cytoplasmic volume.

Eukaryotes have developed intricate mechanisms to overcome this repressive barrier imposed by chromatin.

Histone marks affect splicing outcome by influencing the recruitment of splicing regulators via a chromatin-binding protein.

Covalent modifications of histone tails play a key role in the regulation of chromatin structure and control of transcriptional activity.

Fluorescence in situ hybridization (FISH) technique is a most effective method of detecting alien chromatin at molecular level.

Inhibition of tyrosine dephosphorylation prevents apoptotic chromatin condensation but not DNA fragmentation.

The RBC in the center of the field contains several Howell-Jolly bodies, or inclusions of nuclear chromatin remnants.

Configuration of germinal vesicle (GV) chromatin has been studied and found correlated with the developmental competence of oocytes.

Covalent modification of histones on chromatin is a dynamic mechanism by which various nuclear processes are regulated.

the contraction of chromatin towards one side of the nucleus during the prophase of meiosis.

Each long strand of DNA combines with histones and nonhistone proteins to make up the substance chromatin.

The protein-DNA nucleosome complexes, in turn, are packed into repeating units called chromatin, which is the building block of chromosomes.

The nuclei are ovoid or round with finely reticular chromatin and rare punctate nucleoli. The cytoplasm is pale eosinophilic or clear.

DNA methylation has an important role in transcriptional regulation, togethering with histone modification and chromatin remodeling.

transcription cofactors and chromatin-modifying enzymes.

By slightly changing shape, chromatin may expose different genes to the transcription machinery.

Chromatin proteins are essentially the packaging for DNA, holding chromosomes in well-defined spirals.

Packaging DNA into chromatin is pivotal for the regulation of genome activity in eukaryotes.

Histone lysine methylation plays a key role in the organization of chromatin structure and the regulation of gene expression.

The acrosome is surrounded with nuclear cup which contains filamentous or granular chromatin.

Subsequently, chromatin is isolated from nuclei and subjected to sonication.

cell nucleolus bursted in membrane, nucleolus swelled or disappeared and agglutinated with chromatin together.

Histone proteins both protect DNA and regulate genes as they combine with DNA to form chromatin.

With this technique, total chromatin is first cut into single nucleosome-sized pieces.

Luger and her colleagues next packaged the modified histones they received from Shokat's group into recombinant nucleosomes and chromatin.

Covalent histone modifications and ATP-dependent chromatin remodeling play important roles in the process of DNA repair.

The epigenetic profile of germ cells, which is defined by modifications of DNA and chromatin, changes dynamically during their development.

SATB1 also globally regulates histone status in the chromatin by recruiting histone-modifying enzymes to the target-gene loci.

It focuses on the proteins that control plant gene expression at the chromatin level.

We are particularly interested in the roles of chromatin modifications in DNA damage response.

Recent progress has changed our view of how these complexes are recruited, and how they affect chromatin and repress gene activity.

However, the highly condensed structure of chromatin imposes significant obstacles on the repair processes.

Chromosome breakpoints detected in T cell cancers frequently reside in chromatin regions associated with H3K4 methylations.

The chromatin is vesicular, and small nucleoli are present.

It is also controlled by specific changes in chromatin structure in the vicinity of lineage-specific genes.

The structure of the nucleosome core particle of chromatin in chicken erythrocytes has been examined by using AFM.

Recent data link changes in gene expression to chromatin remodeling, such as histone modifications and histone replacement.

The reason is that there are some boundary elements that separating chromatin into different domains.

It is this that is visible as the typical looped threadlike chromatin material of the non dividing chromosome.
