Summary
Researchers developed DNA-histone networks (DHN) as model extracellular traps (ETs). These DHN allow controlled study of ET structure, enzyme degradation, thrombosis, and antimicrobial activity.
Area of Science:
- Biochemistry
- Immunology
- Cell Biology
Background:
- Extracellular traps (ETs) are released by blood cells during ETosis.
- ETs play roles in host defense and pathological processes.
- Native ETs are structurally heterogeneous, complicating pathophysiological studies.
Purpose of the Study:
- To develop model extracellular traps (ETs) with controlled composition and structure.
- To create DNA-histone networks (DHN) as model ETs.
- To enable detailed investigation of ET structure-function relationships.
Main Methods:
- Developing a method to create DNA-histone networks (DHN).
- Investigating the effect of DNA/histone weight ratio on DHN structure.
- Incorporating myeloperoxidase into DHN.
Main Results:
- DHN structure is dependent on the DNA/histone weight ratio.
- Myeloperoxidase can be successfully incorporated into DHN.
- Demonstrated the feasibility of creating model ETs with controlled composition.
Conclusions:
- DHN serve as valuable models for studying native ETs.
- Controlled DHN facilitate assessment of enzyme systems degrading ETs.
- DHN can be used to investigate ET-induced thrombosis and antimicrobial activity.

02:54Nucleosome Remodeling
9.5K
Nucleosomes are the basic units of chromatin compaction. Each nucleosome consists of the DNA bound tightly around a histone core, which makes the DNA inaccessible to DNA binding proteins such as DNA polymerase and RNA polymerase. Hence, the fundamental problem is to ensure access to DNA when appropriate, despite the compact and protective chromatin structure.

01:12The Nucleosome Core Particle
1.2K
Nucleosomes are the DNA-histone complex, where the DNA strand is wound around the histone core. The histone core is an octamer containing two copies of H2A, H2B, H3, and H4 histone proteins.
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their primary aim is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. On the other hand, they must allow polymerase enzymes to access histone-bound DNA during...

17.2K
Each human somatic cell contains 6 billion base pairs of DNA. Each base pair is 0.34 nm long, meaning each diploid cell contains a staggering 2 meters of DNA. This long DNA strand is packed inside a nucleus measuring only 10-20 microns in diameter with the help of specialized DNA-binding proteins called histones. Together they form a compact DNA-protein complex called chromatin. The chromatin is further compacted into higher-order structures. The highest level of compaction is achieved during...

02:32Histone Modification
13.8K
The histone proteins have a flexible N-terminal tail extending out from the nucleosome. These histone tails are often subjected to post-translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination. Particular combinations of these modifications form “histone codes” that influence the chromatin folding and tissue-specific gene expression.

02:25Spreading of Chromatin Modifications
8.5K
The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.

2.4K
Human DNA is almost two meters long. However, it is compressed inside a tiny nucleus measuring only a few microns in diameter. To make this degree of compaction possible, DNA is organized into several sequential levels so that it can fit into such a tiny space. The most compact form of DNA is a chromosome that can be seen under a microscope in a dividing cell.
In a chromosome, DNA is wound twice around a protein complex called a histone octamer core, which consists of 8 histone proteins. This...
