Histone acetylation in neuronal (dys)function
Biomolecular Concepts
|April 22, 2016
Summary
Histone acetylation regulates gene expression crucial for cognitive functions like learning and memory. Environmental factors can disrupt this process, leading to neurological disorders.
Area of Science:
- Neuroscience
- Molecular Biology
- Epigenetics
Background:
- Cognitive functions depend on regulated gene expression.
- Epigenetic modifications, particularly histone acetylation, are vital for neuronal functions like synaptic plasticity, learning, and memory.
Purpose of the Study:
- To review the molecular mechanisms of histone acetylation.
- To summarize the role of histone acetylation in cognitive functions under normal and pathological conditions.
- To discuss how environmental factors dysregulate histone acetylation in neurological disorders.
Main Methods:
- Review of existing scientific literature on histone acetylation and cognitive function.
- Analysis of molecular mechanisms underlying histone acetylation.
- Examination of data linking histone acetylation to neurological conditions and environmental influences.
Main Results:
- Histone acetylation is a key epigenetic mechanism regulating neuronal gene expression.
- Dysregulation of histone acetylation is implicated in cognitive impairments and neurological disorders.
- Environmental factors such as stress, drugs, and infections can negatively impact histone acetylation.
Conclusions:
- Histone acetylation is essential for normal cognitive function.
- Aberrant histone acetylation, often triggered by environmental factors, contributes to neurological disease.
- Targeting histone acetylation pathways may offer therapeutic strategies for cognitive and neurological disorders.

02:32Histone Modification
17.0K
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
9.9K
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.

01:32Chromatin Modification in iPS Cells
2.3K
Chromatin modification alters gene expression; therefore, scientists can add histone-modifying enzymes, histone variants, and chromatin remodeling complexes to somatic cells to aid reprogramming into pluripotent stem (iPS) cells.
Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...

02:04Covalently Linked Protein Regulators
9.9K
Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.

01:12The Nucleosome Core Particle
2.6K
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...
