Summary
Cell-type-specific gene expression during development relies on enhancers. This review explores how histone and DNA modifications regulate these crucial elements and their functional significance in embryogenesis.
Area of Science:
- Developmental Biology
- Epigenetics
- Genomics
Background:
- Embryogenesis involves cell-type-specific gene expression regulated by enhancers.
- Large-scale epigenomic studies have identified numerous human enhancers with complex utilization patterns.
- Enhancers share characteristic chromatin features, but their functional modification remains unclear.
Purpose of the Study:
- To provide an overview of enhancer-associated histone and DNA modifications.
- To discuss enzymes involved in the dynamic regulation of these modifications.
- To explore the functional significance of chromatin modifications in enhancer activity during development.
Main Methods:
- Literature review of enhancer-associated chromatin modifications.
- Discussion of enzymatic activities in mark deposition and removal.
- Proposal of models for studying chromatin modification functions.
Main Results:
- Enhancers are regulated by specific histone and DNA modifications.
- Enzymatic activities dynamically control these epigenetic marks.
- Understanding these modifications is key to deciphering enhancer function.
Conclusions:
- Chromatin modifications play a critical role in regulating enhancer activity.
- Further research into these modifications will illuminate developmental processes.
- This review synthesizes current knowledge and proposes future research directions.

02:25Spreading of Chromatin Modifications
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
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...

02:05Duplication of Chromatin Structure
The process of chromosome duplication during cell division requires genome-wide disruption and re-assembly of chromatin. The chromatin structure must be accurately inherited, reassembled, and maintained in the daughter cells to ensure lineage propagation.
The basic unit of the chromatin is the nucleosome, consisting of DNA wrapped around octameric histone proteins and short stretches of linker DNA separating individual nucleosomes. The histone proteins within the nucleosome have their...

02:32Histone Modification
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.
Acetylation
The enzyme histone acetyltransferase adds acetyl group to the histones. Another enzyme, histone deacetylase,...

02:54Nucleosome Remodeling
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.
