Summary
Histone deacetylases (HDACs), specifically class I enzymes HDAC1 and HDAC2, are crucial for cell fate decisions and gene expression during organism development. This review details their roles in neurogenesis, myogenesis, and other key differentiation processes.
Area of Science:
- Developmental Biology
- Epigenetics
- Molecular Biology
Background:
- Cell fate determination and lineage specification are critical during multicellular organism development.
- Chromatin structure and modifying enzymes regulate gene expression patterns essential for differentiation.
- Histone deacetylases (HDACs) play vital roles in early development and cellular differentiation.
Purpose of the Study:
- To review the functions of class I histone deacetylases, HDAC1 and HDAC2, during organismal development.
- To summarize current knowledge on the involvement of HDAC1 and HDAC2 in key developmental processes.
Main Methods:
- Literature review of gene disruption studies across various genetic systems.
- Analysis of existing research on HDAC1 and HDAC2 functions in development.
Main Results:
- Class I HDACs, HDAC1 and HDAC2, are essential for proper development.
- These enzymes are involved in critical differentiation pathways including neurogenesis, myogenesis, haematopoiesis, and epithelial cell differentiation.
Conclusions:
- HDAC1 and HDAC2 are indispensable regulators of cell fate and gene expression during development.
- Understanding their roles provides insights into developmental processes and potential therapeutic targets.

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...

03:17Inheritance of Chromatin Structures
Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying DNA...
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,...

02:25Spreading 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.

01:14Maintenance of the ES Cell State
The cells of the blastocyst inner cell mass only remain pluripotent for a short time. This state of pluripotency and self-renewal can be maintained in embryonic stem (ES) cell culture by adding specific chemicals or growth factors to ensure the cells can continue dividing and later differentiate into different cell types. In some cases, the cells are grown on a feeder layer of differentiated cells, which provides the growth factors and extracellular matrix components necessary for stem cell...
