Repressing Gene Transcription by Redirecting Cellular Machinery with Chemical Epigenetic Modifiers
Published on: September 20, 2018
Summary
The "histone code" hypothesis integrates new findings on histone variants and post-translational modifications. This explains how chromatin structure regulates gene transcription, advancing our understanding of gene activity control.
Area of Science:
- Molecular Biology
- Genetics
- Epigenetics
Context:
- Histones are key proteins in chromatin structure, influencing gene expression.
- Early research on histones and transcription yielded conflicting results.
- Nucleosome structure was initially considered highly conserved.
Purpose:
- To review the current understanding of chromatin organization.
- To discuss the role of chromatin in regulating gene transcription.
- To explore the
- histone code
- hypothesis.
Summary:
- Recent discoveries reveal diverse histone variants and post-translational modifications.
- These modifications and variants allow for varied nucleosomal particle assembly.
- Specific histone modifications and variants correlate with active or inactive chromatin states.
Impact:
- Advances the understanding of gene regulation mechanisms.
- Provides a framework for integrating complex chromatin data.
- Highlights the dynamic nature of chromatin in controlling gene activity.

Chromatin Structure Regulates pre-mRNA Processing
In eukaryotic cells, nascent mRNA transcripts need to undergo many post-transcriptional modifications to reach the cell cytoplasm and translate into functional proteins. For a long time, transcription and pre-mRNA processing were considered two independent events that occur sequentially in the cell. However, it has now been well established that transcription and pre-mRNA processing are two simultaneous processes that are precisely regulated inside the cell.

Co-activators and Co-repressors
Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...

Euchromatin
The extent of chromatin compaction can be studied by staining chromatin using specific DNA binding dyes. Under the microscope, the dense-compacted regions take up more dye, appearing darker, while the less-compact areas take up less dye and appear lighter. Based on the compaction level, chromatins are classified into two primary forms – euchromatin and heterochromatin.
Euchromatin is the less dense region of the chromatin and stains lighter. Euchromatin contains histone H3 extensively...

Duplication 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...
