Summary
Epitranscriptomics now includes chromatin-associated RNAs (caRNAs) and their methylation. This RNA modification influences gene expression and cellular phenotypes, opening new therapeutic avenues.
Area of Science:
- Molecular Biology
- Epigenetics
- RNA Biology
Background:
- Epitranscriptomics studies chemical modifications of RNA.
- N6-methyladenosine (m6A) is a key RNA modification, primarily studied in messenger RNAs (mRNAs).
- Emerging research shows m6A also modifies chromatin-associated RNAs (caRNAs).
Purpose of the Study:
- To review recent findings on the interplay between caRNAs and chromatin architecture.
- To explore the impact of RNA methylation on caRNA function.
- To highlight techniques for profiling caRNAs and their modifications.
Main Methods:
- Literature review of recent studies.
- Focus on genome-wide profiling techniques.
- Analysis of caRNA-chromatin interactions.
Main Results:
- caRNAs interact dynamically with chromatin architecture.
- RNA methylation significantly impacts caRNA function in this interplay.
- Enabling techniques have advanced genome-wide profiling of caRNAs and modifications.
Conclusions:
- The study of RNA methylation in caRNAs expands epitranscriptomics.
- These modifications offer new insights into gene expression regulation and cellular phenotypes.
- Further research in relevant biological systems is needed, with potential therapeutic implications.

02:41Chromatin Structure Regulates pre-mRNA Processing
7.0K
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.

01:37Epigenetic Regulation
3.0K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

02:25Spreading of Chromatin Modifications
8.2K
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.

01:53RNA Stability
33.3K
Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

01:20Types of RNA
5.7K
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in regulating gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

03:17Inheritance of Chromatin Structures
6.2K
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...
