Summary
Metabolites and nutrients regulate RNA epigenetics through N6-methyladenosine (m6A) modification. This review explores how cellular metabolism influences m6A levels, impacting gene expression and cell fate.
Area of Science:
- Molecular Biology
- Epigenetics
- RNA Biology
Background:
- Cellular processes like growth and fate are controlled by epigenetic modifications of DNA and histones.
- RNA also undergoes diverse chemical modifications, with N6-methyladenosine (m6A) being the most prevalent.
- m6A modification is crucial for regulating RNA metabolism, including stability and translation, impacting development and disease.
Purpose of the Study:
- To review the current understanding of how metabolites and nutrients regulate m6A RNA modification.
- To explore the connection between cellular metabolic pathways and the m6A epitranscriptomic landscape.
Main Methods:
- Literature review of recent research on m6A modification.
- Analysis of enzymatic regulation (writers, erasers, readers) of m6A.
- Investigation of metabolite and nutrient roles as substrates or allosteric regulators.
Main Results:
- m6A modification is a reversible enzymatic process influenced by cellular metabolites.
- Nutrients and metabolic pathways directly impact the enzymes and substrates involved in m6A regulation.
- Metabolic state can alter m6A levels, affecting downstream RNA processing and cellular functions.
Conclusions:
- Metabolites and nutrients are critical regulators of the m6A epitranscriptome.
- Understanding these metabolic links provides insights into m6A's role in development and disease.
- Further research into metabolic regulation of m6A can reveal novel therapeutic targets.

01:53RNA Stability
34.8K
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...

02:23RNA Editing
9.5K
RNA editing is a post-transcriptional modification where a precursor mRNA (pre-mRNA) nucleotide sequence is changed by base insertion, deletion, or modification. The extent of RNA editing varies from a few hundred bases, in mitochondrial DNA of trypanosomes, to a just single base, in nuclear genes of mammals. Even a single base change in the pre-mRNA can convert a codon for one amino acid into the codon for another amino acid or a stop codon. This type of re-coding can significantly affect the...

01:23Regulation of Expression at Multiple Steps
1.2K
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...

02:31Nuclear Export of mRNA
8.2K
Before mRNAs are exported to the cytoplasm, it is crucial to check each mRNA for structural and functional integrity. Eukaryotic cells use several different mechanisms, collectively known as mRNA surveillance, to look for irregularities in mRNAs. Irregular or aberrant mRNA are rapidly degraded by various enzymes. If a defective mRNA escapes the surveillance, it would be translated into a protein which would either be non-functional or not function properly. One of the primary irregularities in...

02:24Regulation of Expression Occurs at Multiple Steps
24.4K
Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

01:19Regulation of Metabolism
10.8K
Cellular needs and conditions vary from cell to cell and change within individual cells over time. For example, the required enzymes and energetic demands of stomach cells are different from those of fat storage cells, skin cells, blood cells, and nerve cells. Furthermore, a digestive cell works much harder to process and break down nutrients during the time that closely follows a meal compared with many hours after a meal. As these cellular demands and conditions vary, so do the amounts and...
