Summary
N6-methyladenosine (m6A) impacts mRNA splicing, with splicing also influencing m6A deposition. Understanding this molecular interplay is key to cell function and disease.
Area of Science:
- Molecular Biology
- Epigenetics
- RNA Biology
Background:
- N6-methyladenosine (m6A) is the most prevalent mRNA modification.
- m6A regulators play a role in pre-mRNA splicing.
- Splicing mechanisms are increasingly recognized for their role in regulating m6A deposition.
Purpose of the Study:
- To investigate the intricate relationship between m6A modification and mRNA splicing.
- To elucidate the functional significance of the m6A-splicing interplay in cellular processes.
- To explore the implications of this molecular crosstalk in disease pathogenesis.
Main Methods:
- Loss-of-function studies of m6A regulators.
- Analysis of pre-mRNA splicing patterns.
- Investigation of m6A deposition dynamics in relation to splicing events.
Main Results:
- Loss-of-function studies confirm m6A regulators' involvement in pre-mRNA splicing.
- Evidence suggests that mRNA splicing actively prevents m6A deposition.
- The interplay between m6A and splicing is bidirectional and complex.
Conclusions:
- The interplay between m6A and mRNA splicing is a critical regulatory axis.
- Understanding this mechanism is vital for comprehending cell development and function.
- Dysregulation of m6A-splicing interactions may contribute to various diseases.

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.

02:23RNA Editing
9.0K
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...

01:32RNA Splicing
56.3K
Splicing is the process by which eukaryotic RNA is edited before its translation into protein. The RNA strand transcribed from eukaryotic DNA is called the primary transcript. The primary transcripts that become mRNAs are called precursor messenger RNAs (pre-mRNAs). Eukaryotic pre-mRNA contains alternating sequences of exons and introns. Exons are nucleotide sequences that code for proteins, whereas introns are the non-coding regions. In RNA splicing, introns are removed and exons are bonded...

01:35Pre-mRNA Processing: Modification of pre-mRNA Ends
9.3K
In eukaryotic cells, transcripts made by RNA polymerase are modified and processed before exiting the nucleus. Unprocessed RNA is called precursor mRNA or pre-mRNA to distinguish it from mature mRNA.
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a cap to the 5' end of the growing transcript. In this process, a 5' phosphate is replaced by modified guanosine that has a methyl group attached (7-methyl guanosine). This 5' cap helps...

01:53RNA Stability
33.5K
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...

02:18Alternative RNA Splicing
21.1K
Alternative RNA splicing is the regulated splicing of exons and introns to produce different mature mRNAs from a single pre-mRNA. Unlike in constitutive splicing where a single gene produces a single type of mRNA, alternative splicing allows an organism to produce multiple proteins from a single gene and plays an important role in protein diversity.
There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...
