Summary
The function of N6-methyladenosine (m6A) methylation in RNA has been unclear. This study reveals m6A regulates RNA processing and stabilizes the mammalian circadian clock’s rhythm.
Area of Science:
- Biochemistry
- Molecular Biology
- Chronobiology
Background:
- N6-methyladenosine (m6A) is the most prevalent internal modification in eukaryotic messenger RNA.
- The biological significance of m6A has remained largely enigmatic since its discovery in the 1970s.
Purpose of the Study:
- To elucidate the functional role of m6A methylation in RNA.
- To investigate the impact of m6A on the mammalian circadian clockwork.
Main Methods:
- The study likely involved molecular biology techniques to analyze RNA modifications and circadian rhythms.
- Specific methods may include RNA sequencing, gene expression analysis, and manipulation of m6A levels.
Main Results:
- Fustin et al. demonstrate that m6A methylation plays a crucial role in regulating RNA processing.
- The findings indicate that m6A influences the period and stability of oscillations in the mammalian circadian clock.
Conclusions:
- m6A methylation is essential for proper RNA processing.
- This modification is a key determinant of the robustness and timing of the mammalian circadian clock.

The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

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.

The structure and stability of mRNA molecules regulates gene expression, as mRNAs are a key step in the pathway from gene to protein. In eukaryotes, the half-life of mRNA varies from a few minutes up to several days. mRNA stability is essential in growth and development. The absence of the proteins regulating its stability, such as tristetraprolin in mice, can cause systemic issues, including bone marrow overgrowth, inflammation, and autoimmunity.

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...
