Summary
Nonsense-mediated mRNA decay (NMD) regulates gene expression by degrading faulty transcripts. Individual differences in NMD efficiency impact genetic disease severity and treatment outcomes.
Area of Science:
- Molecular Biology
- Genetics
- Human Disease
Background:
- Nonsense-mediated mRNA decay (NMD) is a crucial cellular surveillance pathway.
- NMD degrades messenger RNA (mRNA) with premature termination codons (PTCs).
- PTCs arise from mutations causing about one-third of human genetic diseases.
Purpose of the Study:
- To review evidence for inter-individual variability in NMD efficiency.
- To explore genetic factors contributing to NMD variability.
- To discuss the implications of NMD variability for human diseases and therapeutics.
Main Methods:
- Literature review of studies on NMD efficiency and genetic variations.
- Analysis of existing data correlating NMD levels with clinical outcomes.
- Examination of genetic factors influencing NMD pathway regulation.
Main Results:
- Evidence supports significant inter-individual variability in NMD efficiency.
- This variability correlates with disease presentation and drug response.
- Genetic factors are identified as key drivers of NMD efficiency differences.
Conclusions:
- Inter-individual NMD efficiency variation is a common phenomenon.
- NMD efficiency influences the impact of PTC-generating mutations in genetic disorders.
- Considering individual NMD efficiency is vital for disease diagnosis and therapeutic strategies.

The Upf proteins that carry out nonsense-mediated decay (NMD) are found in all eukaryotic organisms, including humans. Each protein has an individual role, but they need to work in collaboration. Upf1 is an ATP-dependent RNA helicase that unwinds the RNA helix. Because Upf1 can unwind any RNA, Upf2 and Upf3 are required to help Upf1 discriminate between nonsense and normal mRNAs.
Usually, Upf3 binds to an Exon Junction Complex (EJC) at mRNA splice sites. If a ribosome fully translates the mRNA,...

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...

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.

Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
