External factors influence organisms through epigenetic regulation. Cellular redox status changes, specifically in the nucleus, can alter epigenetic marks on histones, impacting health and disease treatment.
Area of Science:
- Molecular Biology
- Cellular Biology
- Epigenetics
Background:
- Epigenetic regulation explains environmental influences on organisms.
- Cellular redox status, particularly in the nucleus, is a key mediator.
- Redox changes are increasingly recognized as modulators of epigenetic processes.
Purpose of the Study:
- To explore the link between reactive oxygen and nitrogen species and epigenetic modifications.
- To highlight histone posttranslational modifications as central to redox-related epigenetics.
- To introduce the emerging field of redox-related epigenetic regulation.
Main Methods:
- Review of existing literature on reactive species and epigenetic marks.
- Focus on specific histone modifications: nitrosylation, carbonylation, and glutathionylation.
- Analysis of how cellular redox state influences epigenetic machinery.
Main Results:
- Reactive oxygen and nitrogen species induce epigenetic marks on histones.
- Posttranslational modifications like nitrosylation, carbonylation, and glutathionylation are key mechanisms.
- Redox-dependent epigenetic changes represent a significant area of biological research.
Conclusions:
- Redox-related epigenetic regulation is a critical interface between environment and organism.
- Understanding these mechanisms offers potential for treating various pathologies.
- This field holds significant promise for future biomedical research and therapeutic development.

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.
