Summary
DNA methylation, an epigenetic process regulated by DNA methyltransferases (DNMTs), influences gene transcription and chromatin structure. This review covers DNA demethylation strategies, including DNMT inhibition and TET enzymes, and their biomedical applications.
Area of Science:
- Epigenetics
- Molecular Biology
- Genetics
Background:
- DNA methylation is a key epigenetic mechanism regulating gene expression and chromatin architecture.
- DNA methyltransferases (DNMTs) catalyze the addition of methyl groups to cytosine in CpG dinucleotides.
- Dysregulation of DNA methylation is implicated in various cellular processes and diseases.
Purpose of the Study:
- To review common DNA demethylation strategies used over the past two decades.
- To discuss the cellular effects of different DNA demethylation methods.
- To explore emerging techniques in DNA methylation research and their biomedical relevance.
Main Methods:
- Review of established DNA demethylation techniques, including DNMT inhibition (passive demethylation) and TET enzyme activity (active demethylation).
- Discussion of novel inducible DNMT inhibition strategies with minimal side effects.
- Exploration of the role of non-coding RNAs in modulating DNA methylation patterns.
Main Results:
- Various strategies exist for manipulating DNA methylation, impacting gene transcription and cellular functions.
- Active and passive DNA demethylation methods yield distinct cellular outcomes.
- Emerging methods offer precise control over DNA methylation with potential therapeutic benefits.
Conclusions:
- Understanding DNA demethylation mechanisms is crucial for deciphering epigenetic regulation.
- Novel strategies for inhibiting DNMTs and the influence of non-coding RNAs offer new avenues for research.
- DNA methylation inhibition holds promise for applications in biomedical research and disease treatment.

Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

01:37Epigenetic Regulation
3.5K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

01:32Chromatin Modification in iPS Cells
1.5K
Chromatin modification alters gene expression; therefore, scientists can add histone-modifying enzymes, histone variants, and chromatin remodeling complexes to somatic cells to aid reprogramming into pluripotent stem (iPS) cells.
Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...

01:17Phase II Reactions: Methylation Reactions
915
Methylation is a phase II biotransformation process involving the attachment of a methyl group to a substrate. Enzymes known as methyltransferases orchestrate this reaction.
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...

01:30Spontaneous and Induced Mutations
3.2K
Spontaneous mutations arise infrequently during DNA replication due to errors in the process. A key factor behind these errors is tautomeric shifts in nitrogenous bases, where bases transition from keto to enol forms or amino to imino forms. This shift can alter base-pairing rules, leading to mutations. Additionally, reactive oxygen species (ROS) arising from aerobic metabolism can damage DNA, resulting in depurination (loss of a purine base) or depyrimidination (loss of a pyrimidine base).
