Insights

Nuclear factor erythroid 2-related factor 2 (NRF2) regulates cellular processes. Epigenetic modifications, like DNA methylation, can alter NRF2 expression, offering therapeutic targets for diseases through phytochemical activation.

Area of Science:

  • Molecular Biology
  • Epigenetics
  • Cellular Homeostasis

Background:

  • Nuclear factor erythroid 2-related factor 2 (NRF2) is a key transcription factor regulating cellular antioxidant and anti-inflammatory responses.
  • NRF2 activity is modulated by genetic and epigenetic mechanisms, including DNA methylation.
  • Aberrant NRF2 methylation patterns are linked to various diseases.

Purpose of the Study:

  • To review the role of NRF2 in cellular homeostasis and disease.
  • To explore the epigenetic regulation of NRF2, particularly DNA methylation.
  • To discuss the potential of natural phytochemicals in modulating NRF2 activity for therapeutic benefit.

Main Methods:

  • Literature review of studies on NRF2 regulation and function.
  • Analysis of research on epigenetic modifications affecting NRF2 expression.
  • Compilation of data on phytochemicals that activate NRF2.

Main Results:

  • Promoter hypermethylation of NRF2 has been shown to downregulate its expression.
  • Epigenetic changes affecting NRF2 are potentially reversible, unlike genetic mutations.
  • Numerous natural compounds, including sulforaphane and resveratrol, activate NRF2.

Conclusions:

  • Reversing hypermethylated NRF2 states via epigenetic modifications presents therapeutic opportunities.
  • Dietary phytochemistry can influence the human epigenome and NRF2 signaling.
  • Targeting NRF2 offers a promising strategy for preventing and treating chronic disorders.

Epigenetic Regulation01:37

Epigenetic Regulation

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.

Nucleosome Remodeling02:54

Nucleosome Remodeling

Nucleosomes are the basic units of chromatin compaction. Each nucleosome consists of the DNA bound tightly around a histone core, which makes the DNA inaccessible to DNA binding proteins such as DNA polymerase and RNA polymerase. Hence, the fundamental problem is to ensure access to DNA when appropriate, despite the compact and protective chromatin structure.

Chromatin Modification in iPS Cells01:32

Chromatin Modification in iPS Cells

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...

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
