Insights

Nuclear factor erythroid 2-related factor 2 (Nrf2) normally protects cells from oxidative stress. However, persistent Nrf2 activation can paradoxically cause harm, requiring further study into its detrimental roles.

Area of Science:

  • Cellular Biology
  • Molecular Biology
  • Biochemistry

Background:

  • Nuclear factor erythroid 2-related factor 2 (Nrf2) is a transcription factor regulating antioxidant response.
  • Under basal conditions, Nrf2 is degraded, but oxidative stress promotes its nuclear translocation and activation.
  • Nrf2 activation confers protective antioxidant properties, extensively documented in various disease models.

Purpose of the Study:

  • To review the dual role of Nrf2 in pathological conditions.
  • To highlight mechanisms and contexts where Nrf2 activation leads to adverse outcomes.
  • To underscore the need for further research into the detrimental effects of persistent Nrf2 activation.

Main Methods:

  • Literature review of studies investigating Nrf2's role in disease.
  • Analysis of pathological contexts associated with Nrf2.
  • Examination of molecular mechanisms underlying Nrf2's beneficial and harmful effects.

Main Results:

  • Nrf2 activation is protective in many diseases.
  • Emerging evidence indicates that sustained Nrf2 activation can be detrimental.
  • Specific pathological conditions and molecular mechanisms mediate Nrf2's adverse effects.

Conclusions:

  • The role of Nrf2 is context-dependent, exhibiting both protective and harmful functions.
  • Persistent Nrf2 activation may lead to deleterious consequences.
  • Further investigation is crucial to elucidate the specific conditions and mechanisms driving Nrf2's harmful actions.

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.

Transducer Mechanism: Nuclear Receptors01:31

Transducer Mechanism: Nuclear Receptors

Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:

Electron Transport Chain: Complex I and II01:46

Electron Transport Chain: Complex I and II

The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...

Regulation of the Unfolded Protein Response01:31

Regulation of the Unfolded Protein Response

Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...

Circadian Rhythms and Gene Regulation

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...

Aging

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...
