NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

10.3K
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.

Binge Eating Disorders01:23

Binge Eating Disorders

741
Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Clinical Medicine

Background:

  • Fibromyalgia (FM) and eating disorders (ED) are distinct conditions with significant comorbidity.
  • Shared pathophysiological mechanisms, particularly involving oxidative stress, are increasingly recognized.
  • Current understanding of these links and integrated treatments remains limited.

Purpose of the Study:

  • To review the role of oxidative stress and Nrf2 pathway dysfunction as a unifying mechanism in FM and ED.
  • To explore implications for integrated rehabilitation strategies.

Main Methods:

  • Narrative review of current evidence on oxidative stress in FM and ED.
  • Focus on Nrf2-Keap1 pathway, clinical comorbidity, and rehabilitation interventions.
  • PubMed searches included terms like "fibromyalgia", "eating disorders", "oxidative stress", and "Nrf2".

Main Results:

  • FM patients show elevated oxidative stress, reduced antioxidant function, and compromised Nrf2 activity.
  • EDs exhibit mitochondrial dysfunction and oxidative stress dysregulation.
  • Nrf2 regulates antioxidant defense and is influenced by energy balance, linking nutrition and cellular stress.

Conclusions:

  • Multidisciplinary rehabilitation targeting Nrf2 activation offers a mechanism-driven approach for FM and ED.
  • Nrf2 pathway dysfunction is a potential unifying molecular target for these conditions.
  • Further clinical trials in comorbid populations are needed to confirm Nrf2-targeted interventions.
