Melatonin as a potential modulator of Nrf2

Area of Science:

• Molecular Biology
• Biochemistry
• Pharmacology

Background:

• Oxidative stress contributes to numerous pathologies, damaging cellular components.
• Synthetic drugs for oxidative stress have limitations; natural compounds offer safer alternatives.
• Melatonin, a plant-derived hormone, exhibits diverse therapeutic properties including antioxidant and anti-inflammatory effects.

Purpose of the Study:

• To elucidate the role of the Nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway.
• To connect the Nrf2 pathway to the biological and therapeutic effects of melatonin.
• To highlight the potential of natural compounds in managing oxidative stress.

Main Methods:

• Review of existing scientific literature on Nrf2 signaling.
• Analysis of studies investigating melatonin's biological activities.
• Correlation of Nrf2 pathway activation with melatonin's observed effects.

Main Results:

• Nrf2 acts as a primary sensor for oxidative stress, maintaining cellular redox balance.
• The Nrf2 pathway mediates antioxidant and anti-inflammatory responses.
• Melatonin's therapeutic actions, including antioxidant and anti-inflammatory effects, are significantly explained by its interaction with the Nrf2 pathway.

Conclusions:

• The Nrf2 signaling pathway is a crucial mechanism underlying melatonin's beneficial effects.
• Melatonin represents a promising natural therapeutic agent for conditions associated with oxidative stress.
• Understanding the Nrf2-melatonin axis offers insights into novel therapeutic strategies.
