Melatonin treatment during REM sleep deprivation modulates oxidative stress-related parameters by increasing enzymatic antioxidant levels and reducing lipid peroxidation in rats

In a six-day REM sleep deprivation model using the modified multiple platform method, melatonin treatment increased enzymatic antioxidant levels (CAT, SOD, GPx) and reduced lipid peroxidation (MDA) in male Sprague-Dawley rats. Effects on total oxidant status were not significant, and total antioxidant status changes were limited and time-dependent. During recovery, some oxidative stress markers partially normalized, suggesting reactivation of endogenous antioxidant defenses.

Melatonin treatment during REM sleep deprivation modulates oxidative stress-related parameters by increasing enzymatic antioxidant levels and reducing lipid peroxidation in rats The current body of evidence comprises 1 study. EvidenceHub rates the overall confidence at 24/100 (low).

The Claim

Melatonin treatment during REM sleep deprivation modulates oxidative stress-related parameters by increasing enzymatic antioxidant levels and reducing lipid peroxidation in rats

This conclusion is most relevant to: 8-12-week-old male Sprague-Dawley rats (n=84).

What the Research Shows

The conclusion draws on 1 linked study. Highlights from the cited literature:

  • Effect of melatonin treatment on oxidative stress-related parameters in REM sleep-deprived rats. (Molecular and cellular biochemistry, 2026) —

How It Works

The proposed biological pathway:

  • REM sleep deprivation increases oxidative stress via ROS accumulation and disrupts oxidant-antioxidant balance
  • Melatonin acts as a direct ROS scavenger
  • Melatonin supports endogenous antioxidant defense mechanisms
  • Melatonin increases enzymatic antioxidant levels and reduces lipid peroxidation
  • Result: Attenuation of some oxidative stress alterations, with effects varying by timing and parameter

Who Might Benefit

Evidence fit by population:

  • 8-12-week-old male Sprague-Dawley rats (n=84)

Limitations & Caveats

Important context when interpreting this evidence:

  • Animal study (rats), not directly generalizable to humans
  • Specific dose and administration route of melatonin not reported in abstract
  • Only six-day REM-SD period; long-term effects not assessed
  • No significant change in TOS, and TAS effect limited and time-dependent

Frequently Asked Questions

Does melatonin reduce oxidative stress caused by REM sleep deprivation?

Yes, in this rat study, melatonin treatment increased enzymatic antioxidant levels and reduced lipid peroxidation, but did not significantly affect total oxidant status.

What oxidative stress markers were measured in this study?

Total antioxidant status (TAS), total oxidant status (TOS), malondialdehyde (MDA), glutathione (GSH), catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx).

How was REM sleep deprivation induced in the rats?

Using the modified multiple platform method (MMPM) over a six-day period.

Did melatonin have any effect on total oxidant status?

No significant change was observed in total oxidant status (TOS).
