Effects of GlyNAC on Tissue Regeneration, Behavior, and Locomotor Activity in Dugesia tigrina

Revision as of 02:28, 3 November 2025

Abstract

This study investigates the effects of GlyNAC—a combination of glycine and N-acetylcysteine—on tissue regeneration in Dugesia tigrina (planarians). Aging is associated with physiological decline, including reduced tissue repair and increased oxidative stress. GlyNAC has emerged as a promising anti-aging supplement due to its ability to elevate intracellular glutathione levels, a critical antioxidant that mitigates oxidative damage and supports cellular health. Planarians are used as a model organism in this study due to their robust regenerative capabilities, presence of a central nervous system, and endogenous glutathione production, which parallel key human physiological processes. The experimental design includes one control group fed standard ground beef and three treatment groups fed ground beef supplemented with varying concentrations of GlyNAC. Regenerative capacity will be assessed by measuring the length of planarian regrowth post-amputation. Additionally, motility will be evaluated by recording planarian movement over a 30-minute interval using grid-lined Petri dishes. This study aims to determine whether GlyNAC supplementation enhances tissue regeneration and movement in planarians. Future research should expand the sample size and explore molecular assays to validate findings at a biochemical level.

-<p>This study aims to investigate the effects of GlyNAC on planaria tissue regeneration and behavioral changes. There has been a focus on anti-aging in the older population due to the adverse effects that come with it such as muscle fatigue, a decrease in tissue regeneration, etc. As a result, there was an increase in research on finding an effective supplement to combat health issues and aging. GlyNAC, a combination of Glycine and N-acetylcysteine, has been shown to reverse and improve health by increasing glutathione levels. Glutathione is an antioxidant with multiple health benefits such as protecting against oxidative stress, a main factor in causing cell death. This experiment was conducted using planarians because they have a similar central nervous system, tissue regeneration, and glutathione production to humans. There were 1 control group and 3 experimental groups. The control group was fed regular ground beef while the experimental group was fed ground beef with GlyNAC. For tissue regeneration, each group would be measured and observed before and after the ground beef or GlyNAC-mixed ground beef. The planarians&rsquo; motility was recorded for 20 minutes with grid paper underneath their petri dishes. The results indicate that GlyNAC treated groups had increased regeneration and movement. With this support, our hypothesis of GlyNAC increases the regeneration and movement in planarians. Future Research can be done by having bigger experimental groups for more accurate data. Introduction GlyNAC There has been an interest in anti-aging in the modern day due to one&rsquo;s fear of aging and the many symptoms that come with it, such as muscle fatigue, inflammation, a decrease in tissue</p>
