Summary of article contents:

1) Introduction

The liver serves as a crucial organ for drug metabolism and detoxification, but certain medications, such as sodium valproate (VPA)—an anticonvulsant and mood-stabilizing agent—can induce hepatotoxicity. The incidence of liver injury is notably high among patients undergoing VPA therapy. Moringa oleifera (MO), known for its significant antioxidant properties, has been investigated for its potential protective effects against drug-induced liver damage. This study aimed to assess the hepatoprotective effects of Moringa oleifera leaves extract against sodium valproate-induced liver toxicity in adult rats, focusing on antioxidant activities, biochemical changes, and gene expression related to liver health.

2) Hepatotoxicity Induced by Sodium Valproate

Sodium valproate treatment in rats resulted in a significant increase in liver enzyme activities, such as alanine transaminase (ALT), aspartate transaminase (AST), and gamma-glutamyltransferase (γ-GT), alongside a notable decrease in total protein levels. This biochemical alteration indicates liver damage, which was evident in a time-dependent manner, worsening with the duration of drug exposure. The study highlighted that VPA administration led to increased oxidative stress, as evidenced by elevated malondialdehyde (MDA), oxidized glutathione (GSSG), and nitric oxide (NO) levels, along with a decrease in reduced glutathione (GSH). Collectively, these changes suggest that VPA induces liver injury, primarily through mechanisms involving oxidative stress and apoptosis.

3) The Protective Role of Moringa Oleifera

Moringa oleifera leaves extract demonstrated a significant protective effect against VPA-induced liver damage. The administration of MO resulted in a marked attenuation of liver enzyme activities compared to the VPA-treated group, restoring total protein levels to nearly normal. The extract also reduced levels of inflammatory cytokine TNF-α, indicating an anti-inflammatory effect. Furthermore, MO treatment led to a decrease in oxidative stress levels, with improvements in GSH, GSSG, MDA, and NO concentrations. These findings suggest that the antioxidant properties of Moringa may help neutralize the oxidative damage caused by VPA, thus conferring hepatoprotection.

4) Gene Expression and Apoptotic Signal Modulation

The study also examined the gene expression of pro-apoptotic (Bax) and anti-apoptotic (Bcl2) markers in liver tissues. VPA treatment significantly elevated the expression of Bax while decreasing Bcl2 levels, indicative of an apoptotic response. However, Moringa oleifera was effective in suppressing Bax expression and enhancing Bcl2 levels, thereby signaling a potential protective mechanism against apoptosis in liver cells. This suggests that Moringa not only mitigates oxidative stress but also influences cellular death pathways, adding another layer to its hepatoprotective capacity.

5) Conclusion

The findings of this study indicate that Moringa oleifera leaves extract has significant potential as a hepatoprotective agent against sodium valproate-induced liver toxicity. Through its antioxidant, anti-inflammatory, and anti-apoptotic properties, Moringa effectively mitigates the adverse biochemical and histopathological effects of VPA on liver function. Therefore, incorporating Moringa oleifera into treatment regimens may provide a therapeutic strategy to safeguard liver health in patients undergoing sodium valproate therapy, emphasizing the importance of exploring natural compounds for hepatoprotection.
