Abstract
INTRODUCTION
Multiple sclerosis (MS) is a complex central nervous system disorder, marked by neurodegenerative and inflammatory processes, where overproduction of reactive oxygen species (ROS) is a key factor in demyelination and neurodegeneration. The current study aims to investigate the effect of hesperidin and Quinolinic acid (QA) on ROS and antioxidant levels, and cell viability of OLN-93 cells.
METHODS
OLN-93 cell lines were treated with hesperidin and QA. OLN-93 cells were cultured in Dulbecco's modified Eagle's medium under controlled conditions. Cell viability assays were performed using resazurin to assess the toxicity of hesperidin and QA. Additionally, ROS levels were measured using DCFDA, and malondialdehyde (MDA) levels were determined to evaluate oxidative stress. Superoxide dismutase (SOD) activity and cell viability were assessed by trypan blue staining after exposure to hesperidin and QA.
RESULTS
The results of the current study showed that co-administration of 8 mM QA with 50, 100, and 200 μM hesperidin significantly reduced both ROS and MDA levels, demonstrating a substantial attenuation in comparison to the elevated ROS and MDA levels induced by 8 mM QA (p-value < 0.01). Furthermore, 8 mM QA + 50, 100, and 200 μM hesperidin significantly increased SOD levels compared with QA alone (p-value < 0.01). In addition, treatment of OLN cells with 8 mM QA + 50, 100, and 200 μM hesperidin led to higher cell viability compared to QA alone (p value <0.0001).
CONCLUSION
The current study demonstrated the antioxidant effect of hesperidin on OLN-93 cells suggesting new insights into the clinical application of hesperidin as an effective treatment for patients with MS. Future in vivo studies, focusing on cellular mechanisms are recommended.
