Astaxanthin Prevents Oxidative Damage and Cell Apoptosis Under Oxidative Stress Involving the Restoration of Mitochondrial Function

Year: 2024

Type: article

Abstract: ABSTRACT Oxidative stress (OS) is one of the factors that result in cell damage and the development of neurological diseases such as Alzheimer's disease (AD). Astaxanthin (ASTA), a natural compound known for its potent antioxidant properties, shows the biological activities in anti‐apoptosis and antitumor. However, its specific mechanism on mitochondrial function remains unclear. This study investigated the effects of ASTA on regulation in mitochondrial function and cell apoptosis under OS induced by hydrogen peroxide (H2O2). The results demonstrated that ASTA (0.1, 1, 10 μmol/L) protected cells form H2O2‐induced cell damage and apoptosis through mitochondrial pathway. ASTA significantly reduced H2O2‐induced mitochondrial dysfunctions and restored the intracellular reactive oxygen species (ROS), mitochondrial membrane potential, and respiratory capacity. These findings suggest that ASTA's antioxidant properties can benefit neurons by maintaining mitochondrial function and alleviating oxidative damage and cell apoptosis induced by H2O2.
