Preventive Effect of Astaxanthin on Diabetic Cataracts and Its Protective Effect on Lens Epithelial Cells

Abstract

To better combat the development of diabetic cataracts (DC), we conducted a study on the use of astaxanthin (ATX) as an innovative antioxidant. Our research found that ATX exhibited good biocompatibility with lens epithelial cells (LECs) and increasing its concentration did not reduce cell activity. In the presence of high glucose, LECs experienced elevated oxidative stress levels, leading to a significant inhibition of their activity. However, the addition of ATX increased the antioxidant levels in LECs, resulting in a concentration-dependent increase in cell activity. Furthermore, when tested on diabetic rat models, higher concentrations of ATX application effectively prevented the development of DC and suppressed the level of oxidative stress in the lens. Our findings highlight the strong antioxidant effect of ATX, which can safeguard LEC activity in the presence of high glucose and inhibit the development of DC.
