Lutein and zeaxanthin reduce neuronal cell damage caused by lipid peroxidation
Oxidative stress and lipid peroxide levels in the brain increase with aging. The carotenoids lutein and zeaxanthin have potent antioxidant properties and the ability to improve cognitive function. However, their effects on neuronal damage via lipid peroxidation remain unknown. Therefore, we aimed to elucidate the effects of these carotenoids on neuronal damage induced by accumulated peroxidized lipids. We developed an oxidative stress model of lipid peroxidation-induced neuronal damage using differentiated neuronal cells derived from human neuroblastoma SH-SY5Y cells in vitro. Combining rotenone and RSL3 increased mitochondrial oxidative stress and lipid reactive oxygen species (ROS), which resulted in enhanced neuronal damage. Lutein and zeaxanthin were added to the cells for 1 week, and these carotenoids suppressed mitochondrial oxidative stress and lipid peroxidation in differentiated neuronal cells and mitigated neuronal damage. Further investigation is required to clarify the underlying pathways in detail.
期刊介绍:
Open access, online only, peer-reviewed international journal in the Life Sciences, established in 2014 Biochemistry and Biophysics Reports (BB Reports) publishes original research in all aspects of Biochemistry, Biophysics and related areas like Molecular and Cell Biology. BB Reports welcomes solid though more preliminary, descriptive and small scale results if they have the potential to stimulate and/or contribute to future research, leading to new insights or hypothesis. Primary criteria for acceptance is that the work is original, scientifically and technically sound and provides valuable knowledge to life sciences research. We strongly believe all results deserve to be published and documented for the advancement of science. BB Reports specifically appreciates receiving reports on: Negative results, Replication studies, Reanalysis of previous datasets.
