However, Al is known to be associated with various neurodegenerative diseases. Taurine is a free amino acid presents at high concentrations in the brain and is crucial for neuron development. Here, the protective effects of taurine against Al-induced neurotoxicity were investigated. Al, at a concentration of 600 mu M, induced apoptosis of and cell cycle arrest in human neuroblastoma SH-SY5Y cells. Additionally, Al induced a 55% increase in the levels of reactive oxygen species and inhibited mitochondria' membrane potential up to 60%. Al treatment also stimulated caspase 9 activities and Grp78 production. Furthermore, the expressions of neurotrophic genes including NDRG-4, BDNF and SIRT1 were inhibited. Hence this study revealed that taurine attenuates oxidative stress, ER stress and mitochondrial dysfunction and consequently protects against Al-induced cytotoxicity and neuronal apoptosis. |
