    Sammanfattning : Selenium (Se) is an essential trace element that is involved in several physiological functions in mammals. Mostly, Se is bound to proteins, many of them with enzymatic functions. A group of seleno-depending enzymes, glutathione peroxidases (GSH-Px’s), are important as antioxidants and protects against free radicals. LÄS MER

    Sammanfattning :   The Thioredoxin (Trx) and Glutaredoxin (Grx) system are two major antioxidant redoxsystems in the cells that prevent and respond to oxidative stress, which is a well known factor in aging and causing several diseases, like neurodegenerative disorders, diabetes and cancer. Oxidative stress also can be described as an imbalance between production of reactive oxygen species (ROS) and the cellular protection. LÄS MER
