1. Selenium Compounds in Milk. Studies of Selenoproteins, Selenium Enrichment and Oxidative Stability of Food
Abstract : Selenium is an essential nutrient and in animals and humans it can either be specifically incorporated into proteins as selenocysteine or randomly as selenomethionine. It can also occur as low-molecular-weight compounds and the form of selenium in foods may also influence food quality. READ MORE

2. Selenoproteins in the Bovine Mammary Gland. Regulation of mRNA and Protein Expression
Abstract : Selenium is a micronutrient that is essential for many important life processes due to the action of the specific selenoproteins containing one or more of the 21st amino acid, selenocysteine. Twenty-five selenoprotein genes have been found in the human genome but the function of many of them is not yet known. READ MORE

3. Mammalian thioredoxin reductase as a drug target in anticancer therapy through direct apoptosis induction by selenium compromised forms of the protein
Abstract : The mammalian thioredoxin system, consisting of thioredoxin(s), thioredoxin reductase(s) and NADPH, participates in the regulation of many important systems in a mammalian cell. The mammalian thioredoxin reductases (TrxR) are selenoproteins containing a selenocysteine (Sec) residue within a carboxyl terminal -Gly -Cys -Sec -Gly -COOH motif. READ MORE

4. Selenocysteine in proteins : properties and biotechnological use
Abstract : Selenocysteine (Sec), the 21st amino acid, exists in all kingdoms of life and has unique biochemical properties, such as high electrophilicity and low pKa. The highly increased reactivity of selenoenzymes compared to their sulfur-containing cysteine-dependent homologs is generally regarded as the evolutionary reason for having selenoproteins. READ MORE

5. Selenium cytotoxicity in cancer
Abstract : Selenium is an essential trace element, present in the 21st amino acid selenocysteine, which is specifically incorporated into selenoproteins. Today, there are 25 identified selenoproteins in humans, whereof many comprises redox active functions to uphold the intracellular redox balance. READ MORE
