Lipid Peroxides 62-82 glutathione peroxidase 2 Homo sapiens 0-39 10930377-1 2000 BACKGROUND & AIMS: Gastrointestinal glutathione peroxidase (GI-GPx), 1 of the 4 types of selenium-dependent glutathione peroxidases, is expressed exclusively in the gastrointestinal system and has therefore been suggested to function as a barrier against the absorption of dietary hydroperoxides. Adenosine Monophosphate 12-15 glutathione peroxidase 2 Homo sapiens 23-62 10930377-1 2000 BACKGROUND & AIMS: Gastrointestinal glutathione peroxidase (GI-GPx), 1 of the 4 types of selenium-dependent glutathione peroxidases, is expressed exclusively in the gastrointestinal system and has therefore been suggested to function as a barrier against the absorption of dietary hydroperoxides. Adenosine Monophosphate 12-15 glutathione peroxidase 2 Homo sapiens 64-70 10930377-1 2000 BACKGROUND & AIMS: Gastrointestinal glutathione peroxidase (GI-GPx), 1 of the 4 types of selenium-dependent glutathione peroxidases, is expressed exclusively in the gastrointestinal system and has therefore been suggested to function as a barrier against the absorption of dietary hydroperoxides. Selenium 93-101 glutathione peroxidase 2 Homo sapiens 23-62 10930377-1 2000 BACKGROUND & AIMS: Gastrointestinal glutathione peroxidase (GI-GPx), 1 of the 4 types of selenium-dependent glutathione peroxidases, is expressed exclusively in the gastrointestinal system and has therefore been suggested to function as a barrier against the absorption of dietary hydroperoxides. Selenium 93-101 glutathione peroxidase 2 Homo sapiens 64-70 10930377-1 2000 BACKGROUND & AIMS: Gastrointestinal glutathione peroxidase (GI-GPx), 1 of the 4 types of selenium-dependent glutathione peroxidases, is expressed exclusively in the gastrointestinal system and has therefore been suggested to function as a barrier against the absorption of dietary hydroperoxides. Hydrogen Peroxide 285-299 glutathione peroxidase 2 Homo sapiens 23-62 10930377-1 2000 BACKGROUND & AIMS: Gastrointestinal glutathione peroxidase (GI-GPx), 1 of the 4 types of selenium-dependent glutathione peroxidases, is expressed exclusively in the gastrointestinal system and has therefore been suggested to function as a barrier against the absorption of dietary hydroperoxides. Hydrogen Peroxide 285-299 glutathione peroxidase 2 Homo sapiens 64-70 10930377-2 2000 METHODS: The selenium-dependent expression of GI-GPx and cytosolic GPx (cGPx) was analyzed by Western blotting. Selenium 13-21 glutathione peroxidase 2 Homo sapiens 46-52 10930377-3 2000 Transport of 13-hydroperoxy octadecadienoic acid (13-HPODE) was investigated in a CaCo-2 cell monolayer modulated in GI-GPx and cGPx by selenium restriction or repletion. 13-hydroperoxy octadecadienoic acid 13-48 glutathione peroxidase 2 Homo sapiens 117-123 10930377-3 2000 Transport of 13-hydroperoxy octadecadienoic acid (13-HPODE) was investigated in a CaCo-2 cell monolayer modulated in GI-GPx and cGPx by selenium restriction or repletion. 13-Hpode 50-58 glutathione peroxidase 2 Homo sapiens 117-123 10930377-5 2000 RESULTS: Low but significant GI-GPx levels were detected in selenium-deficient CaCo-2 cells and in the gastrointestinal tract of selenium-deficient rats, whereas cGPx was completely absent. Selenium 60-68 glutathione peroxidase 2 Homo sapiens 29-35 10930377-5 2000 RESULTS: Low but significant GI-GPx levels were detected in selenium-deficient CaCo-2 cells and in the gastrointestinal tract of selenium-deficient rats, whereas cGPx was completely absent. Selenium 129-137 glutathione peroxidase 2 Homo sapiens 29-35 10930377-6 2000 Selenium supplementation of CaCo-2 cells resulted in a 5-fold increase of GI-GPx protein, whereas total GPx activity increased by a factor of 13, with most of the GPx activity under selenium-adequate conditions being cGPx. Selenium 0-8 glutathione peroxidase 2 Homo sapiens 74-80 10930377-10 2000 CONCLUSIONS: Low GI-GPx levels, as present in selenium deficiency, suffice to prevent transport of 13-HPODE. Selenium 46-54 glutathione peroxidase 2 Homo sapiens 17-23 10930377-11 2000 GI-GPx may thus function as a barrier against hydroperoxide absorption.
