Protective Effect of Selenoprotein X Against Oxidative Stress-Induced Cell Apoptosis in Human Hepatocyte (LO2) Cells via the p38 Pathway.
Abstract Oxidative stress, as mediated by ROS (reactive oxygen species), is a significant factor in initiating the cells damaged by affecting cellular macromolecules and impairing their biological functions; SelX, a selenoprotein also known as MsrB1 belonging to the methionine sulfoxide reductase (Msr) family, is the redox repairing enzyme and involved in redox-related functions. In order to more precisely analyze the relationship between oxidative stress, cell oxidative damage, and SelX, we stably overexpressed porcine Selx full-length cDNA in human normal hepatocyte (LO2) cells.

Hypoglycemic and Hypolipidemic Effects of Leucine, Zinc, and Chromium, Alone and in Combination, in Rats with Type 2 Diabetes.
In conclusion, supplementation of diabetic rats with Leu was more effective in improving blood glucose and consequently decreasing glucose AUC than other nutritional supplements. Supplementary Zn and Cr only improved serum lipid profile. The combination of the nutritional supplements did not improve blood glucose level. Nevertheless, supplementation with Leu-Zn, Leu-Cr, Zn-Cr, and Leu-Zn-Cr led to an improved response in serum lipid profile over each supplement given alone.

We determined the combinatory effects of DHA and ATO on cytotoxicity of human lung adenocarcinoma (A549) cells. We showed that co-exposure to DHA and ATO of A549 cells synergistically increased the cytotoxicity and apoptotic cell death in the cells. We found that the synergistic effect of DHA and ATO in promoting apoptosis mainly resulted from increased cellular level of reactive oxygen species (ROS) and DNA damage. ATO alone only exerted moderate growth inhibitory effec...

Evidence of Zinc in Affording Protection Against X-Ray-Induced Brain Injury in Rats.
Abstract In the present world, X-rays have been regarded as one of the most efficient tools in medicine, industry and research. On the contrary, extensive human exposure to these rays is responsible for causing detrimental effects on physiological system. The aim of the present study was to investigate the role of zinc (Zn), if any, in mitigating the adverse effects induced by fractionated X-irradiation on rat brain. Female Sprague-Dawley rats weighing 170-200 g were divided into four different groups viz.: (a) normal control, (b) X-irradiated (21Gy), (c) zinc treated (227 mg/L in drinking water) and (d)...

Involvement of Zn Depletion in Cd-Induced Toxicity on Prenatal Bone Formation in Rat.
This study explored the potential toxicity of Cd on the Zn bone depletion in prenatal bone formation. Female rats received either tap water, Cd, Zn, or Cd + Zn in their drinking water during gestation, and some markers of bone formation were studied in their fetuses removed at the 20th day of pregnancy (GD20). Cd exposure induced maternal hypozincemia and Zn depletion in the femur of the fetuses. A striking inhibition of bone formation in fetuses, expressed by decreases in femur length, width, and area, by the shortening of diaphysis, and by a decrease in length and area of distal and proximal proliferative zones, was obse...

Effects of Selenium Nanoparticles on Reproductive Performance of Male Sprague-Dawley Rats at Supranutritional and Nonlethal Levels.
Abstract This research investigated the influence of selenium nanoparticles (SeNPs) on the reproductive performance of male Sprague-Dawley (SD) rats. A suspension of SeNPs was consecutively administered by oral gavage for 2 weeks at supranutritional (0.2, 0.4, or 0.8 mg Se/kg bw) and nonlethal (2.0, 4.0, or 8.0 mg Se/kg bw) levels to male SD rats. The normal control (NC) rats were exposed to physiological saline alone. Biochemical parameters, sperm motility, gene expression of GPx1 and GPx4, and histopathological evaluation of male spermary were measured in this work. The supranutritional doses could promote ...

Concentration of Zinc, Copper, Iron, Calcium, and Magnesium in the Serum, Tissues, and Urine of Streptozotocin-Induced Mild Diabetic Rat Model.
, Clapés S Abstract The present study aimed to investigate, in the streptozotocin-induced mild diabetic rat model, the zinc (Zn), copper (Cu), iron (Fe), calcium (Ca), and magnesium (Mg) concentration in serum, liver, and kidney tissues, and urine samples from adult Wistar rats treated neonatally with streptozotocin (STZ). Diabetes was induced by subcutaneous administration of streptozotocin (100 mg/Kg) in female Wistar rats of 2 days old (STZ, n = 10). Control group (CG, n = 10) received only sodium-citrate buffer. The mineral concentrations were measured by atomic absorption ...

Analysis of the Interactions Between Thioredoxin and 20 Selenoproteins in Chicken.
Abstract Thioredoxin (Trx) is a small molecular protein with complicated functions in a number of processes, including inflammation, apoptosis, embryogenesis, cardiovascular disease, and redox regulation. Some selenoproteins, such as glutathione peroxidase (Gpx), iodothyronine deiodinase (Dio), and thioredoxin reductase (TR), are involved in redox regulation. However, whether there are interactions between Trx and selenoproteins is still not known. In the present paper, we used a Modeller, Hex 8.0.0, and the KFC2 Server to predict the interactions between Trx and selenoproteins. We used the Modeller to predict the...

Inactivation of Kupffer Cells by Selenizing Astragalus Polysaccharides Prevents CCl4-Induced Hepatocellular Necrosis in the Male Wistar Rat.
Abstract Selenizing astragalus polysaccharides-3 (sAPS3) was prepared by nitric acid-sodium selenite method. The effects of sAPS3 on carbon tetrachloride (CCl4) induced hepatocellular necrosis, and its underlying mechanisms were studied in male Wistar rats. Hepatic damage was induced by intraperitoneal injection of CCl4 twice a week, for 3 weeks. Meanwhile, the rats in addition to CCl4 were also exposed to sodium selenite (SS), astragalus polysaccharides (APS), SS + APS or sAPS3, in parallel by oral gavage once a day for 3 weeks. At the end of 3 weeks, blood and liver tissue were taken. Serum was co...
