| dietary selenite and azadeoxycytidine treatments affect dimethylhydrazine-induced aberrant crypt formation in rat colon and dna methylation in ht-29 cells. | several observations implicate a role for altered dna methylation in cancer pathogenesis. the global level of dna methylation is generally lower; however, dna methyltransferase (dnmt1) activity is usually higher in tumor cells than in normal cells. the purpose of this study was to investigate whether the dnmt1 inhibitor, 5-aza-2'-deoxycytidine (aza-dc) would alter the effect of dietary selenium on the formation of aberrant crypts. weanling rats (n = 60) were fed three concentrations of selenium ... | 2002 | 11823593 |
| in vitro function of s rnases in lycopersicon peruvianum. | s rnases are products of the s locus that are expressed in the stylar tissue of lycopersicon peruvianum with the gametophytic self-incompatibility (si) system. two s rnases (s12 and sa) with rnase activity from the s12sa genotype of l. peruvianum were purified using gel filtration and cation-exchange chromatography. the molecular masses of the two rnases, s12 and sa, were 21 and 23.1 kda, respectively. the specific activities of s12 and sa for torula yeast rrna as a substrate were 8,500 and 6,00 ... | 2001 | 11804331 |
| gene expression profiling of low selenium status in the mouse intestine: transcriptional activation of genes linked to dna damage, cell cycle control and oxidative stress. | the essential trace mineral selenium (se) has been shown previously to inhibit intestinal, prostate, lung and liver tumor development and associated mortality in both experimental animals and humans. although se is likely to be one of the most powerful cancer chemopreventive agents in the human diet, its mechanism of action is unknown. to better understand the biological consequences of alterations in se status, the gene expression profile associated with low se status in the intestine of c57bl/ ... | 2001 | 11739862 |
| selenium from selenium-rich spirulina is less bioavailable than selenium from sodium selenite and selenomethionine in selenium-deficient rats. | the bioavailabilty of selenium (se) from selenium-rich spirulina (sesp) was assessed in se-deficient rats by measuring tissue se accumulation and glutathione peroxidase (gsh-px) activity. for 42 d, rats were subjected to dietary se depletion by consumption of a torula yeast (ty)-based diet with no se; controls were fed the same diet supplemented with 75 microg se/kg diet as sodium selenite. se-deficient rats were then repleted with se (75 microg/kg) by the addition of sodium selenite, selenometh ... | 2001 | 11533277 |
| promotion of lipid oxidation by selenate and selenite and indicators of lipid peroxidation in the rat. | the ain-93 reformulation of the ain-76a rodent diet includes a change in selenium supplement from sodium selenite to sodium selenate to reduce dietary lipid peroxidation. a change to selenate as the standard form of se in rat diets would render results from previous work using selenite less relevant for comparison with studies using the ain-93 formulation. to critically examine the rationale for the ain-93 recommendation, we prepared torula yeast basal diets patterned as closely as possible afte ... | 2001 | 11354350 |
| dietary selenium and arsenic affect dna methylation in vitro in caco-2 cells and in vivo in rat liver and colon. | selenium is an essential trace element for human health, and it has received considerable attention for its possible role as an anticarcinogenic agent. the purpose of the present study was to determine whether changes in the amount and the chemical form of selenium would affect dna methylation and whether this effect would be modified by arsenic. caco-2 cells, a human colon cancer cell line, were exposed to 0, 1 or 2 micromol supplemental selenite/l and 0, 1 or 2 micromol supplemental arsenite/l ... | 2000 | 11110844 |

| cellular glutathione peroxidase knockout mice express normal levels of selenium-dependent plasma and phospholipid hydroperoxide glutathione peroxidases in various tissues. | selenium-dependent cellular glutathione peroxidase (gpx1) knockout [gpx1(-)] mice were derived from 129/svj x c57bl/6 hybrid mice by microinjecting c57bl/6 blastocysts with recombinant embryonic stem cells carrying a target mutation in the gpx1 gene. experiment 1 was conducted to determine the effects of the gpx1 knockout on the susceptibility of mice to dietary vitamin e and se deficiency and on the expression of the se-dependent plasma glutathione peroxidase (gpx3) and phospholipid hydroperoxi ... | 1997 | 9237936 |
| influence of dietary selenium on the disposition of arsenate in the female b6c3f1 mouse. | interactions between arsenic (as) and selenium (se) at the metabolic level are multifaceted and complex. these interactions are of practical significance because populations in various parts of the world are simultaneously exposed to inorganic as in drinking water and se mainly in the diet at varying levels. the primary goal of this study was to investigate whether differing dietary se status would alter the profile of urinary metabolites or their time course for elimination after exposure to ar ... | 1997 | 9183383 |
