Impact of maternal diet supplemented with selenium (Se) and vitamin B6 during pregnancy on gene expression of porcine expanded blastocysts (EB)

ABSTRACT: Transcriptional profiling of porcine expanded blastocysts comparing control (EB obtained from 4 sows treated with basal diet) with either inorganic Se + B6 (EB obtained from 4 sows treated with basal diet plus inorganic Se and B6) or organic Se + B6 (EB obtained from 3 sows treated with basal diet plus organic Se and B6). Three-condition experiment, EB without and with maternal diet supplemented B6 plus either inorganic Se or organic Se. Four biological replicates for inorganic Se and three biological replicates and one technical replicate for organic Se. Pooled of four biological replicates for control group.

Effect of Dietary Supplementation of Selenium (Organic vs. Inorganic) on Liver Gene Expression Profile in Beef Heifers

Project description:Selenium (Se) is an essential nutrient for beef cattle health and commercial production. The molecular mechanisms responsible for physiological responses of the animal to dietary Se supplementation, however, have not been evaluated. Furthermore, the potential effect of two chemical forms (organic vs. inorganic) of Se on gene expression by Se-sufficient cattle has not been evaluated. Microarray analysis using the GeneChip Bovine Genome Array (Affymetrix, Inc., Santa Clara, CA) was conducted to determine if dietary Se supplementation in organic vs. inorganic form (OSe vs. ISe) differentially affects the liver gene expression profile in growing beef heifers. Sodium selenite (Prince Se Concentrate; Prince Agri Products, Inc., Quincy, IL) was used as the source of ISe form. Se-enriched yeast (Sel-Plex; Alltech, Inc., Nicholasville, KY) was used as the source of OSe form. Thirty Angus heifers (BW 393 Â± 9 kg) were randomly assigned to 3 dietary treatments (n = 10): Control (Ctrl) group received no dietary Se supplementation; ISe treatment group daily received dietary supplementation of Se at 3 mg/animal from ISe source; OSe treatment group daily received dietary supplementation of Se at 3 mg/animal from OSe source. Six animals were randomly selected from each of 3 treatment groups for RNA extraction and microarray analysis.

Gene expression in broiler livers upon supplementation with selenized yeast

Project description:Selenium (Se) is an essential cofactor of the antioxidant enzyme glutathione peroxidase beside other functions. The evaluation of optimal selenium supplementation in chicken feed and the subsequent effects on animal health and performance requires comprehensive knowledge of the overall metabolic effects of selenium. Therefore the gene expression was measured in the control group with a standard diet and in the group with a Se supplemented diet (0.5mg Se/kg diet) to determine significantly altered gene expression. The selenium was supplemented in the form of selenized yeast (Se-yeast), which mainly consists of organic Se in the form of L-selenomethionine and L-selenocysteine. The control group received a diet, which contained 70μg of Se / kg diet and the Se-yeast group 620μg of Se / kg diet (analyzed). The one-day old broiler chicks were separated into two groups and received the control or the Se-supplemented diet ad libitum for 35 days. After slaughter the gene expression was determined in the liver of four control and five samples from the Se-yeast group. One sample from the control group did not correspond to the quality requirements and was excluded from the analysis.

Hepatic transcriptome profiles differ among maturing beef heifers supplemented with different forms of dietary selenium

Project description:Little is known regarding the relationship between Selenium (Se) concentrations in the liver and liver gene expression. Because most cow-calf operations in Se-poor soils provide enough Se in mineral mixes to avoid deficiency, the aim of this study was to determine the effects of 4 Se form supplementation strategies (none or inorganic, organic, or 1:1 inorganic:organic mix) on liver gene expression profiles using a Se-adequate model. Microarray analysis was conducted using the custom WT Btau 4.0 Array (version 1; GeneChip, Affymetrix, Inc., Santa Clara, CA, USA) to determine if dietary Se supplementation form differentially affects the hepatic gene expression profiles of maturing beef heifers. Sodium selenite was used as the source of inorganic Se and Se-enriched yeast was the source of organic selenium. Thirty-six Angus heifers (BW 400 Â± 9.0 kg) were ranked on the Se concentration of their biopsied (day -14) liver sample and randomly assigned to one of four dietary Se treatments: Control (Ctrl) group received no exogenous dietary Se supplementation; inorganic (ISe) treatment group received daily dietary Se supplementation at 3 mg/ animal of the ISe form; organic (OSe) treatment group received daily dietary Se supplementation of 3 mg/ animal of OSe form; and the mix (1:1 ISe:OSe) received daily dietary Se supplementation of 3 mg/ animal of 50:50 mix of ISe and OSe forms. RNA was extracted from biopsied liver samples taken 168 days after initiation of Se supplementation and microarray analyses were conducted.

Neonatal testis transcriptome profiles differ among calves born to cows supplemented with different forms of dietary selenium throughout gestation

Project description:In many parts of the US, selenium (Se)-deficient soils dictate the necessity of supplementing this trace mineral directly to the diet of cattle, with the form of Se supplied known to affect tissue-level gene expression profiles and presumably function. Because a deficiency of Se will reduce fertility, including reduced biosynthesis of testosterone by the testis and an increased frequency of abnormalities in mature spermatozoa, we hypothesized that the form of Se supplemented to cows during gestation would affect the transcriptome of the neonatal bull calf testis. Microarray analysis using the Bovine gene 1.0 ST array (GeneChip; Affymetrix, Inc., Santa Clara, CA) was conducted to determine whether gestational form of supplemental Se affected gene expression profiles in the testis. GeneChip transcript annotations were last updated in January 2013 using the annotation update release 33 from the NetAffx annotation database. Twenty-four Angus cross cows were assigned randomly (n=8) to individual ad libitum intake of a common vitamin-mineral mix that contained 35 ppm of Se supplied as either inorganic (ISe, sodium selenite; Prince Se Concentrate, Prince Agri Products, Inc., Quincy, IL), organic (OSe, Sel-Plex; Alltech Inc., Nicholasville, KY), or a 50/50 mix of ISe/OSe (Mix) Se for 4 months prior to breeding and throughout gestation. Cows were managed under a fall-calving, forage-based, cow-calf production regimen at the University of Kentucky Princeton Research and Education Center. Testis tissue (ISe n=5; OSe n=4; Mix n=4) was collected within 2 days of birth, and RNA extracted for microarray analysis.

Intermittent suckling does not influence the gene expression of Day 9 embryos during early gestation in primiparous sows

Project description:Primiparous sows were randomly allocated to two treatments and were separated from piglets 8h daily from Day 21 of lactation companied with daily boar exposure for oestrus detection until weaning (Day 28). Gene expression of Day 9 embryos were compared between control sows (FE; sows artificially inseminated when in heat during lactation ) and Skip-a-Heat sows (SE; sows in heat during lactation and artificially inseminated on the following oestrus cycle). Stimulating lactational oestrus then two mating strategies were applied to primiparous sows; 1)FE; sows were in heat during lactation and received artificial insemination) and Skip-a-Heat sows (SE; sows were in heat during lactation and received artificial insemination at fallowing oestrus cycle).

Proteomic changes associated with maternal dietary low ω6:ω3 ratio in piglets supplemented with seaweed Part I: Serum proteomes

Project description:This study examines whether maternal low ω6:ω3 ratio diet and offspring seaweed (SW) supplementation can improve offspring immunity and performance by elucidating the effects on piglet serum proteome. A total of 16 sows were given either a standard (CR, 13:1) or low ω6:ω3 ratio diet (LR, 4:1) during pregnancy and lactation and their male weaned piglets were supplemented with SW powder (4 g/kg, SW) or not (CT) in a 21-day post-weaning (PW) diet. Four PW piglet groups were then identified based on dam and piglet treatment, namely CRCT, CRSW, LRCT, and LRSW (n = 10 each). Piglet serum collected at weaning and d21 PW were analyzed (n = 5 each) using TMT-based quantitative proteomics and validated by appropriate assays.
