Nutrient sensing controlling gut motility in the stomachless fish ballan wrasse (Labrus berggylta)

ABSTRACT: Ex vivo intestines from 15-20 g ballan wrass (Labrus bergylta) were administered a bolus (lipid, protein, inert matter or empty control) before being mounted in oxygenated physiological buffer inside a glass vial. The intestinal motility patterns were documented with time lapse imaging for 14 hours. The images were used to construct spatio-temporal maps for gut motility analysis; i.e. to determine the speed, amplitude, frequency, travelled distance, direction, and initiation site of waves of muscle contractions. The experiments were repeated for RNA sampling and deep seq analysis. Gene expression analysis showed that intestines administered intact lipids clustered closer to the empty intestines compared to those given hydrolyzed lipids.

Responses to DNA vaccine against H5 virus in spleens of Rosa 1 chickens

Project description:Laying hens Rosa 1 were immunized with two doses of DNA vaccine, based on the hemagglutinin (HA) DNA from H5N1 virus, in comparison to the control group, which was administered an empty vector (pCI). Additional groups of Rosa 1 hens were treated with one dose of above described vaccine or empty vector. Gene expression changes in the spleens of chickens were investigated at 7 day post last vaccination dose.

Modification of miRNA profile in Caco-2 cells by dietary lipids

Project description:The aim of this study was to detect miRNAs modified by biactive dietary lipids in a cellular model of enterocytes. The selected model was Caco-2 cells Differentiated Caco-2 cells were incubated with micelles containing the lipids for 24 and 48 hours. The expression leveles of the miRNAs were compared with cells treated with empty micelles. Four control and choelsterol samples, three DHA samples and two CLA samples were analyzed variables: Control (Empty micelles), Cholesterol 250 M-BM-5M 48h, DHA 200 M-BM-5M 24h, CLA 200M-BM-5M 24h Biological replicates Control: Samples 137, 159, 160, 210 Cholesterol: Samples 150, 151, 152, 219 DHA: Samples 141, 142, 143 CLA: Samples 144, 146

Transcriptional response to a prime/boost vaccination of chickens with three vaccine variants based on HA DNA and Pichia-produced HA protein

Project description:Broilers were immunized with three variants of subunit vaccines, based on the hemagglutinin (HA) DNA and Pichia-produced HA protein from H5N1 virus, in comparison to the control group, which was administered an empty vector (pCI). Gene expression changes in the spleens of chickens were investigated at 7 day post booster dose.

CEBPD suppresses motility-associated gene signatures and reduces pancreatic ductal adenocarcinoma cell migration

Project description:To investigate the effects of CEBPD on pancreatic ductal cell tumorigenicity, we established doxycycline-inducible MIA PaCa-2 cells for CEBPD over-expression, as well as non-control cells with an empty inducible construct. RNAseq was performed on these cells in the presence and absence of doxycycline and we showed that CEBPD activates gene signatures associated with cell motility.

Transcriptome responses to dexamethasone of the hypothalamus of pigs with different genotypes at the GRAla610Val mutation

Project description:The main aims of the experiment were to 1) chart gene networks governed by glucocorticoid receptor on a genome-wide scale, 2) to provide insights into mechanisms modulating glucocorticoid sensitivity and 3) to obtain better understanding of molecular and phenotypic consequences of the GRAla610Val substitution by examining its transcriptome signature in untreated and dexamethasone-treated animals. A total of 48 purebred German Landrace piglets were used in the experiment. At the time of the experiment the piglets were 7-weeks old. A bolus injection of either dexamethasone or sterile saline was administered intramuscularly into the neck muscle. Twenty piglets received saline, sixteen piglets were treated with 10 μg/kg dexamethasone, and twelve piglets were treated with 60 μg/kg dexamethasone. All three treatment groups were balanced for sex and genotype.

Muscle directs diurnal energy homeostasis through a myokine-dependent hormone module in Drosophila

Project description:Inter-tissue communication is critical to control organismal energy homeostasis in response to temporal changes in feeding and activity or external challenges. Muscle is emerging as a key mediator of this homeostatic control through consumption of lipids, carbohydrates, and amino acids, as well as governing systemic signaling networks. However, it remains less clear how energy substrate usage tissues, such as muscle, communicate with energy substrate storage tissues in order to adapt with diurnal changes in energy supply and demand. Using Drosophila, we show here that muscle plays a crucial physiological role in promoting systemic synthesis and accumulation of lipids in fat storage tissues through Foxo. To gain more insight into these tissue-specific changes in lipid metabolism, we generated genome-wide expression profiles from dissected thoraces (enriched in indirect flight muscle), carcass (enriched in fat body), and intestines of Act88FG4>FoxoRNAi flies and control animals.
