MetabolomicsL-Citrulline and L-arginine regulate the reproductive performance of young and adult cows through distinct metabolic pathways and the shared pyrimidine metabolic pathway respectively

(Background)To investigate the impact of L-arginine (L-Arg) and L-citrulline (L-Cit) on cow reproductive performance.(Methods) 90 healthy, age-matched Simmental cows were randomly assigned to three groups: control, L-Arg, and L-Cit, with 30 cows per group. Estrus synchronization was performed, an...

MetabolomicsThe effects of oligomycin administration and glutamine deprivation on metabolic profile of MCF7 breast cancer cell line measured using [1,2-13C2]-D-glucose and [U-13C5]-L-glutamine as tracers
This study aims to establish a comprehensive, genome-scale metabolic model (GSMM) combining different omics data of different regulatory levels of breast cancer cells in order to elucidate the way that these regulatory levels affect or determine each other. Together with transcriptomics, proteomics ...

TranscriptomicsIdentification of genes regulated by L-lactate and by DL-lactate in Lactobacillus plantarum
L. plantarum is known to possess an L-lactate inducible lactate racemase activity (Goffin et al. 2005. J. Bacteriol. 187:6750). In the present study, microarrays were used in order to identify all genes that are up-regulated by L-lactate, but not by a racemic mixture of D- and L-lactate. A mutant of...

GenomicsGenome wide map of long noncoding RNA Tug1 binding sites in cultured mouse podocytes
We generated a genome wide map of instances where the long noncoding RNA, Tug1, binds to DNA in cultured mouse podocytes under normal glucose conditions using Chromatin-RNA Precipitation coupled with high throughput sequencing (ChIRP-Seq) 48 alternating (even, odd) biotynilated probes were designed ...

TranscriptomicsTranscription profiling of yeast under conditions of ammonium, L-alanine or L-glutamine limitation
Response of Saccharomyces cerevisiae to Ammonium, L-alanine, or L-glutamine Limitation. The protrotophic laboratory strain CEN.PK113-7D (MAT a) was grown in laboratory fermentors with a working volume of 1 litre at dilution rate (D) of 0.20 per hour (in triplicate for each nitrogen limited condition...

MetabolomicsDeletion of glycerol channel aquaporin-9 (Aqp9) impairs long-term blood glucose control in C57BL/6 leptin receptor-deficient (db/db) obese mice
Deletion of the glycerol channel aquaporin-9 (Aqp9) reduces postprandial blood glucose levels in leptin receptor deficient (db/db) obese mice on a C57BL/6×C57BLKS mixed genetic background. Furthermore, shRNA mediated reduction of Aqp9 expression reduces liver triacylglycerol (TAG) accumulation in a ...

TranscriptomicsImproved transcription and translation with L-leucine stimulation of mTORC1
Roberts syndrome (RBS) is a human developmental disorder caused by mutations in the cohesin acetyltransferase ESCO2. We previously reported that mTORC1 was inhibited and overall translation was reduced in RBS cells. Treatment of RBS cells with L-leucine partially rescued mTOR function and protein sy...

TranscriptomicsA Short-Term Study Investigating the Estrogenic Potency of Diethylstilbesterol in the Fathead Minnow (Pimephales promelas): Exposure Phase
Diethylstilbestrol (DES) is a synthetic estrogen that has been banned for use in humans, but still is employed in livestock and aquaculture operations in some parts of the world. Detectable concentrations of DES in effluent and surface waters have been reported to range from slightly below 1 to gre...

TranscriptomicsD-Glutamate Utilization in Pseudomonas aeruginosa PAO1
D-Glutamate (D-Glu), an essential component of peptidoglycans, can be utilized as carbon and nitrogen source by Pseudomonas aeruginosa. DNA microarrays were employed to identify genes involved in D-Glu catabolism. Through gene knockout and growth phenotype analysis, the divergent dguR-dguABC (D-glut...

TranscriptomicsDifferential expression of Dictyostelium discoideum AX2 upon infection with wt L. pneumophila JR32 vs. the L. pneumophila delta DotA mutant 24h p.i.
Differential gene expression of Dictyostelium discoideum after infection with Legionella pneumophila was investigated using DNA microarrays. A detailed analysis of the 24 h time point post infection was performed in comparison to three controls, uninfected cells and co-incubation with Legionella hac...
