Metabolomics1H NMR metabolomic and transcriptomic analyses reveal urinary metabolites as biomarker candidates in response to protein undernutrition in adult rats

BACKGROUND: Protein undernutrition is prevalent mainly among elderly people, and it could develop diseases such as sarcopenia. Urinary metabolites may become biomarkers reflecting protein undernutrition, but this has been insufficiently investigated.

MetabolomicsComprehensive systems biology analysis of a seven-month cigarette smoke inhalation study in C57BL/6 mice
Smoking of combustible cigarettes has a major impact on human health. Using a systems toxicology approach in a model of chronic obstructive pulmonary disease (C57BL/6 mice), we assessed the health consequences in mice of smoke derived from a prototype modified risk tobacco product (pMRTP) as compare...

TranscriptomicsPRONOUNCED PHENOTYPE IN ACTIVATED TREG CELLS DURING A CHRONIC HELMINTH INFECTION
Although several markers have been associated with the characterization of regulatory T cells (Treg) and their function, no studies have investigated the dynamics of their phenotype during infection. Since the necessity of Treg to control immunopathology has been demonstrated, we used the chronic he...

TranscriptomicsAn ABA response regulator unique to basal land plants required for the acquisition of desiccation tolerance
Purpose: The plant hormone abscisic acid (ABA) coordinates responses leading to desiccation tolerance in all land plants. RNA-seq was employed to obtain differential expression data in response to ABA, dehydration and mannitol treatments in wild-type tissue. This was compared against the targeted ge...

TranscriptomicsThe unfolded protein response in fission yeast modulates stability of select mRNAs to maintain protein homeostasis
Homeostatic control mechanisms are essentil to life. One such mechanism, the unfolded protein response (UPR) operates in all eukarytic cells to adjust protein folding capacity of the endoplasmic reticulum (ER) according to need. UPR induction in all eurkarytic cells to date involves Ire1 (kinase/end...

TranscriptomicsTranscription profiling of spleens from dual specificity phosphatase-1 (DUSP1) deficient and wild type mice to demonstrate a specific regulatory role of DUSP1 on a subset of LPS-induced genes that control the outcome of endotoxin shock.
Activation of the Mitogen activated protein kinase (MAPK) cascade following Toll-like receptor (TLR) stimulation enables innate immune cells to rapidly activate cytokine gene expression. A balanced response to signals of infectious danger requires that cellular activation is transient. Here, we iden...

TranscriptomicsRNAseq of S. meliloti Rm1021 all ecf/anti-σ deletion mutants overexpressing heterologous ecf genes compared to an empty vector control strain
Bacterial σ factors are dissociable subunits of the core RNA polymerase and important for promoter recognition and transcription initiation. Extracytoplasmic function (ECF) σ factors (σs) represent the most minimalistic and diverse group of alternative σs within the σ70 protein family. It has been s...

TranscriptomicsIdentification of RpoE2 target genes in Sinorhizobium meliloti
Sinorhizobium meliloti lives as a soil saprophyte, and engages in a nitrogen fixing symbiosis with plant roots. To succeed in such diverse environments, the bacteria must continually adjust gene expression. Transcriptional plasticity in eubacteria is often mediated by alternative sigma factors int...

MetabolomicsIn Vitro and In Vivo Metabolomic Profiling after Infection with Virulent Newcastle Disease Virus
Newcastle disease (ND) is an acute, febrile, and highly contagious disease caused by the virulent Newcastle disease virus (vNDV) worldwide. The disease causes serious economic losses to the poultry industry. However, the metabolic changes caused by vNDV infection remain unclear. The objective of thi...

TranscriptomicsTranscription profiling by array of human stromal cells cultured with or without 3D BPH-1 prostate epithelial cells
BPH-1 prostate epithelial cells when cultured in Matrigel form 3D acini which closely recapitulate the tissue architecture of the prostate. The presence of primary stroma increases epithelial adhesions and causes changes in morphology. To identify the stromal signals which control actin/cadherin dy...
