Project description:Gebauer2016 - Genome-scale model of
Caenorhabditis elegans metabolism (with bacteria)
This model is one of the two versions
of ElegCyc presented in the paper. It describes the metabolism of a
worm raised in a medium with bacteria
This model is described in the article:
A Genome-Scale Database and
Reconstruction of Caenorhabditis elegans Metabolism.

Abstract:
We present a genome-scale model of Caenorhabditis elegans
metabolism along with the public database ElegCyc
(http://elegcyc.bioinf.uni-jena.de:1100), which represents a
reference for metabolic pathways in the worm and allows for the
visualization as well as analysis of omics datasets.
Our model reflects the metabolic peculiarities of
C. elegans that make it distinct from other higher
eukaryotes and mammals, including mice and humans. We
experimentally verify one of these peculiarities by showing
that the lifespan-extending effect of L-tryptophan
supplementation is dose dependent (hormetic). Finally, we show
the utility of our model for analyzing omics datasets through
predicting changes in amino acid concentrations after genetic
perturbations and analyzing metabolic changes during normal
aging as well as during two distinct, reactive oxygen
species (ROS)-related lifespan-extending treatments. Our
analyses reveal a notable similarity in metabolic adaptation
between distinct lifespan-extending interventions and point to
key pathways affecting lifespan in nematodes.

Project description:We sought to study the effect of heat stress on gene expression in C. elegans. We cultured CF512 animals to adulthood at 25C (at which they are sterile). We then induced heat stress by switching the culture temperature to 30C. Keywords: time-course

Project description:This explorative study investigated the transcriptional response of C. elegans wild types N2 and CB4856 after Orsay virus infection and Heat shock (n=1). Each strain had a sample that was heat-shocked and infected, one that was heat-shocked and mock-infected, one that was only infected and one that only underwent a mock infection. Age synchronized worms were treated separately according to different treatments mentioned before. After flash freezing, RNA was isolated, labeled and hybridized on oligo microarray (Agilent) slides.

Project description:PMK-1 is involved in the heat stress response of C. elegans, translocates to the nucleus upon heat exposure and influences the expression of chaperone genes, proteasomal subunits and protein-biosynthesis related genes.

Project description:Physiological interaction partners of the small heat shock protein HSP-17 from C. elegans were to be identified in the context of a study on the function of this non-canonical small heat shock protein in vivo and in vitro. An immunoprecipitation with an antibody raised against HSP-17 was performed on lysates of wild type C. elegans, followed by MS analysis.

Project description:N2 young adult animals were analyzed four hours after exposure to wild-type Candida albicans DAY185, heat-killed C. albicans DAY185 and heat-killed Escherichia coli OP50, all on Brain Heart Infusion (BHI) agar. It was necessary to use heat-killed E. coli OP50 as a control for these experiments because live E. coli OP50 (the normal nematode food source) is pathogenic to nematodes on BHI agar. These data identify the C. elegans genes that are differentially regulated during nematode infection with a human fungal pathogen.

Project description:Young adult N2 Caenorhabditis elegans were infected with Enterococcus faecalis or Enterococcus faecium for 8 h to determine the transcriptional host response to each enterococcal species. Analysis of differential gene expression in C. elegans young adults exposed to four different bacteria: heat-killed Escherichia coli strain OP50 (control), wild-type E. faecalis MMH594, wild-type E. faecium E007, or Bacillus subtilis PY79 (sigF::kan). Samples were analyzed at 8 hours after exposure to the different bacteria. These studies identified C. elegans genes induced by pathogen infection. Brain-heart infusion agar plates (10 ug/ml kanamycin) were used.
