Adult aging in C. elegans

ABSTRACT: We wished to study normal adult aging in C. elegans. We competitively hybridized a series of experimental samples (experimental variable: adult age) against a common reference sample. We use the CF512 fer-15(b26) II; fem-1 (hc17) IV mutant strain, which has defective spermatids which fail to activate into spermatozoa at 25C. Culturing this strain at 25C prevented self-fertilization and therefore eliminated contributions from embryonic transcripts. CF512 animals develop an otherwise-normal germ line; their lifespan and aging are similar to wild-type animals. We axenized eggs and then synchronized animals via L1 arrest. Populations were very tightly synchronized. Animals were cultured at 25C. Samples were extracted and hybridized as described in protocols at http://microarrays.org.

RNAi knock down of daf-2, daf-3, daf-16 in C. elegans over 0-48 hours

Project description:Comparison of sterile worms grown on Control Vector, daf-2 RNAi, and daf-2 + daf-16 RNAi. Synchronized fer-15(b26); fem-1(hc17) animals were grown on RNAi bacteria at 25ºC, induced with IPTG on Day 1 of adulthood, and collected from 0-48 hours (10 time points) and 0-196 hours (10 time points); RNAi bacteria was supplemented as necessary for later time points. Worms were floated off lawns with M9 buffer, centrifuged, and washed again in M9. The pelleted worms were dissolved in Trizol (Gibco) and frozen in liquid nitrogen.Time courses were compared with mixed references (collected from 1/2 of each of the time course samples)

Response of C. elegans immune pathway mutants to P. aeruginosa infection

Project description:Synchronized C. elegans cultures of three geontypes -- wildype N2, daf-2(e1370) and sma-6(wk7) -- were prepared using standard techniques (http://cmgm.stanford.edu/~kimlab/index_methods.html). Live young adult worms were split between NG plates pre-seeded with the non-pathogenic E. coli strain OP50 or the Pseudomonas aeruginosa clinical isolate PA14 and incubated at 25C for 4 or 24 hours before harvesting. This experiment was repeated at least three times on independent occasions. cDNA probes were prepared from experimental samples and from reference mRNA extracted from mixed stage wild type worms grown at 25C, and were labeled with Cy3 or Cy5, as indicated. A reference experiement design type is where all samples are compared to a common reference. Elapsed Time: Time Infection: Exposure to the non-pathogenic E. coli strain OP50 or to the pathogenic Pseudomonas aeruginosa strain PA14 Strain Name: C. elegans wildtype strain N2 or the immune pathway mutants daf-2(e1370) or sma-6(wk7) Keywords: reference_design

Responses to P. aeruginosa infection - Shapira

Project description:Synchronized C. elegans cultures were prepared using standard techniques (http://cmgm.stanford.edu/~kimlab/index_methods.html). Live young adult worms were split between NG plates pre-seeded with the non-pathogenic E. coli strain OP50 or the Pseudomonas aeruginosa clinical isolate PA14 and incubated at 25C for 4, 12 or 24 hours before harvesting. This experiment was repeated three times on independent occasions. cDNA probes were prepared from experimental samples and from reference mRNA extracted from mixed stage wild type worms grown at 25C, and were labeled with Cy3 or Cy5, respectively. In the paper corresponding to this experiment set colors were flipped for easier visualization (probes from experimental samples are represented with red, probes from reference RNA are represented with green). Groups of assays that are related as part of a time series.

Caenorhabditis elegans infected with Staphylococcus aureus

Project description:Young adult fer-15;fem-1 Caenorhabditis elegans were infected with Staphylococcus aureus for 8 h to determine the transcriptional host response to Staphylococcus aureus. Analysis of differential gene expression in C. elegans young adults exposed to two different bacteria: E. coli strain OP50 (control), wild-type Staphylococcus aureus RN6390. Samples were analyzed at 8 hours after exposure to the different bacteria. These studies identified C. elegans genes induced by pathogen infection.

Transcription profiling of muscle from wild type and fer-1 mutant C. elegans

Project description:In vertebrate muscle, loss of Dysferlin results in the activation of compensatory muscle gene expression, even at pre-pathological stages. We hypothesized that if C. elegans fer-1 is also expressed in muscle, then fer-1 mutant worms might also exhibit compensatory muscle gene expression. To test this hypothesis, we used Affymetrix microarrays to profile gene expression from synchronized wild type and fer-1 mutant adults. To improve the specificity of this approach, we profiled two well characterized loss-of-function fer-1 mutants (hc1ts and hc24ts) and considered genes that changed similarly in both mutants as fer-1-regulated transcripts. Experiment Overall Design: For each genotype, six individual replicates were performed and were hybridized to Affymetrix C. elegans Genechips using the manufacturerâs recommended protocols. The best four preparations (as determined by the overall Pearson Correlation within a genotype) were used for RNA labeling and hybridization.
