Project description:To identify changes in gene expression in age-1 mutants, we compared expression in fer-15(b26) animals to expression in fer-15(b26); age-1(hx542) mutants. We prepared RNA from young adult fer-15(b26) mutants grown at 25?C (five samples prepared at Stanford University and six samples prepared at the University of Colorado) and young adult fer-15(b26); age-1(hx542) mutants (four samples at Stanford University and six samples at the University of Colorado). Set of arrays that are part of repeated experiments Place of growth: Stanford vs Colorado Genotype: mutant strains vs wt (N2) mixed stage; some expts are reverse dye

Project description:To identify changes in gene expression in daf-16 mutants, we compared expression in fer-15 young adults to expression in fer-15(b26); daf-16(m26) young adults grown at 25?C. At Stanford University, four samples of fer-15 and five samples of fer-15; daf-16 animals were prepared. At the University of Colorado, seven samples of fer-15 and six samples of fer-15; daf-16 was prepared. Set of arrays that are part of repeated experiments Place of growth: At Stanford vs Colorado Genotype: mutant strains vs wt (N2) mixed stage; some expts are reverse dye (wt in channel 2)

Project description: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. Keywords = aging Keywords: time-course
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. Keywords: response to pathogen infection, innate immunity, host-pathogen interactions
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)
