Project description:Investigation of whole genome gene expression level changes in early generation Caenorhabditis elegans Bristol N2 prg-1 and Bristol N2 prg-1; daf-2 double mutant, compared to late-generation strains. A seven chip study using total RNA recovered from three separate alleles of Caenorhabditis elegans Bristol N2 prg-1 and four separate allelic combinations of a double mutant strain, Bristol N2 prg-1; daf-2 , in which prg-1 (pk2298) and prg-1 (tm872) are combined with one of three daf-2 alleles (e1368, 1370, m41).
Project description:Investigation of whole genome gene expression level changes in early generation Caenorhabditis elegans Bristol N2 rsd-2 and Bristol N2 rsd-6 single mutants, compared to late-generation strains at 25°C and 20°C
Project description:Transcriptome profiling of three models with impaired insulin/IGF1 signaling. 1. Deep sequencing of endogenous mRNA from Caenorhabditis elegans N2 var. Bristol (wildtype) and daf-2(e1370) mutant; 2. Deep sequencing of endogenous mRNA from murine embryonic fibroblasts (MEF) wildtype and irs1-/- knockout; 3. Deep sequencing of endogenous mRNA from murine embryoinic fibroblast (MEF) insr+/- -lox and insr+/- knockout 14 samples examined: C. elegans N2 var. Bristol (wildtype) vs. daf-2(e1370) mutant; MEF wildtype vs. irs1-/- knockout; MEF insr+/- -lox vs. insr +/- knockout
Project description:To exmine the role of nonsense-mediated mRNA decay process in the longevity regulation of daf-2 mutants, we sequenced transcriptomes from day 1 adult Caenorhabditis elegans: Bristol N2 (wild-type), and smg-2(qd101), daf-2(e1370) and smg-2(qd101); daf-2(e1370) mutants.
Project description:Investigation of whole genome gene expression level changes in early generation Caenorhabditis elegans Bristol N2 rsd-2 and Bristol N2 rsd-6 single mutants, compared to late-generation strains at 25°C and 20°C A six chip study using total RNA recovered from two separate alleles of Caenorhabditis elegans Bristol N2 rsd-2 and one allele Bristol N2 rsd-6 , in which the effects of transgeneration aging are studied in early generation animals and late generation animals at the restrictive temperature of 25°C and the permissive temperature, 20°C.
Project description:Natural genetic variation is the raw material of evolution and influences disease development and progression. To analyze the effect of the genetic background on protein expression in the nematode C. elegans (Caenorhabditis elegans), the two genetically highly divergent wild-type strains N2 (Bristol) and CB4856 (Hawaii) were compared quantitatively. In total, we quantified 3,238 unique proteins in three independent SILAC (stable isotope labeling by amino acids in cell culture) experiments. The differentially expressed proteins were enriched for genes that function in insulin-signaling and stress response pathways.
