Project description:From a forward genetic screen for C. elegans genes required for RNAi, we identified rde-10 and through proteomic analysis of RDE-10-interacting proteins, we identified a protein complex containing the new RNAi factor RDE-11, the known RNAi factors RSD-2 and ERGO-1, as well as other candidate RNAi factors. The newly identified RNAi defective genes rde-10 and rde-11 encode a novel protein and a RING-type zinc finger domain protein, respectively. Mutations in rde-10 and rde-11 genes cause dosage-sensitive RNAi deficiencies: these mutants are resistant to low dosage, but sensitive to high dosage of double-stranded RNAs. We assessed the roles of rde-10, rde-11, and the dosage-sensitive RNAi defective genes rsd-2, rsd-6 and haf-6 in both exogenous and endogenous small RNA pathways using high-throughput sequencing and qRT-PCR. These genes are required for the accumulation of secondary siRNAs in both exogenous and endogenous RNAi pathways. Small RNA analysis by deep sequencing in various wild type and mutant C. elegans strains.

Project description:Dysfunction of the motor subunit of the TIM23 translocase, the PAM complex located on the matrix side of the mitochondrial inner membrane in Saccharomyces cerevisiae, was shown to cause a decrease in mitochondrial protein import and precursor accumulation in the cytosol. We used an analogous model to study the non-mitochondrial response to defective mitochondrial import machinery in Caenorhabditis elegans in which we depleted DNJ-21 as the functional homolog of yeast Pam18. To gain a broader insight in potential changes in Caenorhabditis elegans proteome upon DNJ-21 depletion we performed a quantitative, label-free proteomics analysis. We compared protein levels upon knockdown of dnj-21 (dnj-21 RNAi) with control conditions (Empty vector RNAi). Synchronized N2 wild type worms were grown on NGM plates seeded with E. coli HT115(DE3) transformed with a construct targeting dnj-21 gene or with empty vector L4440 as a control.

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.

Project description:Graphene oxide (GO) holds high promise for diagnostic and therapeutic applications in nanomedicine but reportedly displays immunotoxicity, underlining the need for developing functionalized GO with improved biocompatibility. Here, we study the adverse effects of GO and amino-functionalized GO (GONH2) during Caenorhabditis elegans development and ageing upon acute or chronic exposure. Chronic GO treatment throughout the C. elegans development causes decreased fecundity and a reduction of animal size, while acute treatment does not lead to any measurable physiological decline. However, RNA-Seq data reveal that acute GO exposure induces innate immune gene expression. The p38 MAP kinase, PMK-1, which is a well-established master regulator of innate immunity, protects C. elegans from chronic GO toxicity, as pmk-1 mutants show reduced tissue-functionality and facultative vivipary. In a direct comparison, GONH2 exposure does not cause detrimental effects in the wild type or in pmk-1 mutants, and the innate immune response is considerably less pronounced. Our work establishes the enhanced biocompatibility of amino-functionalized GO in a whole-organism, emphasizing its potential as biomedical nanomaterial.
