Molecular Strategies of the Caenorhabditis elegans Dauer Larva to Survive Extreme Desiccation

ABSTRACT: Many organisms in the nature can drive themselves into an ametabolic state known as anhydrobiosis upon extreme desiccation. The nematode C. elegans is one of them. However, the anhydrobiotic ability of the worm is limited to a special developmental stage known as the dauer. Besides, the dauer larvae must be first treated by a mild desiccation stress (preconditioning) so that they gain desiccation tolerance. In this study, we investigated the differential gene expression during preconditioning in the C. elegans dauer.

Massive water loss is a serious challenge for terrestrial animals, which usually has fatal consequences. However, some organisms have developed means to survive this stress by entering an ametabolic state called anhydrobiosis. The molecular and cellular mechanisms underlying this phenomenon are poorly understood. We recently showed that Caenorhabditis elegans dauer larva, an arrested stage specialized for survival in adverse conditions, is resistant to severe desiccation. However, this requires ...[more]

P. pacificus : Dauers and Dauer-Exit at 12 hour time-point vs. Mix-stage worms

Project description:Transcriptional profiling of P. pacificus worms from (1) dauer stage, or (2) dauer-exit at 12 hours stage, compared to mix-stage worms as a common reference. The goal was to determine genes regulated during dauer development and recovery or exit from dauer stage. This data was then compared to data generated for corresponding developmental stages in the C. elegans (see NCBI GEO series GSE30977) , to study evolution of developmental pathways regulating dauer development. Two-condition experiments. Experiment 1 = Dauers vs. Mix-stage worms. 4 biological replicates for each condition, including 2 dye-swaps. Experiment 2 = Dauer-Exit at 12 hour time-point s vs. Mix-stage worms. 3 biological replicates for each condition, including 1 dye-swaps. Total samples from both experiments 1 and 2 = 7.

RNA-seq of whole animal tissue and AWA olfactory neurons isolated by FACS from control and post-dauer L4 larval stage C. elegans

Project description:Developmental experiences play critical roles in shaping adult physiology and behavior. We and others previously showed that adult C. elegans which transiently experienced dauer arrest during development (PD: post-dauer) exhibit distinct gene expression profiles as compared to control adults which bypassed the dauer stage. In particular, the expression patterns of subsets of chemoreceptor genes are markedly altered in PD adults. Whether altered chemoreceptor levels drive plasticity in chemosensory behaviors in PD adults is unknown. Via transcriptional profiling of sorted populations of AWA neurons from control and PD adults, we further show that the expression of a subset of chemoreceptor genes in AWA are differentially regulated in PD animals. Our results suggest that developmental experiences may be encoded at the level of olfactory receptor regulation, and provide an elegant mechanism by which C. elegans is able to precisely modulate its behavioral preferences as a function of its current and past experiences.

Dynamic changes of histone H3 marks during Caenorhabditis elegans lifecycle revealed by middle-down proteomics

Project description:We applied a middle-down proteomics strategy for large scale protein analysis during in vivo development of Caenorhabditis elegans. We characterized post-translational modifications (PTMs) on histone H3 N-terminal tails at eight time points during the C. elegans lifecycle, including embryo, larval stages (L1 to L4), dauer and L1/L4 post dauer. Histones were analyzed by our optimized middle-down protein sequencing platform using high mass accuracy tandem mass spectrometry. This allows quantification of intact histone tails and detailed characterization of distinct histone tails carrying co-occurring PTMs. We measured temporally distinct combinatorial PTM profiles during C. elegans development. We show that the doubly modified form H3K23me3K27me3, which is rare or non-existent in mammals, is the most abundant PTM in all stages of C. elegans lifecycle. The abundance of H3K23me3 increased during development and it was mutually exclusive of the active marks H3K18ac, R26me1 and R40me1, suggesting a role for H3K23me3 in to silent chromatin. We observed distinct PTM profiles for normal L1 larvae and for L1-post dauer larvae, or L4 and L4 post-dauer, suggesting that histone PTMs mediate an epigenetic memory that is transmitted during dauer formation. Collectively, our data describe the dynamics of histone H3 combinatorial code during C. elegans lifecycle and demonstrate the feasibility of using middle-down proteomics to study in vivo development of multicellular organisms.
