Project description:This experiment investigates changes in gene expression upon Orsay virus infection and between males and hermaphrodites in the nematode Ceanorhabditis elegans. The laboratory reference strain N2 was used. For this strain, males are less susceptible to Orsay virus infection than hermaphrodites. The goal of the experiment was to identify genes that show different expression patterns for both sexes upon Orsay virus infection. We mock-treated or infected 48h-old C. elegans populations with Orsay virus and took samples 30-hours after infection. For each treatment-sex combination 8 samples were collected. Thereafter RNA was isolated, labelled, and hybridized on microarray. The gene-expression dynamics of previously identified genes (e.g. from literature and from a highly replicated N2 versus CB4856 experiment) were analyzed.

Project description:We compare whole-animal RNA-seq transcriptomes for C. elegans males and hermaphrodites from the late L3 larval stage to young adulthood. During this interval, male sexual structures develop, including extensive neurogenesis and synaptogenesis that nearly doubles the size of the nervous system. Previous genome-wide expression studies in C. elegans have usually focused on only one sex – the hermaphrodite, and there are a relatively large number of predicted genes that still remain without meaningful annotation. In the present study, differential expression analysis of the RNA-seq data revealed 1,751 genes expressed at a higher level in the male. By differential expression analysis, unbiased gene correlation analysis, and a guilt-by-association approach, we identified new transcription factors required for differentiation of male genital structures, semen proteins, and candidates for previously-unknown components for synapse function. The results validate the dataset as a rich resource for future gene discovery in C. elegans.

Project description:Gene expression in plep-1 mutant young adult hermaphrodites
| PRJNA282495 | ENA
Project description:In this experiment, steady-state mRNA levels were determined for replicated samples of N2 (wild-type reference) and fog-2(q71) homozygous mutant C. elegans. All samples were adult XX animals, which for N2 are self-fertile hermaphrodites and for fog-2(q71) spermless hermaphrodites, i.e. true females. For the fog-2 mutant animals, only those that had mated with males, and were thus gravid, were picked for RNA isolation. This ensures that all comparisons are between similar, embryo-containing animals. The experiment was motivated by the role of FOG-2 in post-transcriptional control of gene expression in germ cells, inferred from its the germline-specific phenotype of its loss and from its physical associated with the GLD-1 RNA-binding protein. Specifically, a possible role for FOG-2 in influencing mRNA stability was addressed.

During this interval, male sexual structures develop, including extensive neurogenesis and synaptogenesis that nearly doubles the size of the nervous system. Previous genome-wide expression studies in C. elegans have usually focused on only one sex â the hermaphrodite, and there are a relatively large number of predicted genes that still remain without meaningful annotation. In the present study, differential expression analysis of the RNA-seq data revealed 1,751 genes expressed at a higher level in the male. By differential expression analysis, unbiased gene correlation analysis, and a guilt-by-association approach, we identified new transcription factors required for differentiation of male genital structures, semen proteins, and candidates for previously-unknown components for synapse function. The results validate the dataset as a rich resource for future gene discovery in C. elegans. To analyze gene expression during sexual maturation in C. elegans, we performed RNA-seq for five samples for each sex ranging at 6 hr intervals from late L3 to young adult stages
