Project description:Dosage Compensation is required to correct for uneven gene dose between the sexes. We utilized global run-on sequencing (GRO-seq) to examine how Caenorhabditis elegans dosage compensation reduces transcription of X-linked genes. To facilitate these experiments, we required accurate 5’-ends of genes that have been missing due to a co-transcriptional trans-splicing event common in nematodes. We developed a modified GRO-seq protocol to identify TSSs that are supported by transcription, and determined that TSSs lie more than 1 kb upstream of the previously annotated TSS for nearly one-quarter of all genes. We then investigated the changes that occur in transcriptionally engaged RNA Polymerase when dosage compensation is disrupted, and find that dosage compensation controls recruitment of RNA Polymerase to X-linked genes.

We then investigated the changes that occur in transcriptionally engaged RNA Polymerase when dosage compensation is disrupted, and find that dosage compensation controls recruitment of RNA Polymerase to X-linked genes. GRO-seq experiments (two biological replicates) were performed in nuclei from many wild-type states and a dosage compensation mutant

GRO-cap reactions were performed with TAP, and without TAP as a control.

Project description:The nematode Caenorhabditis elegans has evolutionarily conserved EV signaling pathways. In this study, we apply a recently published method for high specificity purification of EVs from C. elegans to carry out target-independent proteomic and RNA analysis of EVs from C. elegans. Our experiments uncovered diverse coding and non-coding RNA transcripts as well as protein cargo types commonly found in human EVs.

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.
