Project description:Thousands of transcripts accumulate in an oscillatory manner during C. elegans larval development. Here, we confirmed these oscillations to result from rhythmic RNA polymerase II (RNAPII) binding to these oscillating genes by performing RNAPII ChIP-seq and total RNA-seq on the same samples (see related submission)

Project description:The nematode Caenorhabditis elegans (C. elegans) is often used as a model organism to study cell and developmental biology. Quantitative mass spectrometry has only recently been performed in C. elegans and, so far, most studies have been done on adult worm samples. Here we use quantitative mass spectrometry to characterise protein level changes across the four larval developmental stages (L1-L4) of C. elegans, in biological triplicate. In total, we identify 4,130 proteins and quantify 1,541 proteins that were identified across all four stages in all three biological repeats with at least 2 unique peptides per protein. Using hierarchical clustering and functional ontological analyses, we identify 21 protein groups containing proteins with similar protein profiles across the four stages, and highlight the most overrepresented biological functions in each of these protein clusters. In addition, we use the dataset to identify putative larval stage specific proteins in each individual developmental stage, as well as in the early and late developmental stages. In summary, this dataset provides a system-wide analysis of protein level changes across the four C. elegans larval developmental stages, which serves as a useful resource for the worm development research community.

Project description:Thousands of transcripts accumulate in an oscillatory manner during C. elegans larval development. Here, we performed total RNA sequencing to confirm and quantify transcript levels oscillations on samples that we used in parallel to probe rhythmic RNA polymerase II recruitment to these genes as a mechanism to generate RNA level oscillations (see parallel submission of ChIP-seq data)

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.
