Development of a model system to study the role of chromatin factors during transgenerational epigenetic inheritance (TEI) in C. elegans

Ziel

Non DNA-sequence based inheritance has been observed in many organisms from microbes to man and likely impacts public health. The mechanisms of non DNA-sequence based inheritance remain largely unknown. However, some examples of non DNA-sequence based inheritance in mammals, plants and invertebrates are linked to the control of selfish, transposable elements in the genome. Here we propose to discover the mechanistic basis of multi-generational non DNA-sequence based inheritance, also referred to as transgenerational epigenetic inheritance (TEI), using the laboratory animal model Caenorhabditis elegans. Specifically, our goal is to identify chromatin and non-coding RNA “epigenetic” marks that transfer information from generation to generation in C. elegans. C. elegans is a great model for this work as it has a generation time of only three days, has a powerful genetics toolkit and its chromatin and RNA pathways are largely conserved in humans. Towards this goal we have established a novel assay we named piRNA-related insertional chromatin immunoprecipitation (piChIP). Using this piChIP system, our specific aims are:
Aim-1: Identification of novel non-coding RNAs in the germline nuclear RNAi pathway
- Method: RNA-seq
Aim-2: Identification of novel proteins and histone PTMs in the germline nuclear RNAi pathway
- Method: SILAC proteomics and Mass Spectrometry
