Project description:We report the identification of small RNAs in undifferentiated (d0) and differentiating (d4) mouse embryonic stem (ES) cells using high-throughput sequencing. The goal of this study was to identify small RNAs involved in X-chromosome inactivation (XCI). We have identified a subset of small RNAs that are generated from transposon sequences and map to the X-chromosome, suggesting their involvement in transposon control on the inactivating X-chromosome.
Project description:Small RNAs are emerging as important molecules for cross-species communication. Thanks to available and affordable sequencing technologies it is now possible to sequence small RNAs (sRNA-Seq) present in samples of interacting organisms. A first step when analyzing sRNA-Seq of two interacting species is to determine which sequences are being produced by which organism. Due to their small size (18-30), small RNAs could easily map to both host and parasite genomes. Here we produced data for Mus musculus intestinal epithelial cells treated with Extracellular Vesicles (EV) produced by the parasitic nematode Heligmosomoides bakeri.
