Project description:Piwi-related Argonaute proteins play important roles in maintaining germline integrity and fertility and have been linked to a class of germline-enriched small RNAs termed piRNAs. Caenorhabditis elegans encodes two Piwi family proteins called PRG-1 and PRG-2, and PRG-1 interacts with the C. elegans piRNAs (21U-RNAs). Previous studies found that the prg-1 mutation causes a marked reduction in the expression of 21U-RNAs, temperature-sensitive defects in fertility and other phenotypic defects.To systematically demonstrate the function of PRG-1 on regulating small RNAs and their targets. We use recent advances in high-throughput sequencing technology to show that expression of non-coding small RNAs in six stages(embryo,L1,L2,L3,L4,young audlt) and mRNAs in four stages (L1,L2,L3,L4) after prg-1 mutation. prg-1 mutation can not only lead to a decrease in the expression of 21U-RNAs, but also cause 35~40% of miRNAs to be significantly down-regulated; approximately 3% (6.00% in L4) of protein-coding genes are differentially expressed after mutating prg-1, and 60~70% of these substantially changed protein-coding genes are up-regulated.

Project description:These datasets examine the association of small RNAs with 3p hydroxyls (including endo-siRNAs, miRNAs, and 21U-RNAs) with the PRG-1 protein through co-immunoprecipitation. Two datasets are provided; one sequences small RNAs that co-IP with PRG-1; the other sequences small RNAs from the IP input sample. These RNA samples were prepared using an approach that captures small RNAs independent of the covalent status of their 5p termini, as described in Ambros et al. (2003) Curr Biol 13:807-18. These datasets were prepared in the Craig C. Mello laboratory. Keywords: identification of PRG-1-associated small RNAs
