Project description:Cellular RdRPs play a critical role in the development of many organisms. Using high-throughput small RNA and messenger RNA sequencing we found that the Caenorhabditis elegans RdRP, EGO-1, is required to produce small RNAs antisense to a number of germline-expressed genes through several developmental stages. We found that these genes fall into distinct classes including genes required for kinetochore and nuclear pore assembly, as well as the production of histone-modifying and centromeric proteins. We also found several RNAi-related genes to be targets of EGO-1. Finally, we show a strong correlation between the loss of small RNAs and the rise of mRNA levels in ego-1 mutant animals. 5'-monophosphate-independent small RNA sequencing from ego-1(om84) and control L3, L4, and adult C. elegans hermaphrodites

Project description:Recent work has shown that small non-coding RNAs, including miRNAs, serve an important role in controlling gene expression during development and disease. However, little detailed information exists concerning the relative expression patterns of small RNAs during development of C. elegans. Here we use recent advances in high-throughput sequencing technology to show that expression of non-coding small RNAs, including miRNAs, changes dynamically during development and in the different sexes of C. elegans; approximately 16% of known miRNAs changed over 10 fold in expression during C. elegans development and about 12% of miRNAs showed major changes in expression between males and hermaphrodites of C. elegans. These results should lead to a better understanding of the expression and function of small RNAs in C. elegans development.

The number of sequence reads for miRNA was assessed from the raw sequence data from Solexa sequencing using perfect sequence matching to known miRNAs (miRBase Release 11.0).

Project description:We compare whole-animal RNA-seq transcriptomes for C. elegans males and hermaphrodites from the late L3 larval stage to young adulthood. During this interval, male sexual structures develop, including extensive neurogenesis and synaptogenesis that nearly doubles the size of the nervous system. Previous genome-wide expression studies in C. elegans have usually focused on only one sex â the hermaphrodite, and there are a relatively large number of predicted genes that still remain without meaningful annotation. In the present study, differential expression analysis of the RNA-seq data revealed 1,751 genes expressed at a higher level in the male. By differential expression analysis, unbiased gene correlation analysis, and a guilt-by-association approach, we identified new transcription factors required for differentiation of male genital structures, semen proteins, and candidates for previously-unknown components for synapse function. The results validate the dataset as a rich resource for future gene discovery in C. elegans. To analyze gene expression during sexual maturation in C. elegans, we performed RNA-seq for five samples for each sex ranging at 6 hr intervals from late L3 to young adult stages
