Project description:We performed RNA-seq to quantify gene expression changes in adult worms upon knockdown of transcription factor unc-62/Homothorax. unc-62 is a developmental regulator that binds proximal to age-regulated transcripts and modulates lifespan. In the intestine (in which tissue-specific unc-62 knockdown increases lifespan), we identify multiple effects of unc-62 knockdown linked to extension of longevity. First, unc-62 RNAi decreases the expression of yolk proteins (vitellogenins) that aggregate in the body cavity and become toxic in old age. Second, unc-62 RNAi results in a broad increase in expression of intestinal genes that typically decrease expression with age, suggesting that unc-62 activity balances intestinal resource allocation between yolk protein expression and fertility on the one hand and somatic functions on the other.

Project description:Homozygous mutant dcr-1 animals were analyzed by Affymetrix microarray analysis using whole worm adult animals. The worms was genetically marked with a recessive allele of unc-32 that exhibits a coiler phenotype in unc-32 homozygous null animals. The "wildtype" comparison worm used in this study were coiling unc-32 animals and the dcr-1 deficient animal contained both the dcr-1 and the unc-32 mutations. Worms were picked and pooled for analysis. <br>Wormbase concise description of dcr-1 (DiCer Related): The dcr-1 gene encodes a bidentate ribonuclease that is homologous to E. coli RNAse III; dcr-1 is required both for RNA interference and for synthesis of small developmental RNAs; DCR-1 interacts in vivo with RDE-4, a double-stranded RNA (dsRNA) binding protein required for RNAi that interacts with trigger dsRNAs and may function to deliver dsRNAs to DCR-1 for endonucleolytic processing.

Project description:Argonaute proteins (AGOs) are key nuclease effectors of RNA interference (RNAi) [1]. Although purified AGOs can mediate a single round of target-RNA cleavage in vitro, accessory factors are required for siRNA loading and to achieve multiple-target turnover [2, 3]. To identify AGO co-factors we immunoprecipitated the C. elegans AGO WAGO-1, which engages amplified small RNAs during RNAi [4]. These studies identified a robust association between WAGO-1 and a conserved Vasa ATPase-related protein RDE-12. rde-12 mutants are deficient in RNAi including viral suppression, and fail to produce amplified secondary siRNAs and certain endogenous siRNAs (endo-siRNAs). RDE-12 co-localizes with WAGO-1 in germline P-granules and to peri-nuclear cytoplasmic foci in somatic cells. These findings and our genetic studies suggest that (i) RDE-12 is first recruited to target mRNAs by upstream AGOs (RDE-1 and ERGO-1) where it promotes small-RNA amplification and/or WAGO-1 loading, and that (ii) downstream of these events, RDE-12 forms an RNase-resistant (target mRNA-independent) complex with WAGO-1 that may scan for additional target mRNAs. Examine small RNA population changes in rde-12 mutants

Project description:In this study we show that global levels of mature miRNAs are unaffected in C. elegans after knockdown of either subunit of CK2 (encoded by kin-3 and kin-10) by RNAi. Small RNAs were quantified from wild-type animals at L4 stage fed either vector (L4440), kin-3, kin-10, or alg-1 RNAi. Mature miRNA counts were quantified by summing the total number of reads mapping to each miRNA and normalized to the total number of mapped reads per sequencing library.
