The 21-nucleotide small temporal RNA (stRNA) let-7regulates developmental timing in Caenorhabditis elegans and probably in other bilateral animals. We present in vivo and in vitro evidence that in Drosophila melanogaster a developmentally regulated precursor RNA is cleaved by an RNA interference-like mechanism to produce mature let-7 stRNA. Targeted destruction in cultured human cells of the messenger RNA encoding the enzyme Dicer, which acts in the RNA interference pathway, leads to… 

Dicer functions in RNA interference and in synthesis of small RNA involved in developmental timing in C. elegans.

A combination of phenotypic abnormalities and RNA analysis suggests a role for dcr-1 in a regulatory pathway comprised of small temporal RNA (let-7) and its target (e.g., lin-41).

A Role for the RNase III Enzyme DCR-1 in RNA Interference and Germ Line Development in Caenorhabditis elegans

A null mutation indicer-1 (dcr-1), a gene proposed to encode the enzyme that generates short RNAs, is described and it is found that Mutant animals have defects in RNAi under some, but not all, conditions.

Kinetic Analysis of Small Silencing RNA Production by Human and Drosophila Dicer Enzymes In Vitro.

Methods for in vitro small RNA production assay using recombinant human and Drosophila Dicer proteins are described.

A microRNA in a Multiple-Turnover RNAi Enzyme Complex

It is shown that, in human cell extracts, the miRNA let-7 naturally enters the RNAi pathway, which suggests that only the degree of complementarity between a miRNA and its RNA target determines its function.

Role of Dicer in posttranscriptional RNA silencing.

Different functions of Dicer in posttranscriptional regulation are described and information about Dicer-associated proteins and their role in the biogenesis of small RNAs and assembly of RISC is discussed.

Structural features of small RNA precursors determine Argonaute loading in Caenorhabditis elegans

In C. elegans, DCR-1 is required for the maturation of both short interfering RNAs and microRNAs, which are subsequently loaded into different Argonaute proteins to mediate silencing via distinct mechanisms, and structural features that direct the small RNAs into the RNA interference (RNAi) pathway or the miRNA-processing pathway are shown.


Evidence suggests that these modular 200 kD enzymes function in the cytoplasm in conjunction with Dicer-binding proteins to generate and load small RNAs onto ribonucleoprotein complexes that effect post-transcriptional gene-silencing.

RNA Interference and Development

The involvement of the components of RNA interference is considered in spermatogenesis of Drosophila melanogaster and regulation of the expression of genes in Caenorhabditis elegans responsible for temporal patterns of development.

Roles of Cellular RNA-Dependent RNA Polymerases in Endogenous Small RNA Pathways in Caenorhabditis elegans: A Dissertation

This thesis describes genetic, deep sequencing, and molecular studies, which identify 22G-RNAs as the most abundant class of endogenous small RNA in C. elegans and shows that 22G -RNAs are dependent on and interact with members of an expanded family of worm-specific Argonaute proteins that interact with RdRPdependent small RNAs.



RNA interference is mediated by 21- and 22-nucleotide RNAs.

It is demonstrated that 21- and 22-nt RNA fragments are the sequence-specific mediators of RNAi, and evidence that the direction of dsRNA processing determines whether sense or antisense target RNA can be cleaved by the siRNA-protein complex is provided.

The lin-4 regulatory RNA controls developmental timing in Caenorhabditis elegans by blocking LIN-14 protein synthesis after the initiation of translation.

The results indicate that association of lin-4 RNA with the 3' UTR of Lin-14 mRNA permits normal biogenesis of lin -14 mRNA, and normal translational initiation, but inhibits step(s) thereafter, such as translational elongation and/or the release of stable LIN-14 protein.

A species of small antisense RNA in posttranscriptional gene silencing in plants.

The 25-nucleotide antisense RNA detected in transgene-induced PTGS is likely synthesized from an RNA template and may represent the specificity determinant of PTGS.

Function, mechanism and regulation of bacterial ribonucleases.

RNase III provides an important model with which to understand mechanisms of RNA maturation, RNA decay, and gene regulation, and is regulated by phosphorylation in the T7 phage- infected cell.

Non-coding RNAs: Lightning strikes twice

Incorporation of terminal phosphorothioates into oligonucleotides.

3'- and 5'-terminal phosphorothioates are introduced into heptameric oligonucleotides and their post-synthetic modification with several reporter groups and their reactivity for conjugation with cholesterol, bimane and for sulphydryl exchange are described.
