Argonaute Proteins
A family of RNA-binding proteins that has specificity for MICRORNAS and SMALL INTERFERING RNA molecules. The proteins take part in RNA processing events as core components of RNA-induced silencing complex.
Eukaryotic Initiation Factors
Peptide initiation factors from eukaryotic organisms. Over twelve factors are involved in PEPTIDE CHAIN INITIATION, TRANSLATIONAL in eukaryotic cells. Many of these factors play a role in controlling the rate of MRNA TRANSLATION.
RNA-Induced Silencing Complex
A multicomponent, ribonucleoprotein complex comprised of one of the family of ARGONAUTE PROTEINS and the "guide strand" of the one of the 20- to 30-nucleotide small RNAs. RISC cleaves specific RNAs, which are targeted for degradation by homology to these small RNAs. Functions in regulating gene expression are determined by the specific argonaute protein and small RNA including siRNA (RNA, SMALL INTERFERING), miRNA (MICRORNA), or piRNA (PIWI-INTERACTING RNA).
RNA Interference
A gene silencing phenomenon whereby specific dsRNAs (RNA, DOUBLE-STRANDED) trigger the degradation of homologous mRNA (RNA, MESSENGER). The specific dsRNAs are processed into SMALL INTERFERING RNA (siRNA) which serves as a guide for cleavage of the homologous mRNA in the RNA-INDUCED SILENCING COMPLEX. DNA METHYLATION may also be triggered during this process.
Ribonuclease III
An endoribonuclease that is specific for double-stranded RNA. It plays a role in POST-TRANSCRIPTIONAL RNA PROCESSING of pre-RIBOSOMAL RNA and a variety of other RNA structures that contain double-stranded regions.
MicroRNAs
Small double-stranded, non-protein coding RNAs, 21-25 nucleotides in length generated from single-stranded microRNA gene transcripts by the same RIBONUCLEASE III, Dicer, that produces small interfering RNAs (RNA, SMALL INTERFERING). They become part of the RNA-INDUCED SILENCING COMPLEX and repress the translation (TRANSLATION, GENETIC) of target RNA by binding to homologous 3'UTR region as an imperfect match. The small temporal RNAs (stRNAs), let-7 and lin-4, from C. elegans, are the first 2 miRNAs discovered, and are from a class of miRNAs involved in developmental timing.
RNA, Small Interfering
Small double-stranded, non-protein coding RNAs (21-31 nucleotides) involved in GENE SILENCING functions, especially RNA INTERFERENCE (RNAi). Endogenously, siRNAs are generated from dsRNAs (RNA, DOUBLE-STRANDED) by the same ribonuclease, Dicer, that generates miRNAs (MICRORNAS). The perfect match of the siRNAs' antisense strand to their target RNAs mediates RNAi by siRNA-guided RNA cleavage. siRNAs fall into different classes including trans-acting siRNA (tasiRNA), repeat-associated RNA (rasiRNA), small-scan RNA (scnRNA), and Piwi protein-interacting RNA (piRNA) and have different specific gene silencing functions.
Alpha-Amanitin
A cyclic octapeptide with a thioether bridge between the cystine and tryptophan. It inhibits RNA POLYMERASE II. Poisoning may require LIVER TRANSPLANTATION.
Eukaryotic Initiation Factor-2
Eukaryotic initiation factor of protein synthesis. In higher eukaryotes the factor consists of three subunits: alpha, beta, and gamma. As initiation proceeds, eIF-2 forms a ternary complex with Met-tRNAi and GTP.
Cytoplasmic Structures
Components of the cytoplasm excluding the CYTOSOL.
Gene Silencing
Interruption or suppression of the expression of a gene at transcriptional or translational levels.
RNA-Binding Proteins
Proteins that bind to RNA molecules. Included here are RIBONUCLEOPROTEINS and other proteins whose function is to bind specifically to RNA.
RNA, Guide
Small kinetoplastid mitochondrial RNA that plays a major role in RNA EDITING. These molecules form perfect hybrids with edited mRNA sequences and possess nucleotide sequences at their 5'-ends that are complementary to the sequences of the mRNA's immediately downstream of the pre-edited regions.
Drosophila Proteins
Proteins that originate from insect species belonging to the genus DROSOPHILA. The proteins from the most intensely studied species of Drosophila, DROSOPHILA MELANOGASTER, are the subject of much interest in the area of MORPHOGENESIS and development.
RNA Stability
The extent to which an RNA molecule retains its structural integrity and resists degradation by RNASE, and base-catalyzed HYDROLYSIS, under changing in vivo or in vitro conditions.
Caenorhabditis elegans Proteins
Proteins from the nematode species CAENORHABDITIS ELEGANS. The proteins from this species are the subject of scientific interest in the area of multicellular organism MORPHOGENESIS.
Peptide Initiation Factors
Protein factors uniquely required during the initiation phase of protein synthesis in GENETIC TRANSLATION.
RNA, Double-Stranded
RNA consisting of two strands as opposed to the more prevalent single-stranded RNA. Most of the double-stranded segments are formed from transcription of DNA by intramolecular base-pairing of inverted complementary sequences separated by a single-stranded loop. Some double-stranded segments of RNA are normal in all organisms.
Protein Structure, Tertiary
The level of protein structure in which combinations of secondary protein structures (alpha helices, beta sheets, loop regions, and motifs) pack together to form folded shapes called domains. Disulfide bridges between cysteines in two different parts of the polypeptide chain along with other interactions between the chains play a role in the formation and stabilization of tertiary structure. Small proteins usually consist of only one domain but larger proteins may contain a number of domains connected by segments of polypeptide chain which lack regular secondary structure.
Caenorhabditis elegans
A species of nematode that is widely used in biological, biochemical, and genetic studies.
Drosophila melanogaster
A species of fruit fly much used in genetics because of the large size of its chromosomes.
RNA Processing, Post-Transcriptional
Post-transcriptional biological modification of messenger, transfer, or ribosomal RNAs or their precursors. It includes cleavage, methylation, thiolation, isopentenylation, pseudouridine formation, conformational changes, and association with ribosomal protein.
RNA, Messenger
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
Germ Cells
The reproductive cells in multicellular organisms at various stages during GAMETOGENESIS.
Immunoprecipitation
The aggregation of soluble ANTIGENS with ANTIBODIES, alone or with antibody binding factors such as ANTI-ANTIBODIES or STAPHYLOCOCCAL PROTEIN A, into complexes large enough to fall out of solution.
Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.

Mutation
Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.
Base Sequence
The sequence of PURINES and PYRIMIDINES in nucleic acids and polynucleotides. It is also called nucleotide sequence.
RNA
A polynucleotide consisting essentially of chains with a repeating backbone of phosphate and ribose units to which nitrogenous bases are attached. RNA is unique among biological macromolecules in that it can encode genetic information, serve as an abundant structural component of cells, and also possesses catalytic activity. (Rieger et al., Glossary of Genetics: Classical and Molecular, 5th ed)
Cell Line
Established cell cultures that have the potential to propagate indefinitely.
Gene Expression Regulation
Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control (induction or repression) of gene action at the level of transcription or translation.
Amino Acid Sequence
The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining PROTEIN CONFORMATION.
RNA, Plant
Ribonucleic acid in plants having regulatory and catalytic roles as well as involvement in protein synthesis.
RNA Cleavage
A reaction that severs one of the sugar-phosphate linkages of the phosphodiester backbone of RNA. It is catalyzed enzymatically, chemically, or by radiation. Cleavage may be exonucleolytic, or endonucleolytic.

Stem cells: A tale of two kingdoms. (1/823)

Homologous genes have recently been shown to regulate stem cell maintenance in animals and plants. This discovery should facilitate elucidation of the poorly understood factors that control stem cell maintenance and differentiation.  (+info)

piwi encodes a nucleoplasmic factor whose activity modulates the number and division rate of germline stem cells. (2/823)

piwi represents the first class of genes known to be required for stem cell self-renewal in diverse organisms. In the Drosophila ovary, piwi is required in somatic signaling cells to maintain germline stem cells. Here we show that piwi encodes a novel nucleoplasmic protein present in both somatic and germline cells, with the highly conserved C-terminal region essential for its function. Removing PIWI protein from single germline stem cells significantly decreases the rate of their division. This suggests that PIWI has a second role as a cell-autonomous promoter of germline stem cell division. Consistent with its dual function, over-expression of piwi in somatic cells causes an increase both in the number of germline stem cells and the rate of their division. Thus, PIWI is a key regulator of stem cell division - its somatic expression modulates the number of germline stem cells and the rate of their division, while its germline expression also contributes to promoting stem cell division in a cell-autonomous manner.  (+info)

AGO1, QDE-2, and RDE-1 are related proteins required for post-transcriptional gene silencing in plants, quelling in fungi, and RNA interference in animals. (3/823)

Introduction of transgene DNA may lead to specific degradation of RNAs that are homologous to the transgene transcribed sequence through phenomena named post-transcriptional gene silencing (PTGS) in plants, quelling in fungi, and RNA interference (RNAi) in animals. It was shown previously that PTGS, quelling, and RNAi require a set of related proteins (SGS2, QDE-1, and EGO-1, respectively). Here we report the isolation of Arabidopsis mutants impaired in PTGS which are affected at the Argonaute1 (AGO1) locus. AGO1 is similar to QDE-2 required for quelling and RDE-1 required for RNAi. Sequencing of ago1 mutants revealed one amino acid essential for PTGS that is also present in QDE-2 and RDE-1 in a highly conserved motif. Taken together, these results confirm the hypothesis that these processes derive from a common ancestral mechanism that controls expression of invading nucleic acid molecules at the post-transcriptional level. As opposed to rde-1 and qde-2 mutants, which are viable, ago1 mutants display several developmental abnormalities, including sterility. These results raise the possibility that PTGS, or at least some of its elements, could participate in the regulation of gene expression during development in plants.  (+info)

A global profile of germline gene expression in C. elegans. (4/823)

We used DNA microarrays to profile gene expression patterns in the C. elegans germline and identified 1416 germline-enriched transcripts that define three groups. The sperm-enriched group contains an unusually large number of protein kinases and phosphatases. The oocyte-enriched group includes potentially new components of embryonic signaling pathways. The germline-intrinsic group, defined as genes expressed similarly in germlines making only sperm or only oocytes, contains a family of piwi-related genes that may be important for stem cell proliferation. Finally, examination of the chromosomal location of germline transcripts revealed that sperm-enriched and germline-intrinsic genes are nearly absent from the X chromosome, but oocyte-enriched genes are not.  (+info)

Human CD34(+) stem cells express the hiwi gene, a human homologue of the Drosophila gene piwi. (5/823)

Hematopoietic stem cells (HSCs) are characterized by their dual abilities to undergo differentiation into multiple hematopoietic cell lineages or to undergo self-renewal. The molecular basis of these properties remains poorly understood. Recently the piwi gene was found in the embryonic germline stem cells (GSCs) of Drosophila melanogaster and has been shown to be important in GSC self-renewal. This study demonstrated that hiwi, a novel human homologue of piwi, is also present in human CD34(+) hematopoietic progenitor cells but not in more differentiated cell populations. Placing CD34(+) cells into culture conditions that supported differentiation and rapid exit from the stem cell compartment resulted in a loss of hiwi expression by day 5 of a 14-day culture period. Expression of the hiwi gene was detected in many developing fetal and adult tissues. By means of 5' RACE cloning methodology, a novel putative full-length hiwi complementary DNA was cloned from human CD34(+) marrow cells. At the amino acid level, the human HIWI protein was 52% homologous to the Drosophila protein. The transient expression of hiwi in the human leukemia cell line KG1 resulted in a dramatic reduction in cellular proliferation. Overexpression of hiwi led to programmed cell death of KG1 cells as demonstrated by the Annexin V assay system. These studies suggest that hiwi maybe an important negative developmental regulator, which, in part, underlies the unique biologic properties associated with hematopoietic stem and progenitor cells.  (+info)

Stem cells: so what's in a niche? (6/823)

Much effort is being invested in defining the intrinsic and extrinsic factors that control stem cell maintenance and proliferation. Recent studies have identified a signaling hierarchy involved in coordinating the proliferation of germ line and somatic stem cells in the Drosophila ovary.  (+info)

Yb modulates the divisions of both germline and somatic stem cells through piwi- and hh-mediated mechanisms in the Drosophila ovary. (7/823)

The coordinated division of distinctive types of stem cells within an organ is crucial for organogenesis and homeostasis. Here we show genetic interactions among fs(1)Yb (Yb), piwi, and hedgehog (hh) that regulate the division of both germline stem cells (GSCs) and somatic stem cells (SSCs), the two constituent stem cell populations of the Drosophila ovary. Yb is required for both GSC and SSC divisions; loss of Yb function eliminates GSCs and reduces SSC division, while Yb overexpression increases GSC number and causes SSC overproliferation. We also show that Yb acts via the piwi- and hh-mediated signaling pathways that emanate from the same signaling cells to control GSC and SSC division, respectively. hh signaling also has a minor effect in GSC division.  (+info)

Argonaute2, a link between genetic and biochemical analyses of RNAi. (8/823)

Double-stranded RNA induces potent and specific gene silencing through a process referred to as RNA interference (RNAi) or posttranscriptional gene silencing (PTGS). RNAi is mediated by RNA-induced silencing complex (RISC), a sequence-specific, multicomponent nuclease that destroys messenger RNAs homologous to the silencing trigger. RISC is known to contain short RNAs ( approximately 22 nucleotides) derived from the double-stranded RNA trigger, but the protein components of this activity are unknown. Here, we report the biochemical purification of the RNAi effector nuclease from cultured Drosophila cells. The active fraction contains a ribonucleoprotein complex of approximately 500 kilodaltons. Protein microsequencing reveals that one constituent of this complex is a member of the Argonaute family of proteins, which are essential for gene silencing in Caenorhabditis elegans, Neurospora, and Arabidopsis. This observation begins the process of forging links between genetic analysis of RNAi from diverse organisms and the biochemical model of RNAi that is emerging from Drosophila in vitro systems.  (+info)

A Tetrahymena Hsp90 co‐chaperone promotes siRNA loading by ATP‐dependent and ATP‐independent mechanisms | The EMBO JournalA Tetrahymena Hsp90 co‐chaperone promotes siRNA loading by ATP‐dependent and ATP‐independent mechanisms | The EMBO Journal
Small RNA‐mediated silencing pathways regulate a variety of cellular processes in eukaryotes (Dueck & Meister, 2014). Their effector complex, the RNA‐induced silencing complex (RISC), consists of an Argonaute protein bound by an approximately 20‐ to 30‐nt small RNA. Three major classes of Argonaute‐bound small RNAs exist. MicroRNAs (miRNAs) and small interfering RNAs (siRNAs) are processed from double‐stranded RNA precursors by the RNase III enzyme Dicer. They are loaded into the AGO subfamily of Argonaute proteins as an RNA duplex, and one of the two strands (the passenger strand) is then removed to form a mature RISC. In contrast, the third class of small RNAs, Piwi‐interacting RNAs (piRNAs), are suggested to be produced from single‐stranded precursor RNAs independently of Dicer and are loaded into the Piwi subfamily of Argonaute proteins.. In vitro RISC assembly assays using cell extracts have demonstrated that Hsp90 and Hsp90 co‐chaperones enhance the loading of miRNAs and ...

RNA silencing processes are widespread in almost all eukaryotic organisms. They have various functions including genome protection, and the control of gene expression, development and heterochromatin formation. RNA interference (RNAi) is the post-transcriptional destruction of RNA, which is mediated by a ribonucleoprotein complex that contains, among several components, RNA helicases and Argonaute proteins. RNAi is functional in trypanosomes, protozoan parasites that separated very early from the main eukaryotic lineage and exhibit several intriguing features in terms of the control of gene expression. In this report, we investigated the functions of RNAi in Trypanosoma brucei. By searching through genome databases, novel Argonaute-like proteins were identified in several protozoa that belong to the kinetoplastid order, a group of organisms that diverged early from the main eukaryotic lineage. T. brucei possesses two Argonaute-like genes termed TbAGO1 and TbPWI1. Dual transient transfection assays

Homeostatic control of Argonaute stability by microRNA availability. - Oxford NeuroscienceHomeostatic control of Argonaute stability by microRNA availability. - Oxford Neuroscience
Homeostatic mechanisms regulate the abundance of several components in small-RNA pathways. We used Drosophila and mammalian systems to demonstrate a conserved homeostatic system in which the status of miRNA biogenesis controls Argonaute protein stability. Clonal analyses of multiple mutants of core Drosophila miRNA factors revealed that stability of the miRNA effector AGO1 is dependent on miRNA biogenesis. Reciprocally, ectopic transcription of miRNAs within in vivo clones induced accumulation of AGO1, as did genetic interference with the ubiquitin-proteasome system. In mouse cells, we found that the stability of Ago2 declined in Dicer-knockout cells and was rescued by proteasome blockade or introduction of either Dicer plasmid or Dicer-independent miRNA constructs. Notably, Dicer-dependent miRNA constructs generated pre-miRNAs that bound Ago2 but did not rescue Ago2 stability. We conclude that Argonaute levels are finely tuned by cellular availability of mature miRNAs and the ubiquitin-proteasome

Argonautes: A big turn-off for proteinsArgonautes: A big turn-off for proteins
The team set out to characterize Argonautes first using computers to compare their shapes and structures with other proteins. They found striking similarities between Argonaute structures and proteins that happened to exhibit a particular kind of cooperative binding known as allostery.. Allostery is a condition in which the binding of one molecule stimulates the binding of a second.. By chopping up Argonaute proteins from fruit flies and testing each piece individually, the team showed that allostery stimulated tenfold the binding of the Argonaute and miRNA complex to messenger RNA. The scientists speculate that as a result of being bound, the messenger RNA was prevented from doing its job of delivering a genes instructions to the ribosome that translates them and manufactures proteins. These studies provide new insights into Argonaute protein function, motivating the next series of questions in the field.. MicroRNAs are all the rage, Green says. Suddenly, in the last 10 years, theres ...

Researchers at the Whitehead Institute and Memorial Sloan-Kettering Cancer Center have defined and analyzed the crystal structure of a yeast Argonaute protein bound to RNA. This complex plays a key role in the RNA interference (RNAi) pathway that silences gene expression. Describing the molecular structure of a eukaryotic Argonaute protein has been a goal of the RNAi field for close to a decade. You can learn a lot from biochemical experiments, but to more fully understand a protein like Argonaute, its useful to know where all of the atoms are and which amino acids are playing important roles, says Whitehead Institute Member Dr. David Bartel, who is also an MIT professor of biology and a Howard Hughes Medical Institute (HHMI) investigator. Learning the Argonaute crystal structure is an important step in understanding the RNAi biochemical pathway and will be the basis for many future experiments. The yeast Argonaute structure is described in the June 21, 2012 issue of Nature. In humans and ...

RNA interference (RNAi) is a critical mechanism in cells. Many lifeforms use it to control gene expression and the functions linked to these genes.. RNAi works by turning off genes so that the latter cannot activate and sustain the processes associated with it. The process is called gene silencing.. An earlier study conducted in Jins laboratory revealed that one of the 10 Argonaute proteins got produced in higher numbers during bacterial infections. This protein bolstered the immune response of the plant against the disease. The higher its levels, the stronger the immunity of the plant.. However, increasing the Argonaute protein levels did have a drawback. The energy that went into the growth of the plant got diverted to the immune system. As a result, plants with high levels of the protein might end up stunted in size. In essence, the plant traded long-term growth for short-term survival against potentially lethal diseases.. During normal conditions, the Argonaute protein and its small RNAs ...

Argonaute (AGO) proteins form the core of the RNA-induced silencing complex, a central component of the smRNA machinery. Although reported from several plant species, little is known about their evolution. Moreover, these genes have not yet been cloned from the ecological model plant, Nicotiana attenuata, in which the smRNA machinery is known to mediate important ecological traits. Here, we not only identify 11 AGOs in N. attenuata, we further annotate 133 genes in 17 plant species, previously not annotated in the Phytozome database, to increase the number of plant AGOs to 263 genes from 37 plant species. We report the phylogenetic classification, expansion, and diversification of AGOs in the plant kingdom, which resulted in the following hypothesis about their evolutionary history: an ancestral AGO underwent duplication events after the divergence of unicellular green algae, giving rise to four major classes with subsequent gains/losses during the radiation of higher plants, resulting in the large

The Drosophila piRNA pathway provides an RNA-based immune system that defends the germline genome against selfish genetic elements. Two inter-related branches of the piRNA system exist: somatic cells that support oogenesis only employ Piwi, whereas germ cells utilize a more elaborated pathway centered on the three gonad-specific Argonaute proteins Piwi, Aubergine, and Argonaute3. While several key factors of each branch have been identified, our current knowledge is insufficient to explain the complex workings of the piRNA machinery. Here, we report a reverse genetic screen spanning the ovarian transcriptome in an attempt to uncover the full repertoire of genes required for piRNA-mediated transposon silencing in the female germline. Our screen reveals new key factors of piRNA-mediated transposon silencing, including the novel piRNA biogenesis factors, CG2183 (GASZ) and Deadlock. Last, our data uncovers a previously unanticipated set of factors preferentially required for repression of different

RNA interference (RNAi) is a post-transcriptional gene-silencing process that occurs in many eukaryotic organisms upon intracellular exposure to double-stranded RNA. Argonaute 2 (Ago2) protein is the catalytic engine of mammalian RNAi. It contains a PIWI domain that is structurally related to RNases H and possibly shares with them a two-metal-ion catalysis mechanism. Here we describe the expression in E. coli of mouse Ago2 and testing of its enzymatic activity in a RISC assay, i.e., for the ability to cleave a target RNA in a single position specified by a complementary small interfering RNA (siRNA). The results show that the enzyme can load the siRNA and cleave the complementary RNA in absence of other cellular factors, as described for human Ago2. It was also found that mutation of Arg669, a residue previously proposed to be involved in substrate and/or B metal ion binding, doesnt affect the enzymatic activity, suggesting that this residue doesnt belong to the active site.

We here ask whether piwi/piRNAs are also expressed and have functional roles in the mammalian brain. Large-scale RNA sequencing and subsequent analysis of protein expression revealed the presence in brain of several piRNA biogenesis factors including a mouse piwi (Mili), as well as small RNAs, albeit at low levels, resembling conserved piRNAs in mouse testes [primarily LINE1 (long interspersed nuclear element1) retrotransposonderived]. Despite the ...

AGO1 mRNA contains a miR168 complementarity site that is cleaved through the slicer activity of the AGO1 protein (Vaucheret et al, 2004; Baumberger & Baulcombe, 2005; Qi et al, 2005). As transgene‐derived uncapped and unpolyadenylated RNAs have been shown to activate cosuppression (Gazzani et al, 2004; Luo & Chen, 2007), it is possible that miR168‐guided cleavage of AGO1 mRNA, which produces uncapped and unpolyadenylated cleavage fragments, contributes to the hyper‐susceptibility of AGO1 to cosuppression. To test this possibility, we engineered two constructs: pAGO1:4m‐AGO1‐GUS and pAGO1:Δ168‐AGO1‐GUS. The pAGO1:4m‐AGO1‐GUS construct contains the same sequence as pAGO1:168‐AGO1‐GUS but has silent mutations that create four additional mismatches between AGO1 mRNA and miR168, and render AGO1 resistant to miR168 regulation (Vaucheret et al, 2004). The pAGO1:Δ168‐AGO1‐GUS construct is expressed from the 1.5 kb AGO1 promoter and consists of the 5′ 387 nt of AGO1 mRNA ...

piRNAs also serve while manuals for post-transcriptional repression (PTGS) of TEs. PTGS requires two additional PIWI proteins, Aub, and Ago3. The Aub/piRNA RNP complicated focuses on cytoplasmic mRNAs encoded from TEs and cleaves the mRNA by virtue of its slicer activity. Thus giving rise to fresh piRNAs called supplementary piRNAs, that are sense with regards to the canonical transposon mRNAs. These supplementary piRNAs are packed onto Ago3. The Ago3/piRNA RNP complicated focuses on precursor transcripts due to piRNA clusters. Following cleavage prompts the biogenesis of fresh piRNAs destined to Aub whose series is identical compared to that from the initiator piRNA. This loop of amplification, known as the ping-pong routine, amplifies silencing-competent piRNAs (Brennecke et al., 2007). Acting together, both of these mechanisms, PTGS and TGS, firmly repress TE transposition in the germ line and become guardians of genome integrity therefore. Interestingly, because the pool of piRNAs stated in ...

New RNA-Based Therapeutic Strategies for Controlling Gene Expression - Healthcanal.com : Healthcanal.comNew RNA-Based Therapeutic Strategies for Controlling Gene Expression - Healthcanal.com : Healthcanal.com
A comprehensive review article in Nucleic Acid Therapeutics, a peer-reviewed journal published by Mary Ann Liebert, Inc., details these advances.. Short strands of nucleic acids, called small RNAs, can be used for targeted gene silencing, making them attractive drug candidates. These small RNAs block gene expression through multiple RNA interference (RNAi) pathways, including two newly discovered pathways in which small RNAs bind to Argonaute proteins or other forms of RNA present in the cell nucleus, such as long non-coding RNAs and pre-mRNA.. Keith T. Gagnon, PhD, and David R. Corey, PhD, University of Texas Southwestern Medical Center, in Dallas, review common features shared by RNAi pathways for controlling gene expression and focus in detail on the potential for Argonaute-RNA complexes in gene regulation and other exciting new options for targeting emerging forms of non-coding RNAs and pre-mRNAs in the article Argonaute and the Nuclear RNAs: New Pathways for RNA-Mediated Control of Gene ...

Recurrent and recent selective sweeps in the piRNA pathway by Alfred Simkin, Alex Wong et al.Recurrent and recent selective sweeps in the piRNA pathway by Alfred Simkin, Alex Wong et al.
Uncontrolled transposable element (TE) insertions and excisions can cause chromosome breaks and mutations with dramatic deleterious effects. The PIWI interacting RNA (piRNA) pathway functions as an adaptive TE silencing system during germline development. Several essential piRNA pathway proteins appear to be rapidly evolving, suggesting that TEs and the silencing machinery may be engaged in a classical evolutionary arms race. Using a variety of molecular evolutionary and population genetic approaches, we find that the piRNA pathway genes rhino, krimper, and aubergine show patterns suggestive of extensive recurrent positive selection across Drosophila species. We speculate that selection on these proteins reflects crucial roles in silencing unfamiliar elements during vertical and horizontal transmission of TEs into naive populations and species, respectively.

RNA interference (RNAi) is a mechanism of gene regulation directed by Argonaute (AGO) proteins in conjunction with their sequence-specific small RNA cofactors. A multitude of distinct AGO-mediated regulatory modules have been identified in plants, fungi, and animals (1). In all of these pathways, base pair interactions between the small RNA and a target molecule provide specificity, whereas the AGO protein, which contains a conserved nuclease domain, can direct silencing through target cleavage or through recruitment of transcriptional or posttranscriptional regulators.. AGO pathways can be triggered by natural or exogenous sources of double-stranded (ds)RNA. The Dicer family of RNase III-related enzymes processes dsRNA into small RNAs of 20-25 nucleotides (nt) in length (2). For example, micro (mi)RNAs are processed from genomically encoded hairpins and mediate AGO-dependent silencing at the posttranscriptional level (3-5). Short interfering (si)RNAs are processed from both endogenous and ...

For the Perfect Eggs, Roundworms Use Small RNAsFor the Perfect Eggs, Roundworms Use Small RNAs
Eggs differ from other growing cells, where nutrients are used to build up cell mass before division occurs, said Arshad Desai, PhD, professor at UC San Diego School of Medicine and member of Ludwig Cancer Researchs San Diego branch. A frog egg, for example, makes about 3,000 cells by simply dividing into smaller and smaller cells, without growth. We were interested in understanding how eggs are able to do this.. Adding to the growing body of knowledge on small RNAs and how they influence cellular function, this study shows that small RNAs work together with an enzyme known as an Argonaute to help create the perfect C. elegans egg. The researchers based their study on earlier work showing that a specific Argonaute protein called CSR-1 affects chromosome distribution in the first division of the embryo that occurs after the egg is fertilized.. A prior study had suggested that CSR-1 influences cell division by helping to define centromeres -specialized regions on chromosome that help ...

The Piwi-piRNA Pathway Provides an Adaptive Defense in the Transposon Arms Race | ScienceThe Piwi-piRNA Pathway Provides an Adaptive Defense in the Transposon Arms Race | Science
Increasingly complex networks of small RNAs act through RNA-interference (RNAi) pathways to regulate gene expression, to mediate antiviral responses, to organize chromosomal domains, and to restrain the spread of selfish genetic elements. Historically, RNAi has been defined as a response to double-stranded RNA. However, some small RNA species may not arise from double-stranded RNA precursors. Yet, like microRNAs and small interfering RNAs, such species guide Argonaute proteins to silencing targets through complementary base-pairing. Silencing can be achieved by corecruitment of accessory factors or through the activity of Argonaute itself, which often has endonucleolytic activity. As a specific and adaptive regulatory system, RNAi is used throughout eukarya, which indicates a long evolutionary history. A likely function of RNAi throughout that history is to protect the genome from both pathogenic and parasitic invaders.. ...

Things I learned from this paper and the associated preview include: You can predict whether an Argonaute protein will have RNA cleavage activity based on the conservation of three amino acid residues (two aspartic acids and a hisitidine); in an uncommon twist, humans actually have less of a protein class than other organisms, 8 AGOs as opposed to 27 in worms and 10 in mustard plants (flies have 5, so we are still superior to flies), ~50 in the Argonautika; multiple RNAi (endo- and exo-) pathways feed into the second (SAGO) step in the worm such that the availability of SAGOs can be a limiting factor, and increasing or decreasing the activity of one of the competing pathways can affect the efficiency of the other; worms have an endo-RNAi pathway that is somehow distinguishable from their miRNA pathway, though Im not sure what the distinction is just yet. My understanding was that I could call endogenously produced small interfering RNAs microRNAs. From their model, it looks like the endo-RNAi ...

One school of thought suspected that Hsp-90 prevents the display of random abnormalities by suppressing the activities of jumping genes that can relocate to other areas of the genome and cause mutations. However, the Yale researchers report that their work with flies shows that a type of small RNA called Piwi-interacting RNA, or piRNA, acts in concert with Hsp-90 and another molecule to prevent both the creation of variants and the activation of existing genetic variants. Genes do play a role in protecting against harmful variations but probably work through actions of the molecules piRNA and Hsp-90 ...

Aedes aegypti Piwi4 is a noncanonical PIWI protein involved in antiviral responses - Enlighten: PublicationsAedes aegypti Piwi4 is a noncanonical PIWI protein involved in antiviral responses - Enlighten: Publications
The small interfering RNA (siRNA) pathway is a major antiviral response in mosquitoes; however, another RNA interference pathway, the PIWI-interacting RNA (piRNA) pathway, has been suggested to be antiviral in mosquitoes. Piwi4 has been reported to be a key mediator of this response in mosquitoes, but it is not involved in the production of virus-specific piRNAs. Here, we show that Piwi4 associates with members of the antiviral exogenous siRNA pathway (Ago2 and Dcr2), as well as with proteins of the piRNA pathway (Ago3, Piwi5, and Piwi6) in an Aedes aegypti-derived cell line, Aag2. Analysis of small RNAs captured by Piwi4 revealed that it is predominantly associated with virus-specific siRNAs in Semliki Forest virus-infected cells and, to a lesser extent, with viral piRNAs. By using a Dcr2 knockout cell line, we showed directly that Ago2 lost its antiviral activity, as it was no longer bound to siRNAs, but Piwi4 retained its antiviral activity in the absence of the siRNA pathway. These results ...

It has been demonstrated that passenger strand cleavage is important for the activation of RNA-induced silencing complex (RISC), which is a crucial step for siRNA-mediated gene silencing. Herein, we report that isonucleotide (isoNA) modification around the cleavage site of the passenger strand would affect the in vitro potency of modified siRNAs by altering the motion pattern of the Ago2-PAZ domain. According to western blotting, q-PCR and antiviral test results, we proved that D-isonucleotide (isoNA) modification at the position 8 of the passenger strand (siMek1-S08D), which is adjacent to the cleavage site, markedly improved the in vitro potency of the modified siRNA, whereas siRNAs with D-isoNA incorporation at position 9 (siMek1-S09D) or L-isoNA incorporation at positions 8 and 9 (siMek1-S08L, siMek1-S09L) displayed lower activity compared to native siRNA. Kinetics evaluation of passenger strand cleavage induced by T. thermophilus Ago (Tt-Ago) showed that D-isoNA modification at position 8 ...

Welcome to The Visible EmbryoWelcome to The Visible Embryo
In gonadal tissues, the Piwi-interacting (piRNA) pathway preserves genomic integrity by employing 23 29 nucleotide (nt) small RNAs complexed with argonaute proteins to suppress parasitic mobile sequences of DNA called transposable elements (TEs). Although recent evidence suggests that the piRNA pathway may be present in select somatic cells outside the gonads, the role of a non-gonadal somatic piRNA pathway is not well characterized. Here we report a functional somatic piRNA pathway in the adult Drosophila fat body including the presence of the piRNA effector protein Piwi and canonical 23 29 nt long TE-mapping piRNAs. The piwi mutants exhibit depletion of fat body piRNAs, increased TE mobilization, increased levels of DNA damage and reduced lipid stores. These mutants are starvation sensitive, immunologically compromised and short-lived, all phenotypes associated with compromised fat body function. These findings demonstrate the presence of a functional non-gonadal somatic piRNA pathway in the ...

May bind to short RNAs such as microRNAs (miRNAs) or short interfering RNAs (siRNAs), and represses the translation of mRNAs which are complementary to them (By similarity). Plays a role in the maintenance of the indeterminate state of the stem cells in the shoot apical meristem (SAM). Regulates leaf formation through vascular development and may be involved in determining the central domain of the leaf founder region.

Argonaute 2 in dopamine 2 receptor-expressing neurons regulates cocaine addiction | JEMArgonaute 2 in dopamine 2 receptor-expressing neurons regulates cocaine addiction | JEM
The ability of neurons to adapt to environmental signals and to memorize novel experiences determines the individual patterns of human and animal behavior. In turn, the individual differences in environmental adaptation and behavior depend on changes in gene expression. The fine-tuning of gene expression could be achieved at different levels, including regulation by microRNAs (miRNAs). miRNAs are small, noncoding RNAs that have the ability to negatively control messenger RNA (mRNA) levels or mRNA translation of their target genes (He and Hannon, 2004). These miRNA functions are executed by the multiprotein RNA-induced silencing complex (RISC). At the core of RISC are the miRNA-generating enzyme Dicer (Hutvágner et al., 2001) and the Argonaute (Ago) proteins that bind miRNAs (Lingel et al., 2003; Song et al., 2003; Yan et al., 2003) and mediate miRNA-dependent mRNA decay or translational suppression (Hammond et al., 2001). The human and mouse genome carry four independent Ago genes that encode ...

Author Summary Toxoplasma gondii is an important human parasite that causes life-threatening diseases in developing fetuses and in immunocompromised individuals, especially AIDS and transplant patients. Curiously, the Toxoplasma genome is deprived of most of the basic transcription factors that regulate gene expression in other eukaryotic cells. Therefore, alternative strategies must exist to modulate the many phases of the Toxoplasma complex life cycle that includes invasion of several hosts. Here, we investigate one of these strategies, by studying the repertoire of Toxoplasma silencing small RNAs (sRNAs). In eukaryotes, most of these regulatory molecules, 20-30nt-long, are produced by members of the Dicer RNase-III family, and exert their various functions through ubiquitous proteins called Argonaute (Ago). The surprising diversity of the Toxoplasma sRNAome uncovered in our study is consistent with those molecules exerting key functions during the parasites life cycle, including, possibly, during

It has been more than a decade since scientists realized that microRNAs (miRNAs) and Piwi-interacting RNA (piRNAs) are not mere oddities invented by worms and flies to regulate gene expression at epigenetic and post-transcriptional levels. Rather, many of these 21-31-nucleotide-short RNAs function in invertebrates and vertebrates alike and some of them are highly conserved. In mammals, miRNAs are thought to inhibit gene expression by targeting mRNA stability and translation, while piRNAs suppress retrotransposons primarily in germ line cells. More recently, they have been joined in the limelight by long non-coding (lnc) RNAs, including long intergenic non-coding RNAs (lincRNAs). lincRNAs affect gene expression by a variety of means including RNA, DNA, and protein binding. Nevertheless, the mechanisms whereby non-coding RNAs regulate ...

Work in the Green Lab is centered on the ribosome. The overall fidelity of protein synthesis appears to be limited by the action of the ribosome, which is the two-subunit macromolecular machine responsible for decoding and translating messenger RNAs (mRNAs) into protein in all organisms. Our work is divided into four general project areas. The longest-standing research area concerns the interactions of eubacterial ribosomes and release factors. The goal is to understand the mechanism of action of release factors on the ribosome. A second research area involves biochemical and structure/function studies of the miRNA pathway, particularly the mechanism of action of the Argonaute proteins and their interacting factors. A third area of work in the lab is centered around regulation of eukaryotic translation, specifically in understanding the mechanism behind various mRNA quality control pathways and the interactions of proteins therein, as well as with the ribosome.

MicroRNAs (miRNAs) are a class of small RNAs (18-22 nt) that post transcriptionally regulate gene expression by binding to complementary sequences on target mRNAs, resulting in translational repression or target degradation and gene silencing. As aberrant expression of miRNAs is implicated in important diseases including cancer miRNA-based therapies are under intensive investigation. We optimized strategies to stably or conditionally generate miRNA inhibitors for a continuous block of miRNA activity that allows for probing miRNA function in long-term cell culture experiments, cancer xenografts, 3D tissue models and for in vivo studies with transgenic organisms.

doi:10.1038/nmeth.2489. Authors: William H Majoros, Parawee Lekprasert, Neelanjan Mukherjee, Rebecca L Skalsky, David L Corcoran, Bryan R Cullen & Uwe Ohler. High-throughput sequencing has opened numerous possibilities for the identification of regulatory RNA-binding events. Cross-linking and immunoprecipitation of Argonaute proteins can pinpoint a microRNA (miRNA) target site within tens of bases but leaves the identity of the miRNA unresolved. A flexible computational framework, microMUMMIE, integrates sequence with cross-linking features and reliably identifies the miRNA family involved in each binding event. It considerably outperforms sequence-only approaches and quantifies the prevalence of noncanonical binding modes. ...

T cell activation induces proteasomal degradation of Argonaute and rapid remodeling of the microRNA repertoire | JEMT cell activation induces proteasomal degradation of Argonaute and rapid remodeling of the microRNA repertoire | JEM
Naive T cells that encounter their cognate antigen dramatically remodel their gene expression program as they proliferate and acquire effector functions. The data presented here demonstrate that these cells also actively reset their miRNA repertoire. Activation-induced global posttranscriptional down-regulation of mature miRNAs allows concurrent changes in pri-miRNA gene transcription to rapidly establish a new pattern of miRNA expression in effector cells. Ago1 and Ago2, which bind miRNAs in the miRISC and mediate target mRNA repression, are also down-regulated during T cell activation in a process of ubiquitination and proteasomal degradation. This degradation depends on intact PI3K/mTOR signaling and continuous transcription and translation. Ago2 is a limiting factor for miRNA expression in T cells, with the abundance of a large panel of miRNAs reduced by 30% for each disrupted allele of Ago2. Collectively, our data support a model in which TCR engagement leads to down-regulation of Ago ...

DSpace@MIT: Discovery of miRNA-regulated processes in mammalian development[email protected]: Discovery of miRNA-regulated processes in mammalian development
The genomes of plants and animals encode hundreds of non-coding ~22nt RNAs termed microRNAs (miRNAs). These RNAs guide the sequence-specific inhibition of translation and destabilization of mRNA targets through short (6-7 nucleotide) stretches of complementarity between the 5 end of the miRNA (seed region) and the 3 untranslated region (UTR) of the targeted mRNA. Computational estimates based on prediction of conserved seed matches in 3UTRs suggest that over half of genes in mammalian genomes are miRNA-regulated. Many miRNAs are also ubiquitously expressed in a variety of embryonic and adult tissues. Given these observations, we have sought to address the challenge of determining which cellular and biological processes that miRNAs might regulate in different cell types and tissues. First, we have developed methods to isolate candidate miRNA-targeted mRNAs by immunoprecipitation of Ago2 in the miRNA effector complex (miRNP). In one purification method, the Ago2-bound mRNAs are identified by ...

RNA binding proteins (RBPs) can regulate the stability and/or translatability of messengerRNAs (mRNAs) throughinteractions with their 30-untranslated regions. However, individual mRNAs may be regulated simultaneously or successivelyby more than one RBP, as well as by Argonaute (AGO)-bound miRNAs; the coordination of these various influenceson an individual mRNA is therefore complex and not well studied. In this report we examine the roles of two RBPs thatbind to AU-rich elements (ARE) - AUF1 and HuR - in the stability and translation of cyclin D1 (Ccnd1) mRNA in ratmyoblasts transiting the G phase of the cell cycle, and their interactions with miRNAs. Knockdown (KD) of AUF1 resultedin (1) transient upregulation of the mRNA level as well as an advancement of translation onset time (TOT) from 6 to 5 hpost-serum addition, (2) loss of miRNA loading on AGO1 and AGO2 and (3) reduction in the level of AGO-1 and AGO-2bound mRNA. In contrast, KD of HuR had no effect on the mRNA level, or on the AGO-mRNA ...

Present and not reporting for duty: dsRNAi in mammalian cells | The EMBO JournalPresent and not reporting for duty: dsRNAi in mammalian cells | The EMBO Journal
RNA interference (RNAi) is a mechanism conserved in most eukaryotes that enables sequence‐specific gene silencing via the use of small RNAs 22-30 nt in length. As an anti‐viral defense system, RNAi operates by sensing and fragmenting viral dsRNA through the action a Dicer RNase. The resulting small interfering RNAs (siRNAs) then guide Argonaute (Ago) effector proteins in an RNA‐induced silencing complex (RISC) to cleave target RNA sequences bearing siRNA complementarity. This core system to sense and process dsRNA via Dicer into siRNAs that guide Agos is the hallmark of dsRNAi and is distinct but related to the role of these proteins in gene regulation via microRNAs (miRNAs) (tenOever, 2016). In plants and invertebrates, dsRNAi plays a critical role in suppressing viral accumulation and provides a systemic immune response (tenOever, 2016). Attesting to the power of this nucleic acid‐based immune system, numerous plants and invertebrate viruses have evolved viral suppressors of RNAi ...

Odkritje in delovanje kompleksa RISC - Wiki FKKTOdkritje in delovanje kompleksa RISC - Wiki FKKT
Pri obeh modelih ostaja protismiselna veriga siRNA vezana na AGO2. Na to verigo se lahko s komplemetarnimi bazami veže molekula mRNA. Nekatere raziskave potrjujejo, da ni nujno, da se molekula mRNA veže s popolnim ujemanjem baznih parov, medtem ko druge trdijo da mora biti to ujamanje nujno popolno, ker drugače nadaljni procesi ne stečejo. Do leta 2004 niso popolnoma razumeli zakaj se geni zapisani v mRNA ne izražajo po tem, ko je tudi mRNA vezana v kompleks RISC. Nato pa so Dianne S. Schwar in sodelavci pokazali, da ima RISC endonukleazno aktivnost, ter tudi, da le-ta zavisi od Mg2+ ionov. Po tem odkritju je postalo jasno, da po tem, ko se mRNA veže z siRNA RISC, deluje v smer njene cepitve in posledičnega uničenja. S tem se seveda »izgubijo« tudi geni katere kodira. Kasnejše raziskave pa so pokazale, da ni nujno, da RISC utiša gene popolnoma, ampak jih lahko utiša tudi samo za nek časovni interval. Do tega pride v tako imenovanih GW telescih oziroma citoplazemskih (P) faktorjih. ...
