Caged antisense oligodeoxynucleotides (asODNs) are synthesized by linking two ends of linear oligodeoxynucleotides using a photocleavable linker. Two of them (H30 and H40) have hairpin-like structures which show a large difference in thermal stability (delta T(m) = 17.5 degrees C and 11.6 degrees C) comparing to uncaged ones. The other three (C20, C30 and C40) without stable secondary structures have the middle 20 deoxynucleotides complementary to 40-mer RNA. All caged asODNs have restricted opening which provides control over RNA/asODN interaction. RNase H assay results showed that 40-mer RNA digestion could be photo-modulated 2- to 3-fold upon light-activation with H30, H40, C30 and C40, while with C20, RNA digestion was almost not detectable; however, photo-activation triggered > 20-fold increase of RNA digestion. And gel shift assays showed that it needed > 0.04 mu M H40 and 0.5 mu M H30 to completely bind 0.02 mu M 40-mer RNA, and for C40 and C30, it needed > 0.2 mu M and 0.5 mu M for 0.02 ...

Our visit to Wolfson hospital today to see how Chrakhan was progressing was a happy occasion. She was sitting up in bed, but still being monitored. The chest drain tube remained. Intravenous fluid was still being circulated throughout her body in order to keep her hydrated, provide medication, and give access in the case of emergency; intravenous medication acts quicker, because of its direct entry into the blood stream and hence to the target organ. The bluing cyanosis in her lips and tongue had lessened considerably. She was peripherally warm, looked comfortable, and was not in any pain at rest. The chest tube can be quite painful. Chrakhan was on three types of pain relief to keep her fairly pain free. Speaking to an ICU doctor about Chrakhans progress, he mentioned pleural fluid on the opposite site to the chest tube that needed aspirating, which will reduce the likelihood of infection. Her mother looked quite relaxed, sitting beside her daughter. Before I said goodbye I sang to her a ...

Amyotrophic lateral sclerosis (ALS) is an incurable neurodegenerative disorder affecting motoneurons. Mutations in angiogenin, encoding a member of the pancreatic RNase A superfamily, segregate with ALS. We previously demonstrated that angiogenin administration shows promise as a neuroprotective therapeutic in studies using transgenic ALS mice and primary motoneuron cultures. Its mechanism of action and target cells in the spinal cord, however, are largely unknown. Using mixed motoneuron cultures, motoneuron-like NSC34 cells, and primary astroglia cultures as model systems, we here demonstrate that angiogenin is a neuronally secreted factor that is endocytosed by astroglia and mediates neuroprotection in paracrine. We show that wild-type angiogenin acts unidirectionally to induce RNA cleavage in astroglia, while the ALS-associated K40I mutant is also secreted and endocytosed, but fails to induce RNA cleavage. Angiogenin uptake into astroglia requires heparan sulfate proteoglycans, and engages ...

MicroRNAs play an important role in abiotic stress responses in higher plants and animals, but their role in stress adaptation in algae remains unknown. In this study, the expression of identified and putative miRNAs in Chlamydomonas reinhardtii was assessed using quantitative polymerase chain reaction; some of the miRNAs (Cre-miR906-3p) were up-regulated, whereas others (Cre-miR910) were downregulated when the species was subjected to multiple abiotic stresses. With degradome sequencing data, we also identified ATP4 (the d-subunit of ATP synthase) and NCR2 (NADPH: cytochrome P450 reductase) as one of the several targets of Cre-miR906-3p and Cre-miR910, respectively. Q-PCR data indicated that ATP4, which was expressed inversely in relation to Cre-miR906-3p under stress conditions. Overexpressing of Cre-miR906-3p enhanced resistance to multiple stresses; conversely, overexpressing of ATP4 produced the opposite effect. These data of Q-PCR, degradome sequencing and adaptation of overexpressing ...

A toxin-antitoxin system is a set of two or more closely linked genes that together encode both a protein poison and a corresponding antidote. When these systems are contained on plasmids - transferable genetic elements - they ensure that only the daughter cells that inherit the plasmid survive after cell division. If the plasmid is absent in a daughter cell, the unstable antitoxin is degraded and the stable toxic protein kills the new cell; this is known as post-segregational killing (PSK). Toxin-antitoxin systems are widely distributed in prokaryotes, and organisms often have them in multiple copies. Toxin-antitoxin systems are typically classified according to how the antitoxin neutralises the toxin. In a Type I toxin-antitoxin system, the translation of messenger RNA (mRNA) that encodes the toxin is inhibited by the binding of a small non-coding RNA antitoxin to the mRNA. The protein toxin in a type II system is inhibited post-translationally by the binding of another protein ...

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 ...

Program requirements are reviewed and approved by Faculty Council and Senate. Normally, Undergraduate Certificates will be completed concurrently with an undergraduate degree program and are differentiated from a degree program by a higher GPA requirement (the 4.00 specified above is a lower limit) or a more focused selection of courses. However, direct-entry, stand-alone certificate programs are available and are primarily intended to meet the need for specific professional preparation. Such direct entry certificate programs will generally be in the nature of either career-entry or mid-career development, and candidates will normally already hold a degree or have significant post-secondary education. While most certificate programs (except for the Certificate of Proficiency) will require close to the minimum 24 credits, thereby differentiating a certificate from major requirements within a degree program, it is expected that some Professional Certificate programs will justify lower or higher ...
Recent studies have revealed that endonucleolytic cleavage is a fundamental aspect of nonsense-mediated mRNA decay in eukaryotes (Stevens et al. 2002; Gatfield and Tzaurralde 2004) and trans-translation in prokaryotes (Sunohara et al. 2004). In these cases, the presence of a stop codon somehow promotes endonucleolytic cleavages of mRNA. Similarly, RNase LS in E. coli was suggested to cleave mRNA, depending on a stop codon to accelerate mRNA degradation (Kai and Yonesaki 2002). In this study, we investigated the stop codon-dependent cleavage of T4 soc mRNA by RNase LS and found several characteristic features of the cleavage. First, any stop codon, amber, ochre, or opal, was effective for inducing cleavage at NE. Second, the initiation of translation was required for cleavage, which did not occur when the Shine-Dalgarno sequence was eliminated. Third, cleavage depending on an amber codon was significantly reduced by the presence of amber-codon-suppressing tRNA. All of these results strongly ...
Plasmon ruler RNase A cleavage assay. (A) The RNA plasmon rulers are bound to the surface of a glass flow chamber using a BSA (bovin serum albumin)-Biotin-NeutrAvidin surface chemistry. Upon addition of RNase A, the RNA tether is cleaved, and the dimer converted into a monomer. (B) Single RNA plasmon ruler cleavage trajectory (recorded at 96 Hz). (I) The plasmon ruler is first incubated in buffer containing spermidine at defined concentrations (0 -5 mM), (II) the buffer is exchanged with a 1 nM RNase A solution, causing (III) a strong drop in intensity upon RNA cleavage.

With all four features, a more negative score is associated with a more favorable site. The context score is the sum of the above scores, and the context score percentile is the percentile rank of each site compared to all sites for this miRNA family. Thus a high context score percentile (between 50 and 100) shows that a specific site is more favorable than most other sites of this miRNA. In a gene with multiple sites for one miRNA family, a total context score is calculated as the sum of context scores for the most favorable (most negative) miRNA in this family (as shown on the miRNA family pages [example]). If the context score for any of these sites is positive (unfavorable), its contribution to the total context score is 0. The "representative miRNA" is the miRNA in this family with the most favorable total context score ...

RNase L and Ire1p are members of a superfamily of regulated endoribonucleases that play essential roles in mediating diverse types of cellular stress responses. 2′-5′ oligoadenylates, produced in response to interferon treatment and viral double-stranded RNA, are necessary to activate RNase L. In contrast, unfolded proteins in the endoplasmic reticulum activate Ire1p, a transmembrane serine/threonine kinase and endoribonuclease. To probe their similarities and differences, molecular properties of wild-type and mutant forms of human RNase L and yeast Ire1p were compared. Surprisingly, RNase L and Ire1p showed mutually exclusive RNA substrate specificity and partially overlapping but not identical requirements for phylogenetically conserved amino acid residues in their nuclease domains. A functional model for RNase L was generated based on the comparative analysis with Ire1p that assigns novel roles for ankyrin repeats and kinase-like domains.. ...
The CRISPR (clustered regularly interspaced short palindromic repeats) immune system in prokaryotes uses small guide RNAs to neutralize invading viruses and plasmids. In Escherichia coli, immunity depends on a ribonucleoprotein complex called Cascade. Here we present the composition and low-resolution structure of Cascade and show how it recognizes double-stranded DNA (dsDNA) targets in a sequence-specific manner. Cascade is a 405-kDa complex comprising five functionally essential CRISPR-associated (Cas) proteins (CasA(1)B(2)C(6)D(1)E(1)) and a 61-nucleotide CRISPR RNA (crRNA) with 5-hydroxyl and 2,3-cyclic phosphate termini. The crRNA guides Cascade to dsDNA target sequences by forming base pairs with the complementary DNA strand while displacing the noncomplementary strand to form an R-loop. Cascade recognizes target DNA without consuming ATP, which suggests that continuous invader DNA surveillance takes place without energy investment. The structure of Cascade shows an unusual seahorse shape that
