Zhong, Dongping and Bernhardt, Thorsten M. Zhong, Dongping and Zewail, Ahmed H. Chemical Physics Letters, The assembled transcripts were then translated in all six frames and compared to proteins in NCBI's non-redundant NR and to the Gene Ontology GO protein sequence databases, resulting in 15, matches to 11, proteins in NR and 13, matches to 8, proteins in GO. Searching the database for transcripts of genes homologous to those thought to be involved in the innate immune responses of vertebrates and other invertebrates yielded a set of nearly one hundred evolutionarily conserved sequences, representing all known pathways involved in these important functions.
Conclusions: The sequences obtained for Hirudo transcripts represent the first major database of genes expressed in this important model system. Phylogenetic comparisons of putative Hirudo innate immune response genes present within the Hirudo transcriptome database herein described show a strong resemblance to the corresponding mammalian genes, indicating that this important physiological response may have older origins than what has been previously proposed. Desulfotomaculum reducens strain MI-1 is one of the few cultured representatives of that group with a complete genome sequence available.
The metabolic versatility of this organism is reflected in the presence of genes encoding for the oxidation of various electron donors, including three- and four-carbon fatty acids and alcohols. Synteny in genes involved in sulfate reduction across all four sequenced Gram-positive SRB suggests a distinct sulfate-reduction mechanism for this group of bacteria.
Based on the genomic information obtained for sulfate reduction in D. In addition, both H 2 -evolving and H 2 -consuming cytoplasmic hydrogenases were identified in the genome, pointing to potential cytoplasmic H 2 cycling in the bacterium. The mechanism of metal reduction remains unknown. MSI is a molecular imaging technique that allows for the generation of topographic 2D maps for various endogenous and some exogenous molecules without prior specification of the molecule. In this paper, we start with the premise that a region of interest ROI is given to us based on preselected morphological criteria.
Given an ROT, we develop a pipeline, first to determine mass values with distinct expression signatures, localized to the ROI, and second to identify the peptides corresponding to these mass values. To identify spatially differentiated masses, we implement a statistic that allows us to estimate, for each spectral peak, the probability that it is over- or under-expressed within the ROI versus outside.
A novel pipeline based on constructing sequence tags de novo from both original and decharged spectra and a subsequent database search is used to identify peptides. As the MSI signal and the identified peptide are only related by a single mass value, we isolate the corresponding transcript and perform a second validation via in situ hybridization of the transcript. The Hirudo CNS is capable of regenerating itself after injury, thus forming an important model system for neuropeptide identification.
The pipeline helps identify a number of novel peptides. Specifically, we identify a gene that we name HmIF4, which is a member of the intermediate filament family involved in neural development and a second novel, uncharacterized peptide. A third peptide, derived from the histone H2B, is also identified, in agreement with the previously suggested role of histone H2B in axon targeting.
In the present work, spatiotemporal changes in molecular distributions during this phenomenon are explored. Moreover, the hypothesis that neural regeneration involves some molecular factors initially employed during embryonic neural development is tested. RESULTS: Imaging mass spectrometry coupled to peptidomic and lipidomic methodologies allowed the selection of molecules whose spatiotemporal pattern of expression was of potential interest.
Through the parallel use of a classical lipidomic approach and secondary ion mass spectrometry, specific lipids, including cannabinoids, gangliosides and several other types, were detected in adult ganglia following mechanical damage to connected nerves. These observations motivated a search for possible effects of cannabinoids on neurite outgrowth.
Exposing nervous tissues to Transient Receptor Potential Vanilloid TRPV receptor agonists resulted in enhanced neurite outgrowth from a cut nerve, while exposure to antagonists blocked such outgrowth. Our data further suggest that endocannabinoids also play key roles in CNS regeneration, mediated through the activation of leech TRPVs, as a thorough search of leech genome databases failed to reveal any leech orthologs of the mammalian cannabinoid receptors but revealed putative TRPVs. In sum, our observations identify a number of lipids and proteins that may contribute to different aspects of the complex phenomenon of leech nerve regeneration, establishing an important base for future functional assays.
This study presents the first characterization of endogenous small RNAs in a diatom, Thalassiosira pseudonana. Small RNAs act as transcriptional and translational regulators, controlling specific target genes involved in various cellular functions. Diatoms are unicellular photosynthetic organisms that play major roles in environmental processes, such as food webs and global carbon fixation.
From the computational analysis of approximately , sequences in the library and over 17 million sequences in the SOLiD libraries, there exists evidence of a core set of small RNA genes including: novel microRNAs, repeat-associated short interfering RNAs, and endogenous short interfering RNAs. The diatom genome contains elements similar to plant small RNA systems, such as the RNAi machinery, a high percentage of short interfering RNAs originating from protein-coding and repetitive regions of the genome, and putative binding sites of the small RNAs occurring primarily in the coding section of the predicted targets.
The characterization of the small RNA transcriptome of T. Ataxin-7 is a component of two different transcription coactivator complexes, and recent work indicates that disease protein normal function is altered in polyglutamine neurodegeneration. Given this, we studied how ataxin-7 gene expression is regulated.
The ataxin-7 repeat and translation start site are flanked by binding sites for CTCF, a highly conserved multifunctional transcription regulator. Loss of SCAANT1 derepressed ataxin-7 sense transcription in a cis-dependent fashion and was accompanied by chromatin remodeling. Discovery of this pathway underscores the importance of altered epigenetic regulation for disease pathology at repeat loci exhibiting bidirectional transcription. DV was not detected in 19 other African Americans with iron overload who resided in Alabama. DV could explain 'classical' ferroportin hemochromatosis phenotypes in some African Americans.

Karger AG, Basel. Splicing is a cellular mechanism, which dictates eukaryotic gene expression by removing the noncoding introns and ligating the coding exons in the form of a messenger RNA molecule. Alternative splicing AS adds a major level of complexity to this mechanism and thus to the regulation of gene expression. This widespread cellular phenomenon generates multiple messenger RNA isoforms from a single gene, by utilizing alternative splice sites and promoting different exon-intron inclusions and exclusions.
AS greatly increases the coding potential of eukaryotic genomes and hence contributes to the diversity of eukaryotic proteomes. Mutations that lead to disruptions of either constitutive splicing or AS cause several diseases, among which are myotonic dystrophy and cystic fibrosis. Aberrant splicing is also well established in cancer states.
Identification of rare novel mutations associated with splice-site recognition, and splicing regulation in general, could provide further insight into genetic mechanisms of rare diseases. Here, disease relevance of aberrant splicing is reviewed, and the new methodological approach of starting from disease phenotype, employing exome sequencing and identifying rare mutations affecting splicing regulation is described. Exome sequencing has emerged as a reliable method for finding sequence variations associated with various disease states. To date, genetic studies using exome sequencing to find disease-causing mutations have focused on the discovery of nonsynonymous single nucleotide polymorphisms that alter amino acids or introduce early stop codons, or on the use of exome sequencing as a means to genotype known single nucleotide polymorphisms.
The involvement of splicing mutations in inherited diseases has received little attention and thus likely occurs more frequently than currently estimated. Studies of exome sequencing followed by molecular and bioinformatic analyses have great potential to reveal the high impact of splicing mutations underlying human disease. Standard Illumina mate-paired libraries are constructed from 3- to 5-kb DNA fragments by a blunt-end circularization.
Sequencing reads that pass through the junction of the two joined ends of a kb DNA fragment are not easy to identify and pose problems during mapping and de novo assembly. Longer read lengths increase the possibility that a read will cross the junction. To solve this problem, we developed a mate-paired protocol for use with Illumina sequencing technology that uses Cre-Lox recombination instead of blunt end circularization.
Alternate year course. As the number of our digital traces continues to grow, so does the opportunity for discovering meaningful patterns in these traces.
