Lead (Pb) is one of the most serious environmental pollutants. The aquatic fern Salvinia minima Baker is capable to hyper-accumulate Pb in their tissues. However, the molecular mechanisms involved in its Pb accumulation and tolerance capacity are not fully understood. In order to investigate the molecular mechanisms that are activated by S. minima in response to Pb, we constructed a suppression subtractive hybridization library (SSH) in response to an exposure to 40μM of Pb(NO3)2 for 12h. 365 lead-related differentially expressed sequences tags (ESTs) were isolated and sequenced...

The aim of this systematic review and meta-analysis was to assess the effect of exercise in population-based interventions to prevent low back pain (LBP) and associated disability. Comprehensive literature searches were conducted in multiple databases including PubMed, Embase, and Cochrane Library from their inception through June 2017. Thirteen randomized controlled trials and three non-randomized controlled trials qualified for meta-analyses. Exercise alone reduced the risk of LBP by 33% (risk ratio = 0...

Drought is a major abiotic stress impeding the yield of cereal crops globally. Particularly in Mediterranean environments, water becomes a limiting factor during the reproductive developmental stage, causing yield losses. The wild progenitor of cultivated barley Hordeum vulgare ssp spontaneum (Hsp) is a potentially useful source of drought tolerance alleles. Wild barley introgression lines like the S42IL library may facilitate the introduction of favorable exotic alleles into breeding material. The complete set of 83 S42ILs was genotyped with the barley 9k iSelect platform in order to complete genetic information obtained in previous studies...

Studies in the last decade have revealed a complex and dynamic variety of pre-mRNA cleavage and polyadenylation reactions. mRNAs with long 3' untranslated regions (UTRs) are generated in differentiated cells whereas proliferating cells preferentially express transcripts with short 3'UTRs. We describe the A-seq protocol, now at its second version, which was developed to map polyadenylation sites genome-wide and study the regulation of pre-mRNA 3' end processing. Also this current protocol takes advantage of the polyadenylate (poly(A)) tails that are added during the biogenesis of most mammalian mRNAs to enrich for fully processed mRNAs...

BACKGROUND: Human immunodeficiency virus-infected individuals (HIVIIs) have a higher incidence of head and neck squamous cell carcinoma (HNSCC), and clinical and histopathological differences have been observed in their tumors in comparison with those of HNSCC patients without a human immunodeficiency virus (HIV) infection. The reasons for these differences are not clear, and molecular differences between HIV-related HNSCC and non-HIV-related HNSCC may exist. This study compared the mutational patterns of HIV-related HNSCC and non-HIV-related HNSCC...

Gang Jia, Wenjing Li, Meina Fan, Ru Yu, Yang Xu, Liwei Geng, Jiedao Zhang, Changxiang Zhu, Hongmei Liu
HVT063, an RNA-binding protein encoded by turkey herpesvirus, has been shown previously to suppress RNA silencing. Here, a scanning library produced by pentapeptide-insertion scanning mutagenesis was used to identify key residues associated with its RNA silencing suppressor (RSS) activity. Forty-two in-frame insertion mutants of HVT063 protein were evaluated for their RSS activity using the dual-luciferase transient expressing assay system. Sixteen mutations resulted in a loss of RSS activity, 20 mutations resulted in decreased RSS activity, and six mutations exhibited high RSS activity similar to wild-type HVT063...

Identifying and characterizing highly accessible chromatin regions assists in determining the location of genomic regulatory elements and understanding transcriptional regulation. In this chapter, we describe an approach to map accessible chromatin features in plants using the Assay for Transposase-Accessible Chromatin, combined with high-throughput sequencing (ATAC-seq), which was originally developed for cultured animal cells. This technique utilizes a hyperactive Tn5 transposase to cause DNA cleavage and simultaneous insertion of sequencing adapters into open chromatin regions of the input nuclei...

Bisulfite sequencing (BS-seq) enables the detection of DNA methylation at cytosine residues (5mC) at single-nucleotide resolution. For many applications, a limiting factor of conventional BS-seq protocols is the high amount of DNA required, since the treatment with bisulfite causes severe DNA fragmentation. Here, we describe a post-bisulfite tagging method that accounts for this problem. Illumina-compatible BS-seq libraries can be obtained from as little as five single haploid maize cells, enabling whole genome BS-seq (WGBS) for the generation of genome-wide, cell-type specific DNA methylation profiles...

This study has designed and implemented a library of hetero-nanostructured catalysts, denoted as Pd@Nb2O5, comprised of size-controlled Pd nanocrystals interfaced with Nb2O5 nanorods. This study also demonstrates that the catalytic activity and selectivity of CO2 reduction to CO and CH4 products can be systematically tailored by varying the size of the Pd nanocrystals supported on the Nb2O5 nanorods. Using large Pd nanocrystals, this study achieves CO and CH4 production rates as high as 0.75 and 0.11 mol h(-1) gPd(-1), respectively...

Profiling of microbial community composition is frequently performed by partial 16S rRNA gene sequencing on benchtop platforms following PCR amplification of specific hypervariable regions within this gene. Accuracy and reproducibility of this strategy are two key parameters to consider, which may be influenced during all processes from sample collection and storage, through DNA extraction and PCR based library preparation to the final sequencing. In order to evaluate both the reproducibility and accuracy of 16S rRNA gene based microbial profiling using the Ion Torrent PGM platform, we prepared libraries and performed sequencing of a well-defined and validated 20-member bacterial DNA mock community on five separate occasions and compared results with the expected even distribution...

The tea plant (Camellia sinensis L.) is vulnerable to the geometrid Ectropis oblique; although microRNAs (miRNAs) are important for plant growth, development and stress response, the function of miRNAs in the response of C. sinensis to stress from E. oblique is unclear. To identify E. oblique stress-responsive miRNAs and their target genes in tea plant, three small RNA libraries were constructed from leaves subjected to mechanical wounding (MW), geometrid attack (GA) and from healthy control (CK) leaves. Using high-throughput sequencing, 130 known miRNAs and 512 novel miRNAs were identified; of these, differential expression under GA stress was observed for 36 known and 139 novel miRNAs...

Metalloenzyme arginase is a therapeutically relevant target associated with tumor growth. To fight cancer immunosuppression, arginase activity can be modulated by small chemical inhibitors binding to its catalytic center. To better understand molecular mechanisms of arginase inhibition, a careful computer-aided mechanistic structural investigation of this enzyme was conducted. Using molecular dynamics (MD) simulations in the microsecond range, key regions of the protein active site were identified and their flexibility was evaluated and compared...

A longstanding goal of synthetic biology has been the programmable control of cellular functions. Central to this is the creation of versatile regulatory toolsets that allow for programmable control of gene expression. Of the many regulatory molecules available, RNA regulators offer the intriguing possibility of de novo design-allowing for the bottom-up molecular-level design of genetic control systems. Here we present a computational design approach for the creation of a bacterial regulator called Small Transcription Activating RNAs (STARs) and create a library of high-performing and orthogonal STARs that achieve up to ~ 9000-fold gene activation...

REVIEW
Yoshikazu Nakamura
Therapeutic molecules can be classified as low-, middle- and high-molecular weight drugs depending on their molecular masses. Antibodies represent high-molecular weight drugs and their clinical applications have been developing rapidly. Aptamers, on the other hand, are middle-molecular weight molecules that are short, single-stranded nucleic acid sequences that are selected in vitro from large oligonucleotide libraries based on their high affinity to a target molecule. Hence, aptamers can be thought of as a nucleic acid analog to antibodies...
