Imaging mRNA with single-molecule sensitivity in live cells has become an indispensable tool for quantitatively studying RNA biology. The MS2 system has been extensively used due to its unique simplicity and sensitivity. However, the levels of the coat protein needed for consistent labeling of mRNAs limits the sensitivity and quantitation of this technology. Here, we applied fluorescence fluctu...
A novel recombinant coxsackievirus A6 (CVA6) strain was isolated during a coxsackievirus A6 outbreak in Shanghai, China, in 2013. Genomic sequence and similarity plot analysis showed that the novel CVA6 strain shared higher similarity with a recent CVA4 strain rather than the recent CVA6 strain in the 2C and 3' untranslated regions (UTRs).
The Drosophila E(spl)m4 gene contains some highly conserved motifs (such as the Brd box, GY box, K box, and CAAC motif) in its 3' untranslated region (3' UTR). It was shown to be a microRNA target gene in Drosophila and to play an important role in the regulation of neurogenesis. We identified a homologue of the E(spl)m4 gene from Bombyx mori called BmEm4 and examined the expression patterns of...
Regulatory relationships of 686 intronic miRNA and 784 intergenic miRNAs with mRNAs of 51 intronic miRNA coding genes were established. Interaction features of studied miRNAs with 5'UTR, CDS and 3'UTR of mRNA of each gene were revealed. Functional regions of mRNA were shown to be significantly heterogenous according to the number of binding sites of miRNA and to the location density of these si...
In eukaryotes, Dom34 is involved in the rescue of ribosomes that stall on mRNAs during protein synthesis. Using ribosome profiling, Guydosh and Green reveal that, in addition to rescue of ribosomes stalled on truncated mRNAs, Dom34 also recycles ribosomes that are unexpectedly found in the 3' untranslated regions of many cellular mRNAs.
The poliovirus mutant 5NC-11 has a 4-base insertion at position 70 within the 5' untranslated region and is deficient in RNA synthesis. Revertants from 5NC-11 were isolated, showing a partial recovery of wild-type levels of RNA synthesis. The 5' noncoding region of those revertants contained the mutation intact; mix-and-match experiments with the cDNA from these revertants revealed that a restr...
in 1974, the world health organization (who) established the expanded program on immunization (epi) to ensure that all children have access to routinely recommended vaccines. since then, global coverage with the four core vaccines (bacille calmette guérin vaccine [for protection against tuberculosis], diphtheria-tetanus-pertussis vaccine [dtp], polio vaccine, and measles vaccine) has increased ...
background and purpose: water is the most important limiting factor of sustainable development. poor quality of water sources and lack of appropriate management in some regions are the main reasons of water crises in the country. this study was conducted to assess water sources quality and the trend of their change in rural area of sabzevar county in a five year period. materials and methods: i...
It is a long-standing proposal that localization of maternal factors in eggs can provide the basis for pattern formation in the early embryo. The localized information can be stored as RNA, one example being Vg1 RNA, which is localized exclusively to the vegetal hemisphere of Xenopus oocytes and eggs. Localization of Vg1 mRNA is directed by a 340-nt sequence element contained within its 3' untr...
