The mechanisms of silver nanoparticle toxicity however remain unclear. We examined the effects of exposure to silver in nano bulk and ionic forms on zebrafish embryos Danio rerio using a Next Generation Sequencing approach in an Illumina platform High Throughput SuperSAGE. Significant alterations in gene expression were found for all treatments and many of the gene pathways affected most notably those associated with oxidative phosphorylation and protein synthesis overlapped strongly between the three treatments indicating similar mechanisms of toxicity for the three forms of silver studied. Changes in oxidative phosphorylation indicated a down regulation of this pathway at 24h of exposure but with a recovery at 48h. This finding was consistent with a dose dependent decrease in oxygen consumption at 24h but not at 48h following exposure to silver ions. Overall our data provide support for the hypothesis that the toxicity caused by silver nanoparticles is principally associated with bioavailable silver ions in exposed zebrafish embryos. These findings are important in the evaluation of the risk that silver particles may pose to exposed vertebrate organisms. Overall design: mRNA profiles of whole zebrafish embryos at 24 hpf and 48 hpf exposed to silver in nano bulk and ionic forms were generated by deep sequencing using HT SuperSAGE Illumina GA2. | pubmed:23758687 | Dre 48h silver ions | GSM935123 | source name:Dre 48h silver ions|strain:wild type WIK strain|tissue:whole embryos|developmental stage:48 hpf|treatment:silver ions 0.25 µg/L of silver nitrate|barcode:GCGA | Dre 48h silver ions | FASTQ/A Barcode splitter from the FASTX Toolkit http://hannonlab.cshl.edu/fastx toolkit/download.html was used to separate the samples from each lane using the 4 base barcode.

The mechanisms of silver nanoparticle toxicity however remain unclear. We examined the effects of exposure to silver in nano bulk and ionic forms on zebrafish embryos Danio rerio using a Next Generation Sequencing approach in an Illumina platform High Throughput SuperSAGE. Significant alterations in gene expression were found for all treatments and many of the gene pathways affected most notably those associated with oxidative phosphorylation and protein synthesis overlapped strongly between the three treatments indicating similar mechanisms of toxicity for the three forms of silver studied. Changes in oxidative phosphorylation indicated a down regulation of this pathway at 24h of exposure but with a recovery at 48h.

However the identity of Cap2 containing mRNAs and the function of Cap2 are unclear. Here we describe CLAM Cap Seq a method for transcriptome wide mapping and quantification of Cap2. We find that unlike other epitranscriptomic modifications Cap2 can occur on all mRNAs. Cap2 is formed through a slow continuous conversion of mRNAs from Cap1 to Cap2 as mRNAs age in the cytosol. As a result Cap2 is enriched on long lived mRNAs. We find that large increases in the abundance of Cap1 leads to activation of RIG I especially in conditions where RIG I expression is increased. The methylation of Cap1 to Cap2 markedly reduces the ability of RNAs to bind and activate RIG I. We find that the slow Cap2 methylation rate allows Cap2 to accumulate on host mRNAs yet ensures that low Cap2 levels occur on newly expressed viral RNAs.
