31947 SRR28790254 SRX24354550 SRS21112318 SRP503769 PRJNA1104180 Double stranded RNA triggers a distinct integrated stress response in the early embryo [RNA seq Ribo seq] GSE265771 Other Double stranded RNA dsRNA is associated with virus infections and is present as by products during the transcription of synthetic mRNA which has been widely used in gene gain of function studies and serves as a core component in emerging mRNA based therapies1 4. The presence of dsRNA in host cells induces an integrated stress response that functions to prevent virus replication and infection5 6. Unlike differentiated cells undifferentiated cells adopt a distinct defense strategy against RNA virus infection7 but the mechanism is unclear. We show a previously unidentified response triggered by dsRNA in the early embryo. Although dsRNA causes a global protein translation inhibition in a PKR eIF2a independent manner and leads to developmental delay and cell necrosis it also strongly induces p53 activation which then upregulates Interferon Stimulated Genes independently of interferon ligands. Importantly we demonstrate that the burst of p53 signaling dose not result in cell death but functions as a protective mechanism against deleterious translation blockage by slowing down global protein degradation via ISGylation. Our work has identified a distinct dsRNA induced stress response in the embryo reflecting an ancient innate immune memory before the establishment of the IFN system. It also raises the provocative question as to the original protective role of p53 during evolution. Overall design: To characterize the distribution of ribosomes on mRNA we performed Ribosome profiling Ribo seq analysis with RNA seq on dsRNA injected embryos.       Zebrafish Riboseq low dose dsRNA2 GSM8228800   source name:whole embryo|tissue:whole embryo|developmental stage:50% epiboly stage|cell type:embryonic cell|genotype:wild type|treatment:dsRNA|geo loc name:missing|collection date:missing Zebrafish Riboseq low dose dsRNA2 The library underwent quality control assessment and was subjected to Illumina Novaseq 6000 sequencing. Bio informatics analysis of RIBOseq profilling was performed to analyze the library data. Assembly: GRCz10 Supplementary files format and content: Excel file includes raw counts for each Sample Library strategy: Ribo seq whole embryo   Both control group and dsRNA injected embryos at xxx hpf were thoroughly lysed on ice using lysis buffer.The lysate was then centrifuged at 12000g at 4°C for 10 minutes to remove cellular components including undigested material such as cell nuclei.Then RNaseI was added to the supernatant and incubated at 25°C for 30 minutes to digest RNA while the RNA fragments protected by ribosomes were preserved. Subsequently an RNA inhibitor was added to terminate the digestion reaction. The lysate was subjected to sucrose density gradient centrifugation and fractions containing single peaks at 260nm wavelength around the 80S monosome region were collected. The collected mixture was then thoroughly lysed using Trizol for RNA extraction. RNA fragments within the size range of 26 34nt was separated using polyacrylamide gel electrophoresis without xxx and the corresponding bands were collected. The recovered bands were subjected to ligation reaction where a preadenylylated and 3’ blocked linker 5’ rApp CTGTAGGCACCATCAAT NH2 3’ was attached to the three prime end of the RNA. The ligated products were then recovered by performing polyacrylamide gel electrophoresis. Subsequently the recovered RNA fragments were reverse transcribed using a reverse primer to obtain extended cDNA molecules. The purified cDNA was subjected to circularization by using CircLigase Epicentre CL4111K resulting in the formation of circular cDNA molecules. To remove residual rRNA components in the cDNA a method involving hybridization with complementary primers specific to rRNA and subsequent heat denaturation was employed. The remaining circularized cDNA was then amplified through PCR and barcode sequences were incorporated.   tissue:whole embryo|developmental stage:50% epiboly stage|cell type:embryonic cell|genotype:wild type|treatment:dsRNA GSM8228800 GSM8228800: Zebrafish Riboseq low dose dsRNA2; Danio rerio; OTHER GSM8228800 r1 GSM8228800 1 Both control group and dsRNA injected embryos at xxx hpf were thoroughly lysed on ice using lysis buffer.The lysate was then centrifuged at 12000g at 4°C for 10 minutes to remove cellular components including undigested material such as cell nuclei.Then RNaseI was added to the supernatant and incubated at 25°C for 30 minutes to digest RNA while the RNA fragments protected by ribosomes were preserved.
