49332 49332 SRR7888761 SRX4726390 SRS3810123 SRP162319 PRJNA492406 Profiles analysis reveals circRNAs involving zebrafish physiological development GSE120289 Transcriptome Analysis Recent studies have found that known functions of circRNAs include sequestration of microRNAs or proteins modulation of transcription and interference with splicing and even translation to produce poly peptides. The zebrafish model is also demonstrably similar to humans in many studies. In order to explore the changes in circRNAs during embryonic development further to research the mechanism of action of circRNAs in development related diseases. Zebrafish embryos at blastula period gastrula period segmentation period throat stage and incubation period were collected. Illumina deep sequencing technology and CIRI algorithm were used to detecting circRNAs. Totally we identified 1028 circRNAs junction reads = 5 and p < 0.05. Considering that circRNAs function is related to host genes then bioinformatics analysis revealed these differentially expressed host genes are involved in NOTCH signaling pathways cardiovascular system development retinal ganglion cell axon guidance and so on. Moreover circRNAs can participate in biological regulation through miRNA sponges function. TargetScan and miRanda were used to predict 73 miRNAs binding to circRNAs such as miR 19b miR 124 and so on some miRNAs play important roles in embryogenesis. The peak expression of circRNAs is distributed at different time points suggesting that it may be involved in embryogenesis at different stages. Our study provides a foundation for understanding the dynamic regulation of circRNA transcriptomes during embryogenesis and identifies novel key circRNAs that might control embryonic development in zebrafish model. Overall design: circRNAs of five periods blastula gastrula segmentation throat and incubation in zebrafish were detected by deep sequencing using Illumina HiSeq 2500.       72h GSM3397729   source name:Embryo|tissue:Embryo|age:72 hpf|developmental stage:incubation|strain:Tubingenz|genotype:WT 72h Illumina Casava1.7 software used for basecalling. Sequenced reads were trimmed for adaptor sequence and masked for low complexity or low quality sequence then mapped to z10 whole genome using bwa 0.7.5a r405 with parameters "mem T 19". CircRNA prediction of sequencing results by CIRI algorithm v1.1. SRPBM Spliced Reads per Billion Mapped Reads=number of circular reads/number of mapped reads units in billion/read length used to normalize the expression of circRNAs. For differential expression analysis of circRNAs raw counts of reads that spanned a particular head to tail junction were analyzed using edgeR package version 3.12.1 with TMM normalization in generalized linear model. The Trimmed Mean of M values TMM normalization method was used to remove the size basis of sequencing libraries between samples. The following criteria were used to screen out significantly differentially expressed circRNAs: Fold change FC ≥2 and p< 0.05. Genome build: z10 Supplementary files format and content: tab delimited text files include SRPBM values and junction reads for each Sample. Embryo Zebrafish were reared at 28±1℃ in a water circulatory system that osmotic pressure stability UV disinfects and aerates the recycled water.The embryos were obtained post spontaneous mating from sexually mature wild type WT adult fish and cultivated at 28.5±0.5℃. Morphological features were used to judge the stage of embryonic development. Total RNA was isolated using the standard TRIzol Invitrogen protocol Genomic DNA was removed by DNase treatment. Then the total RNA were subject to ribosomal RNA depletion according to the manufacturer’s protocol of RiboMinus kit Life Technology. The quality of the RNA and lack of contaminating ribosomal RNA were confirmed using the Agilent 2100 Bio analyzer.

However it is unknown whether five primetRFls could feed back to regulate tRNA biogenesis. Here we show that five primetRFlGly/GCC and five primetRFlGlu/CTC function to promote transcription of corresponding tRNA genes and are essential for vertebrate early embryogenesis. During zebrafish embryogenesis dynamics of five primetRFlGly/GCC and five primetRFlGlu/CTC levels correlates with that of tRNAGly/GCC and tRNAGlu/CTC levels. Morpholino mediated knockdown of five primetRFlGly/GCC or five primetRFlGlu/CTC down regulates tRNAGly/GCC or tRNAGlu/CTC levels respectively and causes embryonic lethality that is efficiently rescued by co injection of properly refolded corresponding tRNA. In zebrafish embryos tRNA:DNA and five primetRFl:DNA hybrids commonly exist on the template strand of tRNA genes. Mechanistically unstable five primetRFl:DNA hybrid may prevent the formation of transcriptionally inhibitory stable tRNA:DNA hybrids on the same tRNA loci so as to facilitate tRNA genes transcription. The uncovered mechanism may be implicated in other physiological and pathological processes. Overall design: For small RNA sequencing total RNA were extracted respectively from wildtype zebrafish embryos Tübingen Strain of 6 chosen stages and then subjected to small RNA library preparation individually. To investigate the distribution and stability of R loop on genome we performed ssDRIP seq with S9.6 antibody which specifically recognize RNA:DNA hybrid. Two replicates from wildtype embryos of 256c sphere and shield stage were collected to perform ssDRIPseq. RNaseH pre treated genome DNA was used as negative control which was also performed the standard ssDRIP seq procedure. Genomic DNA extracted from these samples were fragmentated by restriction enzymes and then immunoprecipitated by S9.6 antibody.The ssDNA strands in RNA:DNA hybrids were purified and subjected to library preparation. parent bioproject:PRJNA753013 pubmed:34797706   24hpf ncRNA seq GSM5069285   tissue:embryo|strain:Tubingen|developmental stage:24 hpf stage|treatement:no 24hpf ncRNA seq For data processing reads were quality checked by FastQCVersion 0.11.8 and adaptors were cut off by Cutadapt Version 1.16 and only reads that lay between 18 40 nt were kept.

The aim of this step is removing the 2 3’ cyclic phosphate group from the 3’end of 5’tRFls and add phosphate group to the 5’end of 3’tRFs.

However it is unknown whether five primetRFls could feed back to regulate tRNA biogenesis. Here we show that five primetRFlGly/GCC and five primetRFlGlu/CTC function to promote transcription of corresponding tRNA genes and are essential for vertebrate early embryogenesis. During zebrafish embryogenesis dynamics of five primetRFlGly/GCC and five primetRFlGlu/CTC levels correlates with that of tRNAGly/GCC and tRNAGlu/CTC levels. Morpholino mediated knockdown of five primetRFlGly/GCC or five primetRFlGlu/CTC down regulates tRNAGly/GCC or tRNAGlu/CTC levels respectively and causes embryonic lethality that is efficiently rescued by co injection of properly refolded corresponding tRNA.

The lysate was centrifuged at 12 000 rpm for 10 min and the supernatant was collected and mixed with 200 μl chloroform in a fresh tube. post centrifugation at 12 000 rpm for 10 min at 4℃ the supernatant was transferred to a fresh tube with addition of equal volume of isopropanol and incubated at room temperature for 15 min followed by thorough mix and centrifugation at 12 000 rpm for 10 20 min. The RNA pellet was washed by 75% ethanol once and was stored as pellet in 75% ethanol at 80℃ until all samples were collected. Two pretreatment steps were included: First purified total RNAs were treated with T4 Polynucleotide Kinase NEB M0201S with ATP for 30 min at 37℃ then purified by phenol: chloroform extraction. The aim of this step is removing the 2 three prime cyclic phosphate group from the three primeend of five primetRFls and add phosphate group to the five primeend of three primetRFs. In the second step total RNAs were treated with ALKB protein mix as mentioned above. Purified total RNAs were then subjected to small RNA library preparation. For small RNA sequencing: Small RNA libraries using 1 μg RNA each were prepared using the NEBNext Multiplex Small RNA Library Prep Set for Illumina NEB according to the manual. The amplified DNA from each sample was first concentrated by DNA concentrator spin column Zymo Research then bands of 135 160 bp about the length of 15 40 nt RNA ligated with both adaptors were manually selected on native PAGE gel. DNAs were eluted from the gel piece with 0.3 M NaOAc pH 4.5 followed by precipitation by adding 2.5 volumes of ethanol.
