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.

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.

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 T\u00fcbingen 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", null, "1cell ncRNA seq", "GSM5069281", null, "tissue:embryo|strain:Tubingen|developmental stage:1cell stage|treatement:no", "1cell 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.
