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.", null, null, null, "72h", "GSM3397729", null, "source name:Embryo|tissue:Embryo|age:72 hpf|developmental stage:incubation|strain:Tubingenz|genotype:WT", "72h", "Illumina Casava1.7 software used for basecalling.

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.
