However  how tail lengths are controlled at different developmental stages has been unclear. Here  we performed tail length and translational profiling of mRNA reporter libraries each with > 10 million three prime UTR sequence variants in frog oocytes and embryos  and fish embryos. These analyses revealed that the UUUUA motif specifies cytoplasmic polyadenylation and identified diverse context features that modulate the activity of this 5 mer. Additional sequence motifs drive stage specific deadenylation in embryos  and UUUUA and C rich motifs drive tail length independent translational repression in oocytes. A neural network model accurately predicts tail length change during oocyte maturation in frogs  mice  and humans. Analyses of human sequence variants showed that those predicted to disrupt tail length control have been under negative selection  implying that our insights into control of polyA tail length and translation have implications for human health and fertility. Overall design: Sythetic mRNA reporter libraries with random three prime UTR sequences under four different sequence contexts were injected into frog oocytes and embryos and fish embryos. PolyA tail lengths were measured to at different developmental stages to examine sequence motifs that caused tail length changes. At the same time  polyA tail lengths of endogenous mRNAs from frog oocytes and embryos  fish embryos  and mouse oocytes were measured to investiage how their tail lengths were controlled.

The cDNA library was amplified in a 50 µl PCR reaction with KXS037 and a barcoded primer Supplemental using the KAPA HiFi HotStart Kits following the manufacturer's suggested protocol for 10–15 cycles.

When preparing the sequencing libraries of mRNAs from fish embryos  a different 3ʹ adapter KXS013 was used for 3ʹ end ligation  and polyA selected mRNA from HeLa cells was used as spike in  replacing polyA selected mRNA from zebrafish ZF4 cell line. The first round of sequencing results suggested that a large fraction of the fish mRNA libraries was 5.8S rRNA. The cDNA of 5.8S rRNA was depleted from the cDNA libraries with an antisense oligo.

However  how tail lengths are controlled at different developmental stages has been unclear. Here  we performed tail length and translational profiling of mRNA reporter libraries each with > 10 million three prime UTR sequence variants in frog oocytes and embryos  and fish embryos. These analyses revealed that the UUUUA motif specifies cytoplasmic polyadenylation and identified diverse context features that modulate the activity of this 5 mer. Additional sequence motifs drive stage specific deadenylation in embryos  and UUUUA and C rich motifs drive tail length independent translational repression in oocytes. A neural network model accurately predicts tail length change during oocyte maturation in frogs  mice  and humans. Analyses of human sequence variants showed that those predicted to disrupt tail length control have been under negative selection  implying that our insights into control of polyA tail length and translation have implications for human health and fertility. Overall design: Sythetic mRNA reporter libraries with random three prime UTR sequences under four different sequence contexts were injected into frog oocytes and embryos and fish embryos. PolyA tail lengths were measured to at different developmental stages to examine sequence motifs that caused tail length changes. At the same time  polyA tail lengths of endogenous mRNAs from frog oocytes and embryos  fish embryos  and mouse oocytes were measured to investiage how their tail lengths were controlled.

The cDNA library was amplified in a 50 µl PCR reaction with KXS037 and a barcoded primer Supplemental using the KAPA HiFi HotStart Kits following the manufacturer’s suggested protocol for 10–15 cycles.

However  how the maternally supplied transcripts are dynamically regulated during MZT remains largely unknown. Herein  through genome wide profiling of RNA 5 methylcytosine m5C in zebrafish early embryos  we show that m5C methylated maternal mRNAs display higher stability during MZT. We identify that the Y box binding protein 1 Ybx1 prefers to recognizing m5C modified mRNAs through p p interaction with a key residue Trp45 in its cold shock domain CSD  which plays essential roles in maternal mRNA stability and early embryogenesis of zebrafish. Cooperated with an mRNA stabilizer Pabpc1a  Ybx1 promotes the stability of its target mRNAs in an m5C dependent manner. Our study demonstrates a novel mechanism of RNA m5C methylation regulated maternal mRNA stability during zebrafish MZT  highlighting the critical role of m5C mRNA methylation in early development.

However  the mechanisms that activate the silent genome post fertilization are poorly understood. Here  we show that transcriptional competency in zebrafish is regulated by Brd4 and p300 dependent histone acetylation. Live imaging of transcription revealed that genome activation begins at the miR 430 locus  is gradual and stochastic. We show that genome activation does not require slow down of the cell cycle and is regulated through translation of maternally inherited mRNAs. Among these  the enhancer regulators p300 and Brd4 can prematurely activate transcription and restore transcriptional competency when maternal mRNA translation is blocked  whereas inhibiting histone acetylation blocks genome activation. We conclude that p300 and Brd4 are sufficient to trigger genome wide transcriptional competency by regulating histone acetylation on the first zygotic genes in zebrafish. This mechanism is critical to initiating zygotic development and developmental reprogramming.,,,,RPF   WT 0h Cycloheximide Ribo  RPF,RPF   WT 0h CHX R  RPF AGN000073,,strain:TU/AB|age:0.0|dev stage:1cell|sex:pooled male and female|tissue:embryo|treatment:cyclohex|molecule:RNA|selection:r |condition:RPF|sample ref:AGS000069|replicate ref:AGN000073|replicate order:1|BioSampleModel:Model organism or animal,,,,,,,,,RPF   WT 0h Cycloheximide Ribo  RPF,AGR000135,AGR000135,RNA,,,OTHER,TRANSCRIPTOMIC,unspecified,SINGLE,ILLUMINA,Illumina HiSeq 2000,,SRP184786,,,AGR000135_R1.fastq.gz,fastq,2161849320.0,30025685.0,AGR000135 R1.fastq.gz,0:72,A:645981607;C:467229372;G:514731353;T:527710797;N:6196191,72,,,,645981607,467229372,514731353,527710797,6196191,SRX5354343,SRS4345561,SRA847217,Yale_Giraldez|Genetics,Yale_Giraldez_Group,1,0.0,,0.0,,1.0,,,,72,,T,,under 1.2% mapping rate,illumina,hiseq_era,unknown,unknown,unknown,bulk,unknown,unknown,,United States,2019-02-08,Zygote,Embryo,Embryo Imprecise,All anatomical structures

Supplementary files format and content: MS Excel file contains five prime and three prime read count and calculated RiboMeth seq score at all positions in the rRNA sequence.,unfertilized egg,,Tissues were homogenized and whole cell RNA was extracted using Qiazol Qiagen according to the manufacturer. RiboMeth seq: 5 10 ug of RNA was partially degraded by alkaline at denaturing temperatures. The size fraction 20 40 nt was purified on gels and linkers added using a system relying on a modified Arabidopsis tRNA ligase joining 2' three prime cyclic phosphate and five prime phosphate ends. The library fragments were then sequenced on the Ion Proton platform. See Birkedal U  Christensen Dalsgaard M  Krogh N  Sabarinathan R  Gorodkin J  Nielsen H.
