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.

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.

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.

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.

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.

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.

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.

RNA isolated from the oocyte or embryo lysate was mixed with 8 pmol KXSH009  8 pmol KXSH010  and 2x SSC 0.3 M NaCl  30 mM sodium citrate pH 7.0 in a total of 50 µl. The RNA and oligos were annealed by incubation at 70°C for 5 min and then slowly cooling to 23°C at 0.1°C/sec. The annealed mixture was combined with 40 µl MyOne Streptavidin C1 beads Thermo Fisher  65002 and incubated for 20 min at 23°C on a thermal mixer  shaking with 15 sec on and 1 min 45 sec off. The supernatant was separated from the beads with a magnetic rack and removed. The beads were washed twice with 300 µl 1xB&W buffer 5 mM Tris HCl pH 7.5  0.5 mM EDTA  1 M NaCl and once with 300 µl 2x SSC. The RNA was eluted from the beads first with 100 µl 10 mM HEPES pH 7.5 at 65°C for 3 min and then second with 100 µl water at 65°C for 3 min. The eluates were combined  precipitated with ethanol  and resuspended in 6.5 µl water. The anti sense oligo enriched RNA or the RNA isolated from oocyte or embryo lysates was ligated to a pre adenylated 3ʹ adapter in a 10 µl reaction containing 5 µM 3ʹ adapter KXS330  50 mM HEPES pH 7.5  10 mM MgCl2  10 mM dithiothreitol  1 unit/µl T4 RNA ligase 1 New England Biolabs  M0204S. The ligation reaction was incubated at 23°C for 150 min. post ligation  RNA was extracted with phenol/chloroform  precipitated with ethanol  and resuspended in 11.4 µl water. The ligated RNA was mixed with 0.6 µl 100 µM reverse transcription primer KXS037 in a total volume of 12 µl  incubated at 65°C for 5 min  and cooled on ice for 1 min. The annealed RNA was reverse transcribed in a 20 µl reaction containing 1x First Strand Buffer  500 µM dNTPs  5 mM dithiothreitol  1 unit/µl SUPERase•In  and 200 units SuperScript III Thermo Fisher  18080044 at 50°C for 1 hr. post reverse transcription  RNA was hydrolyzed with 3.3 µl 1 M NaOH at 90°C for 10 min  followed by neutralization with 36.7 µl 1 M HEPES pH 7.5 and the cDNA was collected by desalting with a Micro Bio Spin P 30 column. 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. The PCR amplified library was cleaned up twice with AMPure XP beads Beckman Coulter  A63881 with a beads to sample ratio of 1.2. For sequencing of endogenous mRNA polyA tail length  libraries were prepared with PAL seq v3 for frog oocytes or PAL seq v4 for frog embryos  fish embryos  and mouse oocytes as described previously PMID: 34213414. 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. The seven cDNA libraries made from mRNAs of zebrafish embryos at different stages were mixed at roughly equal molar ratios in a total of 5 fmol. Fifty pmol KXSH015 and 2x SSC were added in a total of 100 µl. The cDNAs and the oligo were annealed by incubation at 65°C for 5 min and then slowly cooling to 23°C at 0.1°C/sec. The annealed mixture was combined with 100 µl MyOne Streptavidin C1 beads and incubated for 20 min at 23°C on a thermal mixer  shaking with 15 sec on and 1 min 45 sec off. The supernatant was separated from the beads with a magnetic rack. The beads were washed once with 200 µl 1xB&W buffer. The supernatant and the wash were combined  precipitated with ethanol  and resuspended in 30 µl water. The oligo depleted libraries were sequenced again as a technical replicate. Sequencing data of replicates were merged for each sample post monitoring consistency.,,OTHER,TRANSCRIPTOMIC,other,PAIRED,ILLUMINA,Illumina HiSeq 2500,,SRP455680,,,Fish_embryo_mRNA_1cell_PAL_seq_v4_rep2_raw_read1.fastq.gz Fish_embryo_mRNA_1cell_PAL_seq_v4_rep2_raw_read2.fastq.gz,fastq fastq,3406093776.0,11094768.0,GSM7716865 r2,0:52 1:255,A:868054279;C:890446070;G:945289336;T:695324057;N:6980034,52,255,,,868054279,890446070,945289336,695324057,6980034,SRX21396036,SRS18636194,SRA1694849,Whitehead Institute,Whitehead Institute,2,0.00049,0.0,0.00014,0.0,0.99939,1.0,0.58974,,52,255,T,T,mates < 9% mapping rate,illumina,hiseq_era,unknown,poly_a,unknown,bulk,bulk,bulk,,United States,2023-08-17,Zygote,Embryo,Embryo Imprecise,All anatomical structures

A large group of animals follow a preformation strategy to generate their primordial germ cells PGCs.

This study identifies Rbm24a as an enssential localized germ plasm protein component that controls the formation of large and functional germ plasm granules.
