| Sample type |
SRA |
| |
|
| Source name |
Embryo
|
| Organism |
Danio rerio |
| Characteristics |
tissue: Embryo
genotype: WT (TLAB)
treatment: untreated
time: 4 hpf
|
| Treatment protocol |
Embryos were collected as soon as they were laid and put into E3 medium (5 mM NaCl, 0.17 mM KCl, 0.33 mM CaCl2, 0.33 mM MgSO4, 10−5% methylene blue) containing inhibitors. Embryos were kept in this medium for the duration of the experiment. For this experiment we used already established concentrations for inhibitors: oligomycin (Millipore, 495455) 1µM, actinomycin D (Sigma-Aldrich, A1410) 10µg/ml. Untreated embryos were kept alongside as controls.

| Growth protocol |
E3 medium (5 mM NaCl, 0.17 mM KCl, 0.33 mM CaCl2, 0.33 mM MgSO4, 10−5% methylene blue).
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was extracted using RNeasy Mini Kit (Qiagen, 175023525). 1.5µg of total RNA was used for the construction of sequencing libraries.
Samples were submitted to VBCF NGS facility for library preparation and NGS sequencing. Samples were prepared with Quantseq kit (Lexogen) protocol.

| Data processing |
Reads were preprocessed using umi2index (Lexogen) to add the UMI sequence to the read identifier, and trimmed using BBDuk v38.06 (ref=polyA.fa.gz,truseq.fa.gz k=13 ktrim=r useshortkmers=t mink=5 qtrim=r trimq=10 minlength=20). Reads mapping to abundant sequences (mitochondrial chromosome, phiX174 genome, and silva zebrafish rRNAs from the SILVA rRNA database) were removed using bowtie2 v2.3.4.1 alignment.
Remaining reads were analyzed using genome and gene annotation for the GRCz11 assembly obtained from Danio rerio Ensembl release 104. Reads were aligned to the genome using star v2.6.0c, alignments were processed using collapse_UMI_bam (Lexogen) and reads in genes were counted with featureCounts (subread v1.6.2) using strand-specific read counting (-s 1) .
Assembly: GRCz11
