Therefore we injected 700nm polystyrene into the yolk at 2 dpf and took samples at xxx and 3 days post injection. Overall design: This deep sequence study was designed to determine the gene expression profile by polystyrene particle toxicity. RNA was isolated from embryos at 1 and 3 days post injection. Wildtypes zebrafish embryos were micro injected into the yolk 2dpf with 1nl of 5mg/ml of 700nm red fluorescent polystyrene particles suspended in PVP Polyvinylpyrrolidone n=3 mock injected with pvp n=2 or Non injected as a control n=3. post injections embryos were transferred into fresh egg water and incubated at 28°C. At 1 and 3 days post injection 10 embryos per group were snap frozen in liquid nitrogen and total RNA was isolated using TRIZOL reagent.		pubmed:28704660		Nano 3dpi C	GSM2058661		source name:Danio rerio embryo 5 dpf type:Wildtype; injected with 1nl of 5mg/ml of 700nm red fluorescent polystyrene particles into the yolk at 2 dpf; RNA isolated at 5 dpf = 3dpi timepoint. Biological replica 3\|tissue:embryo	Nano 3dpi C	GeneTiles was used for quantification and visualization of the RNAseq data Bowtie2 is used to align the reads in the fastq file to the genome obtained from Ensemble. Bowtie2 generates SAM files that contain the reads together with the location on the genome. Samtools is used to convert and compress the SAM files into a binary BAM file. Samtools is furthermore used to sort the reads in the BAM files based on the aligned read location in the genome resulting in a sorted BAM file. The BAM files is indexed to be able to quickly find the aligned reads based on a location in the genome i.e. to be able to quickly search the BAM file. The index is a saved as a BAI file. Using the available annotation from Ensemble we can search the BAM file for reads within a gene using exon starting positions and lengths. This is done with a python script. The output of this script is a tab separated file tsv containing the read counts per gene. We used DESeq an R script to perform statistical analysis. The DESeq script is used to normalise the reads per gene based on divided by the total number of reads obtained per sample. Then variance and average of the measurement compared to the control can be expressed as a P value by calculating the dispersion per gene using DESeq. The size factors as well as the P values are stored in ‘tsv’ files. Using a script all tsv files are combined into xlsx files e.g. per experiment chromosome per filtered results of most significant reads or highest ratio between measurement and control.

At 1 and 3 days post injection 3 dpf and 5 dpf 10 embryos per treatment group were snap frozen in liquid nitrogen and total RNA was isolated using TRIZOL reagent.	Embryos for RNA isolation were snap frozen in liquid nitrogen and subsequently stored at 80°C. Embryos were homogenized in 1 ml of TRIZOL® Reagent Invitrogen and subsequently total RNA was extracted according to the manufacturer’s instructions. The RNA samples were incubated for 20 min at 37° with 10 units of DNaseI Roche Applied Science to remove residual genomic DNA prior to purification using the RNeasy MinElute Cleanup kit Qiagen according to the RNA clean up protocol. The integrity of the RNA was confirmed by Lab on chip analysis using the 2100 Bioanalyzer Agilent Technologies. RNA libraries were prepared for sequencing using standard Illumina protocols	Zebrafish were handled in compliance with the local animal welfare regulations and maintained according to standard protocols http://ZFIN.org.
