Exposure to environmental contaminants such as 2 3 7 8 tetrachlorodibenzo p dioxin TCDD is believed to be a cause of idiopathic male infertility. To understand TCDD induced disruption of spermatogenesis at the single cell level we profiled adult zebrafish testes with and without xxx life exposure to TCDD. Secondly to investigate the potential for technical artifacts in scRNA seq we compared bulk sequenced and scRNA seq paired samples from control and TCDD exposed samples and included an intact control fish to account for dissociation induced artifacts. We found scRNA seq and bulk seq of dissociated testes produced markedly different profiles both toxicologically and transcriptomically. Through scRNA seq we found TCDD exposure induces mid late germ cell apoptosis while increasing the population of spermatogonial stem cells. Bulk seq on the same cells returned results of immune dysregulation. The transcriptome was unequally detected by scRNA seq and bulk seq with scRNA seq biased towards detecting longer and more abundant transcripts but this was not mediated by TCDD exposure. Overall design: Zebrafish were exposed to 50 pg/mL TCDD or vehicle solution for 1 hour during sexual differentiation and maturation. Adult testes were dissected for toxicotranscriptomic analysis. Samples were prepared by dissociation for scRNA seq remained intact for bulk seq or were dissociated for bulk seq. | pubmed:35615540;pubmed:35799832 | bulk seq control testes rep 2 to be compared to scRNA seq control testes | GSM5820558 | tissue:testes|strain:AB|treatment:50 pg/mL 0.1% DMSO|sample preparation:dissociated cell suspension | bulk seq control testes rep 2 to be compared to scRNA seq control testes | Reads were aligned and tabulated by individual cells in each sample using Cell Ranger 6.01 Count data was imported to Seurat version 4.0.4 for quality control QC filtering clustering dimensionality reduction visualization and differential gene expression Each sample was filtered to cells containing at least 500 features with clusters requiring a minimum of 30 cells. Samples were merged prior to normalization and clustering resolution 0.3.

Cell viability was assessed at 90% or better in each replicate. cDNA libraries of mRNA from 25 000 cells were constructed using the 10x Genomics platform and sequenced on a NovaSeq. | Zebrafish were maintained on a 14:10h light/dark cycle with temperatures maintained at 27°C– 30°C. Fish were fed twice daily. Fish were raised in beakers with daily water changes. Animal use protocols were approved by the Institutional Animal Care and Use Committees at Wayne State University and the University of Wisconsin Madison according to the National Institutes of Health Guide to the Care and Use of Laboratory Animals Protocol No. M00489. | strain:AB|treatment:50 pg/mL 0.1% DMSO|sample preparation:dissociated cell suspension | GSM5820558 | GSM5820558: bulk seq control testes rep 2 to be compared to scRNA seq control testes; Danio rerio; RNA Seq | GSM5820558 r1 | GSM5820558 | 1 | Fish were euthanized in tricaine methanesulfonate; testes were removed and enzymatically dissociated. 5 000 cell suspensions were obtained for each replicate.
