Studies of these pollutants' toxic effects on development have not fully elucidated the potential underlying mechanisms. Therefore  in this study  we aim at investigate the developmental toxicity induced by cigarette smoke extract CSE at concentrations of 0.25%  1%  and 2.5% using a zebrafish embryo toxicity test and integrated transcriptomic analysis of microRNA miRNA and messenger RNA mRNA. The findings revealed that CSE caused developmental toxicity  including increased mortality and decreased incubation rate  in a dose dependent manner. Moreover  CSE induced malformations and apoptosis  specifically in the head and heart of zebrafish larvae. We used mRNA and miRNA sequencing analyses to compare changes in the expression of genes and miRNAs in zebrafish larvae. The bioinformatics analysis indicates that the mechanism underlying CSE induced developmental toxicity was associated with genetic repair impairment  apoptosis disorder  and lipid metabolism disturbance. The enrichment analysis and RT qPCR show that the ctsba gene plays a crucial function in embryo developmental apoptosis  and the fads2 gene mainly regulates lipid metabolic toxicity. The results of this study improve the understanding of CSE induced developmental toxicity in zebrafish embryos and contribute insights into the formulation of novel preventive strategies against tobacco pollutants during early embryonic development.", null, null, null, null, "S21K1226", null, "library ID:M 2|title:Medium 2|library strategy:OTHER|library source:METATRANSCRIPTIOMIC|library selection:other|library layout:paired|platform:ILLUMINA|instrument model:RNA seq|filetype:fastq|filename:S21K1226 rep1 1 URNA S70 L003 R1 001.fastq|filename2:S21K1226 rep1 1 URNA S70 L003 R2 001.fastq|host:missing|isolation source:missing|collection date:missing|geographic location:missing|latitude and longitude:missing|age:missing|breed:missing|cultivar:missing|dev stage:missing|ecotype:missing|isolate:missing|sex:missing|strain:missing|tissue:missing|BioSampleModel:Model organism or animal", null, null, null, null, null, null, null, null, "Medium 2", "M 2", "M 2", "missing", null, null, "RNA-Seq", "METATRANSCRIPTOMIC", "other", "PAIRED", "ILLUMINA", "Illumina NovaSeq 6000", null, "SRP491086", null, null, "S21K1226_rep1_1_URNA_S70_L003_R1_001.fastq.gz S21K1226_rep1_1_URNA_S70_L003_R2_001.fastq.gz", "fastq fastq", 6310969500.0, 21036565.0, "S21K1226 rep1 1 URNA S70 L003 R1 001.fastq.gz", "0:150 1:150", "A:1688391347;C:1451351943;G:1503321023;T:1667755412;N:149775", 150, 150, null, null, 1688391347, 1451351943, 1503321023, 1667755412, 149775, "SRX23704458", "SRS20534453", "SRA1806456", "The Second Affiliated Hospital of Shantou University Medical College|Department of Burns and Plastic Surgery", "The Second Affiliated Hospital of Shantou University Medical College", null, null, null, null, null, null, null, null, null, null, null, "B", "B", "biological fallback assumption", "illumina", "novaseq_era", "unknown", "small_rna", "unknown", "bulk", "unknown", "unknown", null, "China", "2024-02-22", "Undetermined", "Multi-stage", "Undetermined", "Undetermined"]], "columns": ["rowid", "run.accession", "experiment.accession", "sample.accession", "study.accession", "bioproject", "study.title", "study.alias", "study.type", "study.abstract", "study.attributes", "study.PMIDs", "sample.description", "sample.title", "sample.alias", "sample.centername", "sample.attributes", "GEOsample.title", "GEOsample.dataprocessing", "GEOsample.source", "GEOsample.treatmentprotocol", "GEOsample.extractprotocol", "GEOsample.growthprotocol", "GEOsample.characteristics", "GEOsample.accession", "experiment.title", "experiment.alias", "experiment.library_name", "experiment.design_description", "experiment.library_construction_protocol", "experiment.attributes", "experiment.library_strategy", "experiment.library_source", "experiment.library_selection", "experiment.library_layout", "experiment.platform", "experiment.instrument_model", "experiment.spot_descriptor", "experiment.study_ref", "run.title", "run.attributes", "run.filename", "run.semantic_name", "run.total_bases", "run.total_spots", "run.alias", "run.read_lengths", "run.base_counts", "run.r1_length", "run.r2_length", "run.r3_length", "run.r4_length", "run.Acount", "run.Ccount", "run.Gcount", "run.Tcount", "run.Ncount", "run.experiment", "run.pool_member", "submission.accession", "submission.srasource", "submission.bioprojectsource", "seqdetective.n_mates", "seqdetective.mapping_rate.mate1", "seqdetective.mapping_rate.mate2", "seqdetective.nofeature_rate.mate1", "seqdetective.nofeature_rate.mate2", "seqdetective.sparsity.mate1", "seqdetective.sparsity.mate2", "seqdetective.pos_strand_rate.mate1", "seqdetective.pos_strand_rate.mate2", "seqdetective.readlen.mate1", "seqdetective.readlen.mate2", "seqdetective.judgement.mate1", "seqdetective.judgement.mate2", "seqdetective.judgement.reason", "platform_family", "instrument_generation", "read_bias", "selection_class", "prep_kit", "sc_or_bulk", "tech_class", "technology", "tech_variant", "submission.bioprojectsource.country", "earliest_date", "devstage_curation", "devstage_curation_coarse", "tissue_curation", "tissue_curation_coarse"], "primary_keys": ["rowid"], "primary_key_values": ["30652"], "units": {}, "query_ms": 8.653641998535022}
