Characterization of Triptolide-Induced Hepatotoxicity by Imaging and Transcriptomics in a Novel Zebrafish Model.

Project description:Triptolide is a vine extract used in traditional Chinese medicines and associated with hepatotoxicity. In vitro data suggest that inhibition of RNA synthesis may be the mechanism of toxicity. For studying drug-induced liver injury the zebrafish has experimental, practical and financial advantages compared with rodents. The aim of this study was to explore the mechanism of triptolide toxicity using zebrafish as the model system. The effect of triptolide exposure on zebrafish larvae was determined with regard to mortality, histology, expression of liver specific microRNA-122 and liver volume. Fluorescent microscopy was used to track toxicity in the Tg(-2.8lfabp:GFP)as3 zebrafish line. Informed by microscopy, RNA-sequencing was used to explore the mechanism of toxicity. Triptolide exposure resulted in dose-dependent mortality, a reduction in the number of copies of microRNA-122 per larva, hepatocyte vacuolation, disarray and oncotic necrosis, and a reduction in liver volume. These findings were consistent across replicate experiments. Time-lapse imaging indicated the onset of injury was 6?h after the start of exposure, at which point, RNA-sequencing revealed that 88% of genes were down-regulated. Immune response associated genes were up-regulated in the triptolide-treated larvae including nitric oxide synthase. Inhibition of nitric oxide synthase increased mortality. Triptolide induces hepatotoxicity in zebrafish larvae. This represents a new model of drug-induced liver injury that complements rodents. RNA sequencing, guided by time-lapse microscopy, revealed early down-regulation of genes consistent with previous invitro studies, and facilitated the discovery of mechanistic inflammatory pathways.

Mercury-Induced Hepatotoxicity in Zebrafish

Project description:Full title: Mercury-Induced Hepatotoxicity in Zebrafish: In Vivo Mechanistic Insights from Transcriptome Analysis, Phenotype Anchoring and Targeted Gene Expression Validation In this study, we performed microarray-based expression profiling on liver of zebrafish exposed to 200 Âµg/L of mercuric chloride for 8-96 h, to identify global transcriptional programs and biological pathways involved in mercury-induced adaptive responses under in vivo environment. We analyzed 12 arrays for mercuric chloride treated zebrafish liver and 12 arrays for control liver.

Dysregulation of lncRNAs and circRNAs in mouse testes after exposure to triptolide

Project description:Triptolide has been shown to exert various pharmacological effects on systemic autoimmune diseases and cancers. However, its severe toxicity, especially reproduction toxicity, prevents wide clinical use for those people with fertility needs. Noncoding RNAs including lncRNAs and cicrRNAs are regulatory molecules that mediate a wide variety of physiological activities, which are critical for spermatogenesis, and their dysregulation might lead to male infertility. However, whether they are involved in triptolide-induced reproduction toxicity is fully unknown. Here, after exposure of mice to triptolide for 35 day, the total RNAs were used to investigate lncRNAs/cicrRNAs/mRNAs expression profiles by strand-specific RNA sequencing at the transcriptome level to help determine any RNA-related mechanisms in triptolide-induced toxicity. The results showed that triptolide significantly decreased the testicular weight, damaged testis and sperm morphology, reduced sperm motility and density. Furthermore, there's a remarkable deformity in sperm head and tail in triptolide-exposed mice. At the transcriptome level, the triptolide-treated mice exhibited aberrant expression profiles for lncRNAs/cicrRNAs/mRNAs, many of them were dysregulated. Gene ontology and pathway analyses revealed that the functions of differentially expressed lncRNA targets, cicrRNAs cognate genes and mRNAs were closely linked with many processes involved in spermatogenesis. Additionally, many newly identified lncRNAs /cicrRNAs displayed inducible expression, suggesting that they might be good candidate markers for triptolide-induced male reproductive toxicity. This study gives us an insight into understanding the reproductive system toxicity of triptolide and reminds us to strengthen the research on increasing efficacy and decreasing toxicity of triptolide.
