The validation case study of read-across based on IATA for hepatotoxicity of Naphthalene and its structurally similar analogs

Project description:Comparing biological similarity with in vitro test is expected to improve the reliability of read-across for systemic toxicity without animal test. However, because of few case studies, it was hindered to use of this concept for regulatory context. Thus, we compared biological similarity with in vitro test for structurally similar chemicals to demonstrate its validity for grouping chemicals and extract key considerations in read-across. In this study, we selected the hepatotoxicity of Naphthalene and its structurally similar analogs which have 90-day repeated dose toxicity data including 2,7-Naphthalenediol, 1,5-Naphthalenediol, and 1-Naphthol. To elucidate the potential mechanisms and compared them, we conducted in vitro microarray analysis with rat primary hepatocytes

Comparison of toxicological effects and exposure levels between triclosan and its structurally similar chemicals using in vitro tests for read-across case study

Project description:To improve prediction accuracy of read-across, we compared biological similarities between triclosan and its structurally similar chemicals including diclosan and 1-chloro-3-(4-chlorophenoxy) benzene. To elucidate and compare the potential mechanisms between them, we performed in vitro toxicogenomics with rat primary hepatocytes.

NaphS2 Gene Expression During Anaerobic Degradation of Naphthalene

Project description:Degradation of polycyclic aromatic hydrocarbons (PAHs) such as naphthalene by anaerobic microorganisms is poorly understood. Strain NaphS2, an anaerobic sulfate reducing marine delta-proteobacterium is capable of using naphthalene and the aromatic compound benzoate, as well as pyruvate, as an electron donors in the presence of sulfate. In order to identify genes involved in the naphthalene degradation pathway, we compared gene expression in NaphS2 during growth on benzoate vs. pyruvate, naphthalene vs. pyruvate, and naphthalene vs benzoate. For each experimental set, aRNA from NaphS2 was labelled Cy5 (experiment) or Cy3(control) with three biological replicates hybridized in duplicate. In addition, because of the size of the predicted genome of NaphS2, ORFs were divided into two separate array designs, designated set1 and set2, such that set1 and set2 represent two separate array designs (probe sets) to be treated separately in statistical analysis.

Project description:Ligand structure can affect the activation of nuclear receptors, such as estrogen receptors (ERs), and their control of signaling pathways for cellular responses including death and differentiation. We hypothesized that distinct biological functions of similar estradiol (E(2)) analogs could be identified by integrating gene expression patterns obtained from human tumor cell lines with receptor binding and functional data for the purpose of developing compounds for treatment of a variety of diseases. We compared the estrogen receptor subtype selectivity and impact on signaling pathways for three distinct, but structurally similar, analogs of E(2). Modifications in the core structure of E(2) led to pronounced changes in subtype selectivity for estrogen receptors, ER-α or ER-β, along with varying degrees of ER dimerization and activation. While all three E(2) analogs are predominantly ER-β agonists, the cell growth inhibitory activity commonly associated with this class of compounds was detected for only two of the analogs and might be explained by a ligand-specific pattern of gene transcription. Microarray studies using three different human tumor cell lines demonstrated that the analogs distinctly affect the transcription of genes in signaling pathways for chromosome replication, cell death, and oligodendrocyte progenitor cell differentiation. That the E(2) analogs could lower tumor cell viability and stimulate neuronal differentiation confirmed that gene expression data could accurately distinguish biological activity of the E(2) analogs. The findings reported here confirm that cellular responses can be regulated by making key structural alterations to the core structure of endogenous ER ligands.

Whole transcriptome analysis of Acinetobacter calcoaceticus Aca13 induced by n-hexadecane or naphthalene

Project description:Petroleum hydrocarbons are recalcitrant contaminants, which has caused most serious environmental problems. Acinetobacter calcoaceticus Aca13 was isolated from petroleum polluted soil for petroleum biodegradation. Hexadecane and naphthalene were used to incubate with Acinetobacter calcoaceticus Aca13. After incubation, the whole transcriptome was obtained from treated groups and control groups, and then used for RNA sequence and analysis. Obtained data in this project will help us understand the biodegradation mechanism of hexadecane and naphthalene, and will be helpful for the bioremediation of petroleum hydrocarbons.

Expression analysis of zebrafish liver after exposure in naphthalene

Project description:Investigation of whole genome gene expression level changes in zebrafish liver under naphthalene treatedï¼?high-concentration group and low-concentration groupï¼?, compared to the solvent control group revealed that 76 genes and 88 genes were differentially expressed respectively in the fish caged at the low-concentration and high-concentration. KEGG pathway and GO analysis of the differentially expressed genes, showed significant enrichment in several meaningful categories. Healthy 5-month-old adult zebrafish (AB strain) maintenance and chemical exposure to 84Î¼g/L and 840Î¼g/L naphthalene and 0.005% Dimethyl sulfoxide as the solvent control were performed according to published research protocols. Prior to exposure, the fish were acclimatized in 50L aerated fresh water in glass tanks for 2 weeks, under controlled environmental conditions with the water temperature maintained at 26Â±0.5â?? for 16-h light and 8-h dark photoperiod. After 21 d of treatment, adult zebrafish livers were removed by dissection, and immediately transferred to RNA-later Stabilization Reagent(Qiagen,76106) , prior to storage at 4â?? for histopathological and microarray analysis. NimbleGen Gene Expression 12X135K zebrafish microarrays and One-Color DNA labeling Kit (NimbleGen, WI) were used for genome-wide expression analysis of naphthalene-treated zebrafish.
