This book was released on 2015 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Performance-Based Test Guideline (PBTG) describes in vitro assays, which provide the methodology of Stably Transfected Transactivation to detect Estrogen Receptor Agonists and Antagonists (ER TA assays). It comprises mechanistically and functionally similar test methods for the identification of estrogen receptor agonists and antagonists and should facilitate the development of new similar or modified test methods. The two reference test methods that provide the basis for this PBTG are: the Stably Transfected TA (STTA) assay using the (h) ERÎł-HeLa-9903 cell line, derived from a human cervical tumor, and the BG1Luc ER TA assay using the BG1Luc-4E2 cell line, derived from a human ovarian adenocarcinoma. The cell lines used in these assays express ER and have been stably transfected with an ER responsive luciferase reporter gene. The assays are used to identify chemicals that activate (id est act as agonists) and also suppress (id est act as antagonists) ER- dependent transcription. ER are activated following ligand binding, after which the receptor-ligand complex binds to specific DNA response elements and transactivates the reporter gene, resulting in increased cellular expression of a marker enzyme (e.g. luciferase in luciferase based systems). The enzyme then transforms the substrate to a bioluminescent product that can be quantitatively measured with a luminometer. These test methods are being proposed for screening and prioritisation purposes, but also provide mechanistic information that can be used in a weight of evidence approach.

Available in PDF, EPUB and Kindle. Book excerpt: Hayes’ Principles and Methods of Toxicology has long been established as a reliable reference to the concepts, methodologies, and assessments integral to toxicology. The new sixth edition has been revised and updated while maintaining the same high standards that have made this volume a benchmark resource in the field. With new authors and new chapters that address the advances and developments since the fifth edition, the book presents everything toxicologists and students need to know to understand hazards and mechanisms of toxicity, enabling them to better assess risk. The book begins with the four basic principles of toxicology—dose matters, people differ, everything transforms, and timing is crucial. The contributors discuss various agents of toxicity, including foodborne, solvents, crop protection chemicals, radiation, and plant and animal toxins. They examine various methods for defining and measuring toxicity in a host of areas, including genetics, carcinogenicity, toxicity in major body systems, and the environment. This new edition contains an expanded glossary reflecting significant changes in the field. New topics in this edition include: The importance of dose–response Systems toxicology Food safety The humane use and care of animals Neurotoxicology The comprehensive coverage and clear writing style make this volume an invaluable text for students and a one-stop reference for professionals.

Download or read book OECD Guidelines for the Testing of Chemicals Section 4 Test No 442E In Vitro Skin Sensitisation In Vitro Skin Sensitisation assays addressing the Key Event on activation of dendritic cells on the Adverse Outcome Pathway for Skin Sensitisation written by OECD and published by OECD Publishing. This book was released on 2024-06-25 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present Key Event based Test Guideline (TG) addresses the human health hazard endpoint skin sensitisation, following exposure to a test chemical. Skin sensitisation refers to an allergic response following skin contact with the tested chemical, as defined by the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (UN GHS). This TG is proposed to address the activation of dendritic cells, which is one Key Event on the Adverse Outcome Pathway (AOP) for Skin Sensitisation. It provides four in vitro test methods addressing the same Key Event on the AOP: (i) the human cell Line Activation Test or h-CLAT method, (ii) the U937 Cell Line Activation Test or U-SENS, (iii) the Interleukin-8 Reporter Gene Assay or IL-8 Luc assay and (iv) the Genomic Allergen Rapid Detection for assessment of skin sensitisers (GARDTMskin). All of them are used for supporting the discrimination between skin sensitisers and non-sensitisers in accordance with the UN GHS. The test methods described in this TG either quantify the change in the expression of cell surface marker(s) CD54 and CD86, the cytokine IL-8, or a series of genes (genomic biomarker signature) that are associated with the process of activation of monocytes and DC following exposure to sensitisers.
