This book focuses on exposure toxicology in C. elegans. The nematode Caenorhabditis elegans is sensitive to various environmental toxicants and stresses, and has proven to be an important animal model in both molecular and target-organ toxicology. As a result, over the past 30 years, there has been extensive research on the exposure to environmental toxicants or stresses in nematodes. Based on the available data, the book offers an introduction to the exposure system established in nematod...

This book introduces readers to intestinal and epidermal barriers, and to toxicity induction of environmental toxicants or stresses in the intestine, epidermis, neurons, muscle, and reproductive organs in Caenorhabditis elegans. In addition, it discusses the protective responses of various organs and nematodes’ avoidance behaviour with regard to environmental toxicants or stresses. The intestinal, epidermal, neuronal, and germline signalling pathways required for the regulation of...

Nematodes are small multicellular organisms that have been used as biological models since the 1960s. For example, Caenorhabditis elegans is a free-living nematode worm, about 1mm in length, that lives in temperate soil environments. It is made up of about 1000 cells, and has a short life cycle of only two weeks. It was the first multicellular organism to have its whole genome sequenced. The book summarizes the importance of nematodes as model organisms in the fields of genetics, developme...

This book focuses on transgenerational toxicology using Caenorhabditis elegans as a model organism. C. elegans provides a powerful system for assessing toxic effects across generations because of its high sensitivity to environmental exposures and short life cycle. This book systematically presents current knowledge on the mechanisms underlying transgenerational toxicity, including toxicant translocation, biological barriers, intergenerational signaling, metabolic regulation, GPCR and nucl...

This book will focus on the molecular basis of oxidative stress induced by toxicants or stresses and various molecular signalling pathways in regulating the toxicity of toxicants or stresses in Caenorhabditis elegans. It will also cover the discussion on the aspects of response signals, G-protein coupled receptors and ion channels, specific molecular signals, and epigenetic signals involved in the regulation of toxicity from toxicants or stresses. The molecular basis for adaptive ...
