Caenorhabditis elegans: A promising contrivance to study neurotoxicity and oxidative stress

Abstract

Owing to ubiquitous distribution, high abundances and ecological relevance, Caenorhabditis elegans has strong potential interest as barometer of environment and human health. Ecotoxicological methods are used to evaluate the effect of various anthropogenic contaminants on the ecosystems that circumscribe both in-vivo and in-vitro toxicities to explore the pathways and mechanisms of toxicity and to set precise toxicity thresholds. The interest in C. elegans, as a model organism in toxicological studies, has increased over the past few decades. The enticement of C. elegans comes from the ease of metabolically active digestive, sensory, endocrine, neuromuscular, reproductive systems and genetic manipulation along with the ability to fluorescently label neuronal subtypes. The study reviews the competence of Caenorhabditis elegans as a potential model organism in various toxicity assays specifically neurotoxicity and oxidative stress.
