Transcriptomics of selenium toxicity and deficiency in C. elegans (374.1)

Selenium Deficiency and Toxicity in the Environment

[Selenium deficiency and brain functions: the significance for methylmercury toxicity].

Selenium has been long recognized as one of the essential trace elements. Although many selenoproteins have been identified in the last decade, the physiological roles of Se and selenoproteins remain to be elucidated. Since iodothyronine deiodinases (DIs), which regulate the tissue levels of thyroid hormone, are (likely to be) selenoproteins, Se might have specific roles for developing brain. I...

The C. elegans model in toxicity testing

Caenorhabditis elegans is a small nematode that can be maintained at low cost and handled using standard in vitro techniques. Unlike toxicity testing using cell cultures, C. elegans toxicity assays provide data from a whole animal with intact and metabolically active digestive, reproductive, endocrine, sensory and neuromuscular systems. Toxicity ranking screens in C. elegans have repeatedly bee...

Transcriptomics in developmental toxicity testing

Reproductive toxicity testing is one of the most complex, expensive and labor intensive fields of toxicology (Leist et al. drastically demonstrate the fundamental importance of reliable developmental toxicity tests for human safety (van Recently, human embryonic stem cell based in vitro test systems have been established that recapitulate critical periods of human early development (Krug et al....
