Influence Of Maternal Age On The Effects Of Organic Selenium In The Animal Model Daphnia Pulex, Jordan E. Roberts

All ETDs from UAB

As a necessary micronutrient, seleno-L-methionine (SeMet) exhibits a U-shaped dose-response with deficiency and toxicity leading to adverse health outcomes. Some studies suggest dietary selenium may offer protection against toxicity from other metals, but excessive dietary levels can also lead to toxicity. In addition, increased maternal age has been shown to increase the risk of adverse developmental outcomes. We hypothesize that older maternal age will increase susceptibility in offspring exposed to toxic concentrations of SeMet. The goal of this project was to evaluate the effects of SeMet treatment on lifespan and determine if the effects are altered by maternal age using …
