Molecular, Cellular And Systemic Effects Of Atrazine On The Xenopus Laevis Tadpole, Renee Maryanne Zaya

Dissertations

Atrazine is one of the two most commonly used herbicides in the US and it is the most studies are among the first to link physiological effects of atrazine to changes in tissue and gene expression in Xenopus laevis tadpoles. These studies provide the groundwork for future studies into the mechanisms behind responses to chemical stressors generating data resulting in a better understanding of how these chemicals affect us all. commonly found herbicide in ground water. As a result, a great deal of attention has been placed on its use and safety. It has also been implicated to play a …

Characterization Of Molecular Events Following Heavy Metal Cadmium Exposure: A Cellular Regulatory Symphony In Response To Early Cadmium Insult, Chin-Ju Jean Hsiao

Dissertations

Cadmium, a non-essential toxic heavy metal, has been classified as a human carcinogen and one of the most hazardous substances in our environment. Since it can circulate within the food chain, has a long biological half-life and can bio-accumulate, it has the potential to induce detrimental health effects linked to toxicity, cancer and chronic diseases.

In recent years progress has been made to dissect and understand the molecular mechanisms underlying the effects of cadmium exposure. However, few studies have focused on investigating potential protective and/or defense mechanisms naturally applied by cells upon initial exposure, prior to any damage or toxic …
