The Effect Of Cadmium On Ovarian Adenocarcinoma Cell Lines: An Investigation Of The Possible Mechanism Of Action, Haley Todd
Undergraduate Theses
Cadmium, a heavy metal and carcinogen, is an environmental and workplace contaminate. As a known endocrine disruptor, it can mimic the proliferative effects of estrogen and is classified as a metalloestrogen. While the proliferative effect of estrogen on cancerous cell growth has been well established, the effects of cadmium have not been fully examined. To determine if cadmium stimulates growth in two human ovarian adenocarcinoma cell lines, OVCAR3 and SKOV3, cells were treated for 48 hours with varying concentrations of cadmium, 0.001 µM – 10 µM, and growth was measured using a cell proliferation assay. Both cell lines showed a …
Determining The Role Of Erbeta In The Activation Of Erk1/2 By The Environmental Estrogens, Cadmium Chloride And Sodium Arsenite, In Human Lung Adenocarcinoma Cells, Jeffrey Hyzer
Undergraduate Theses
Estrogen is involved in the proliferation of adenocarcinoma lung cells. However, the proliferative role of two endocrine disrupters, cadmium chloride and sodium arsenite, in lung adenocarcinoma is less clear. Previous studies have shown that these two heavy metals can induce cellular proliferation and activate phosphorylation of ERK1/2 in a human lug adenocarcinoma cell line, NCI-H1793. Induced phosphorylation of ERK1/2 by these compounds is decreased in the presence of an estrogen receptor antagonist, ICI-182,780, suggesting that cadmium and arsenite stimulate these responses, in part, via a non-genomic estrogen signaling pathway. There are three known estrogen receptors, but it is unclear which …
