FIG. 2.

Cd uptake by HeLa cells. Cells cultured in 96-well or 6-well plates treated with Cd as indicated amounts and time were analyzed for Cd measurement by fluorescence plate reader. The amount of Cd left in medium was quantified (A) and increased Cd levels in cells (B) were shown as % of control. In some studies, cells were pretreated with Cyt D for 30min before Cd exposure for 4h to test Cyt D effect on Cd uptake. Data in bar chart represent means ± SE of eight measurements for (A) and three measurements for (B) using three different experiments. *p < 0.05 vs. control group.
