FIG. 2.

Cadmium 50μM does not appear to induce necrotic cell death in Calu-3 cells. (A) Calu-3 cells were exposed to 50μM cadmium for 3 days. Cadmium cytotoxicity was evaluated by measuring LDH release in the culture medium as described in “Materials and Methods” section. Data are expressed as mean ± SEM of four independent experiments. (B) Calu-3 cells were exposed to 10–200μM cadmium for 4 days. Cell viability was evaluated using the MTT assay as described in “Materials and Methods” section. Data are expressed as mean ± SEM of at least three independent experiments.
