Figure 1.

In vitro evaluation of the CdCl₂ effect (0.05; 0.2; 1; 10 and 100 µg/ml) on viability of HT-29 cells at 24 h post-stimulation by the Alamar blue assay. The results are expressed as cell viability percentage (%) normalized to control (unstimulated) cells. The data represent the mean values ± SD of three independent experiments performed in triplicate. One-way ANOVA analysis was applied to determine the statistical differences compared with the control group, followed by Dunnett's multiple comparisons post-test (^*P<0.05 and ^****P<0.0001).
