Figure 3. Cadmium does not induce apoptosis in p53-deficient PC3 and DU145 prostate cancer cell lines.

Cadmium effects on PC3 (A–D) and DU145 (A′–D′) cells, after 24-h treatment with different concentrations of CdCl₂ (0, 10, 20 and 30 µM). Same conditions as in figure 1. Scale bars in A, A′: 100 µm. * P<0.05.
