Oxidative Stress and Mitogen-Activated Protein Kinase Pathways Involved in Cadmium-Induced BRL 3A Cell Apoptosis

Figure 7

Relative quantification of Bax and Bcl-2 gene expression levels by real-time PCR in relation to β-actin. Cells were treated with 0 μmol/L to 40 μmol/L for 12 h. Data are presented as mean ± SD of three independent experiments performed in triplicate. Significant difference: *𝑃<0.05, **𝑃<0.01, compared with the control; ^#𝑃<0.05, ^##𝑃<0.01, compared with the 20 μmol/L Cd group.
