The BC- and CBD-treated rats showed increased SOD2, as noted by brown staining in Figure 9A. The histogram in Figure 9B shows the relative levels of SOD2 in the stained sciatic nerves in Figure 9A. In the SD diabetic rat sciatic nerves, the SOD2 (p < 0.001) protein declined significantly, while the treatments with BC, CBD, or a combination resulted in a significant restoration of the SOD2 levels in the sciatic nerves (9B). This evidence concerns the gene SOD2 and breast cancer.
