DNA Damage and Inhibition of Akt Pathway in MCF-7 Cells and Ehrlich Tumor in Mice Treated with 1,4-Naphthoquinones in Combination with Ascorbate

Figure 4

Antitumor actions of juglone, Q7, and Q9 administered in combination with ascorbate against MCF-7 cells and Ehrlich ascites carcinoma in mice. The effects are the result of intercalation and oxidative attack on DNA of tumor cells and inhibition of Akt pathway.
