Prevention of lymphoma was vitamin K2 dependent. Testing the ability of VK2 to reduce recurrence of lymphoma. Follow-up of second-generation flies fed on VK2, divided into two groups: one group continuously reared on VK2 medium and the other on ordinary control medium. (A) Reappearance of black spots after stopping VK2 treatment. The percentage of larvae with recurrent spots very high. (B) Pupal pip out rate of adult flies decreased after stopping VK2 treatment. (C) ROS expression clearly increased after stopping VK2 treatment, recurrence of ROS release was significant. DAPI stain (blue) and ROS staining (CM-H2DCFDA) (green). (D) Inhibition of ATP production after stopping VK2 treatment, decrease in ATP production was significant. DAPI stain (blue) and anti-ATP antibodies (ATP5A). Control media contain 50 mM Ethanol (EtOH) and treatment media contain 50 mM VK2. Means normalized to control (Canton S). Error bars indicate SEM. Analysis of variance (ANOVA/Dunnett: *P < 0.05, **P < 0.01, ***P < 0.001).
