Figure 1: Cell apoptosis in PC-12 cells after 24 h incubation with 0–60 μmol/L Vit K3. (a) Pseudocolor plot of flow cytometry; (b) at 5–20 μmol/L concentration, cell apoptosis first decreased and then increased with growing concentration from 0 to 20 μmol/L, but there was no statistical significance. However, it increased when concentration was 40 μmol/L (t-test, P < 0.0001) and 60 μmol/L (t-test, P < 0.0001), when each group was compared with 0 μmol/L. *P < 0.05. Vit K3: Vitamin K3.
