资料参考

Menadione (vitamin K3), used as a nutritional supplement, is an inhibitor of mitochondrial DNA polymerase γ (pol γ), with an IC 50 value of 6 μM [1].

Pol γ is responsible for all aspects of mitochondrial DNA synthesis, including all replication, recombination of the mitochondrial genome, and repair of mitochondrial DNA damage [1].

In the extract of mitochondrion fraction from HCT116 (p53+/+ andp53–/–) cells, menadione at 30 μM inhibited pol γ by more than 80%. In HCT116 cells, 30 μM menadione also caused impairment of mitochondrial DNA replication and repair, and triggered a significant increase in reactive oxygen species (ROS), leading to apoptosis. At a lower concentration of 3 μM, menadione did not significantly increase the ROS level, but was able to effectively inhibit cancer cell proliferation, which could be reversed by supplementing glycolytic substrates [2].

In Emory mice, menadione at a low non-toxic dose of 0.12% (w/w), used as a dietary supplement for 10 to 12 weeks, caused early signs of cataract, such as prominent anterior suture, in 68% of the Emory mice [3].

Cell lines

HCT116p53+/+andp53–/–cells

Reaction Conditions

3 or 30 μM menadione for 24 h incubation

Applications

Menadione at 30 μM inhibited DNA polymerase γ by more than 80%, caused impairment of mitochondrial DNA replication and repair, and induced a significant increase in reactive oxygen species (ROS), leading to apoptosis. At a lower concentration (3 μM), menadione did not cause a significant increase in ROS, but was able to effectively inhibit cell proliferation, which could be reversed by supplementing glycolytic substrates.

By oral route for 10 to 12 weeks

Applications

In Emory mice, menadione at a low non-toxic dose (0.12%, w/w), used as a dietary supplement for 10 to 12 weeks, caused early signs of cataract, such as prominent anterior suture, in 68% of the Emory mice.
