L-SelenoMethionine

L-SelenoMethionine, an L-isomer of Selenomethionine, is a major natural food-form of selenium. L-SelenoMethionin is a cancer chemopreventive agent that can reduce cancer incidence by dietary supplementation and induce apoptosis of cancer cells. L-SelenoMethionine also can increase expression of glutathione peroxidase.

How to use

In Vitro:

L-SelenoMethionine (1-500 μM; 24-72 h) is selectively inhibits the growth of prostate cancer cells, compared with normal cells. L-SelenoMethionine (500 μM; 48 h) induce apoptosis in prostate cancer cells. L-SelenoMethionine (500 μM; 48 h) causes an increase in arrest in the G2-M phase of the cell cycle selectively in prostate cancer cells. L-SelenoMethionine (5 μM; 24 h) mitigates gene expression associated with the cellular stress response from 10 cGy irradiation.

In Vivo:

L-SelenoMethionine (0.06-12 μg/g diet; p.o. for 3 d) partially or completely prevent the decrease in the serum or plasma levels of total antioxidants in rats exposed to gamma rays, protons or HZE particles.
