生物活性

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[1][2][3].

体外研究
(In Vitro)

L-SelenoMethionine (1-500 μM; 24-72 h) is selectively inhibits the growth of prostate cancer cells, compared with normal cells[2].
L-SelenoMethionine (500 μM; 48 h) induce apoptosis in prostate cancer cells[2].
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[2].
L-SelenoMethionine (5 μM; 24 h) mitigates gene expression associated with the cellular stress response from 10 cGy irradiation[4].

Cell Viability Assay[2]

Cell Line: Prostate cancer cells (LNCaP, PC-3, and DU145) and normal prostate cells (PrEC, PrSM, and PrSt)
Concentration: 1, 5, 10, 50, 100, 500 μM
Incubation Time: 24, 48, 72 hours
Result: Inhibited the growth of prostate cancer cells, with a lower IC50 (1-90 μM) at 72 h than normal prostate cells (>500 μM).

Apoptosis Analysis[2]

Cell Line: Prostate cancer cells (LNCaP, PC-3, and DU145) and normal prostate cells (PrEC, PrSM, and PrSt)
Concentration: 500 μM
Incubation Time: 48 hours
Result: Exhibited the highest level of DNA condensation in androgen-responsive LNCaP carcinoma cells, followed by PC-3 and DU145 cells.
Exhibited the nicked-end DNA labeling in prostate cancer cells.
Promoted the PARP cleavage in prostate cancer cells.

Cell Cycle Analysis[2]

Cell Line: Prostate cancer cells (LNCaP, PC-3, and DU145) and normal prostate cells (PrEC, PrSM, and PrSt)
Concentration: 500 μM
Incubation Time: 48 hours
Result: Increased the sub-G0-G1 cell fraction of LNCaP (41.5%), PC-3 (12.1%), and DU145 cells (11.2%).
Caused a significant increases in G2 cells , particularly in LNCaP (13%), PC-3 (32%), and DU145 (20%) cells.

RT-PCR[3]

Cell Line: Human thyroid epithelial cells (HTori-3)
Concentration: 5 μM
Incubation Time: 24 hours
Result: Downregulated the CDC6, GADD45A, FAS and ATF3 in irradiated cells.
