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.

Description

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].

IC50 & Target

Microbial Metabolite

 

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)

Apoptosis Analysis[2]

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.
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[5].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
