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.
Cell Viability Assay
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 IC 50 (1-90 μM) at 72 h than normal prostate cells (>500 μM). |
Apoptosis Analysis
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
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
Cell Line: | Human thyroid epithelial cells (HTori-3) |
Concentration: | 5 μM |
