7,8-Dihydroneopterin is a heterocyclic pteridine which produced and secreted by monocytes/macrophages upon stimulation with the cytokine interferon-y (IFN-y).
7,8-Dihydroneopterin (0.1, 0.5, 1, 2.5, 5 mM; 2 days and 5 days) inhibits growth of U373MG astroeytes .
Cell Viability Assay
Cell Line: |
Astrocytic cell line U373MG |
Concentration: |
0.1, 0.5, 1, 2.5, 5 mM |
Incubation Time: |
2 days and 5 days |
Result: |
After 2 days of treatment, a significantly lower cell number was observed for those cells treated with 5 mM and 2.5 mM.
After incubation for 5 days concentrations of 1-5 mM completely abrogated acid phosphatase activity to background level found for complete cell culture medium.
A significant cell growth inhibition was also visible for the cells incubated with 0.5 mM, whereas 0.1 mM did not alter cell growth. |
