Abstract/OtherAbstract:
Tricyclodecan-9-yl-xanthogenate (D609) has been shown to possess both neuroprotective and anti-proliferative properties. We investigated the role of D609 in reducing the proliferation of neural progenitor cells in vitro. D609 decreased the expression of cyclin D1 after 1 day but not 2 or 4 days in culture, indicating the possible degradation/inactivation of drug in the medium. Consistent with this notion, spectral analysis showed the maximum absorbance of D609 (100 μM) at 300 nm, which decreased by ~30 % following incubation at 37 °C for 24 h. Further experiments revealed that incubation of neural progenitor cells with D609 decreased the phosphorylation of extracellular signal-regulated kinase (ERK) but not Akt. In addition, increasing the concentration of B27 (1-4 %), but not FGF2, diminished the effect of D609 on cell proliferation. These results together suggest that D609 may curtail the proliferation of neural progenitor cells by decreasing the ERK-mediated expression of cyclin D1 and may have a therapeutic potential in containing the proliferation of tumor stem cells.
