Effect of alcohol on energy storage of primary astrocytes and C6-glioma cells in vitro

The present experiments were conducted to investigate the direct effects of ethanol on the energy metabolism of astrocytes and C6-glioma cells. Primary astrocytes were prepared from cerebral cortices of neonatal rats, and C6-glioma cells were purchased from American Type Culture Collection (ATCC). T...

Zusammenfassung:The present experiments were conducted to investigate the direct effects of ethanol on the energy metabolism of astrocytes and C6-glioma cells. Primary astrocytes were prepared from cerebral cortices of neonatal rats, and C6-glioma cells were purchased from American Type Culture Collection (ATCC). These cells were exposed to different concentrations of alcohol (100 mM, 200 mM, and 300 mM) for 15 minutes and 24 hours. The amount of ATP and PCr was measured by the method of Lowry and Passonneau (1972). Following 15 minutes treatment with different doses of ethanol the amount of ATP and PCr increased, in both cell types. Only the increase of ATP concentration with varying doses of ethanol (100 mM, 200 mM, and 300 mM) was statistically significant. Following 24 hours treatment of astrocytes with different doses of ethanol the concentration of ATP and PCr decreased. The decrease in concentration of ATP was significant with all three doses of ethanol, but the decrease of PCr concentration was only statistically significant with 300 mM ethanol. Following 24 hours treatment of C6-glioma cells to varying doses of ethanol, the concentration of PCr and ATP decreased. The decrease of PCr was statistically significant with all three doses of ethanol and the decrease of ATP concentration was only significant with 300 mM ethanol.
