Effects of acute and chronic lithium treatment on bcl-2 a) mRNA and b) protein levels in rat primary astrocyte, neuronal, and mixed astrocyte-neuronal cultures treated with lithium (1 mM) or vehicle (100 µl sterile distilled water, control) for one day (acute) or 7 days (chronic). Bars indicate the mean±SEM, n=7 independently grown and treated cell lines per group. *indicates P<0.05 compared to vehicle-treated cultures
