Figure 3From: Cocaine induces cell death and activates the transcription nuclear factor kappa-b in pc12 cellsEffect of cocaine (COC) (1 mM, 6 hours) on DNA fragmentation in PC12 Cells. A flow cytometric analysis was conducted after the cells had been incubated for 6 and 24 hours with cocaine. Results are expressed as mean + S.E.M. from three individual experiments. * p < 0.05 vs PBS (one-way ANOVA followed by Newman-Keuls test).Back to article page
