- Abstract: Objetivo: Drug abuse is associated with changes in brain function and neurodegenerative process, which, for some drugs, have been shown to be associated with the induction of apoptotic cell death. Cocaine is a widely used drug of abuse and a psychostimulant that acts on the central nervous system by blocking dopamine reuptake sites. NF-_B is a transcription factor which plays an important role in the control of the immunity, inflammation and apoptotic response. Our aim was to evaluate if cocaine can modulate NF-_B in PC 12 cells. Métodos e Resultados: PC 12 cells which was cultured in dishes were treated with increasing concentrations of cocaine (0,05; 0,25; 0,5; 0,75; 1,0mM) for 8 hours. Nuclear extracts were isolated and gel mobility shift assay used to measure changes in NF-_B activity. Competition studies with specific and nonspecific unlabeled double-strand oligonucleotide were also performed. Cocaine (0,75 and 1,0 mM) induced a significant induction of NF-_B in PC 12 cells. This activation was dose dependent. Conclusões: Our results suggest that cocaine induces a dose-dependent activation of NF-_B in PC 12 cells.
