Abstract

The illegal use of synthetic anesthetic ketamine in adolescents and young adults is high. Also, it is important to mention its therapeutic use by depressive patients who do not respond to the conventional antidepressants drugs, besides the illegal use by health professionals due to the easiest access to obtain this anesthetic. Moreover, it is noteworthy the ubiquity of alcohol and its high consumption in Brazil, especially during adolescence, being consumed along with other substances, such as new psychotropic drugs (e.g. ketamine), which can cause irreversible damage to the central nervous system due to dangerous combinations. Thus, the aim of this study is to investigate the mechanisms underlying cell death after the exposure to ketamine (KT), ethanol (EtOH) and the KT-EtOH combination using SH-SY5Y human neuroblastoma cell culture. Concentration-response curves for the substances will be performed using cell viability assays (XTT, LDH and annexin / propidium iodide - flow cytometry). Proteins involved in the intrinsic (caspase-9, Bax and Bcl-2) and extrinsic (caspase-8 / 10) apoptosis; caspase-3/-7; cleaved and non-cleaved PARP-1; apoptosis independent of the caspase activation (AIF and ENDOG) and the autophagic process (LC3-II) will be evaluated. Methods described in this project include western blot, flow cytometry and immunofluorescence. (AU)
