Özet:

 Programmed cell death apoptosis is mainly responsible for neuronal damage in neurodegenerative diseases. Thus, inhibition of apoptosis could represent an effective strategy in the prevention of these diseases. In this study, we aimed to compare the apoptotic responses of neurotoxins that are widely used to induce neuronal damage in cell culture studies and help to decide the most suitable experimental model for drug studies that target apoptosis. Cell viability analyses were performed by MTT assay following 1-methyl-4-phenylpyridinium MPP, 6-hydroxydopamine 6-OHDA, rotenone and paraquat treatments at three different time points 12, 24, 48h. Pro-apoptotic Bax, Bad, Bak, anti-apoptotic Bcl-2, Bcl-xl protein levels and total caspase-3 protein levels were determined by Western Blotting technique following treatments. As expected, all neurotoxins managed to trigger cell death and apoptotic pathway. On the other hand, each neurotoxin was found to enhance andor reduce the levels of different proteins that are associated with apoptosis. Due to different responses of apoptosis related proteins to neurotoxins, it can be concluded that the determination of target proteins with a number of protein-binding assays prior to cell culture studies and then deciding an in vitro model are essential while screening newly synthesized drugs that target apoptosis.
