Effect of CTX on the survival of rat C6 glioma cells. The cells were incubated in the presence of various CTX concentrations (3 pM–3 μM) for 72 h. Cytotoxin I (Cyt I) from Naja oxiana venom was used for a positive control. The cell viability was determined by MTT test. Data are shown as % of control (untreated cells). The results are presented as the mean ± SEM in three (for concentrations of 3 nM and 300 pM—four) independent experiments with 12 replicates in each. * p < 0.05, Student’s two-sample t-test compared to control.
