Figure S3. Vigabatrin abolished the pro-proliferative effect of GABA a., The effect of GABA (5 mM), vigabatrin (0.6 mM) and GABA+vigabatrin on the proliferation of U251 wt glioma cells. SRB and Alamar Blue (AB) proliferation assays were used in 24-h treated cell cultures; b., Alterations in cell numbers (U251 wt cells) followed in every 4-day passage using 3-week continuous treatment, the average cell numbers were calculated from triplicates.
