Figure 1. Thiamine antagonists amprolium, oxythiamine and pyrithiamine affect viability of PC-12 cells in time- and dose-dependent manner.
Viability of neuronally differentiated PC-12 cells was measured using WST-1 reagent and Multiscan RC (Thermolabsystems) upon treatment with 10, 100 or 1000 μM oxythiamine, pyrithiamine or amprolium in serum-reduced media for 48, 72 and 96 h. The viability rates represent the means ± S.E.M. for non-treated cells and cells treated with tested thiamine antagonists in which each value was determined from assays performed in quadruplicate. Further experimental details are given in Materials and Methods.
