Figure 2.
Effect of biogenic amines on HCT116 and MCF7 cell viability. MCF7 and HCT116 cells were grown for 24 or 48 h in serum-free medium in presence of scalar doses of biogenic amines serotonin, dopamine, or histamine. Viabilities were assessed by MTT assay and presented as the percentage of viable cells vs. control. Data show mean ± SD of one representative experiment out of three independent experiments performed in quadruplicate.
