Fig. 2
Response to 3-BrPA treatment in murine PA28y overexpressing fibroblasts (B8y) and controls (B8vc) in a cell viability assay. c(3-BrPA) – concentration of 3-BrPA; ∆FUnorm – normalized difference of fluorescence units. a Mean values of normalized differences in FU according to Eq. (1). SEM of eight independent experiments are presented. Concentration ranges with significant differences (p < 0.05) in cell viability compared to B8vc cells are marked by horizontal lines and asterisks. b Correlations between cell viability and agent concentration as regression lines.
