Figure 3.

In vitro viability assessment of RhodOA and rhodamine B (20, 40, 60, 80 and 100 nM) after 72 h in HaCaT human keratinocytes, A375 human melanoma, A549 human lung adenocarcinoma and MDA-MB-231 human breast adenocarcinoma cell lines. The results are expressed as cell viability percentage (%) normalized to control (DMSO-stimulated) cells. The data represent the mean values ± SD of three independent experiments performed in triplicate. One-way ANOVA analysis was applied to determine the statistical differences in rapport with DMSO followed by Dunnett's multiple comparisons post-test (*P<0.05, **P<0.005, ***P<0.001, ****P<0.0001). DMSO, dimethyl sulfoxide.
