Figure 1.

Dose- and time-dependence cell viability due to the addition of GaMal and InMal alone or each one co-incubated with MTX (10 or 200 ng mL^–1) (Experiment 1, see Experimental Section) on both MDA-MB-231 (a–f) and NIH-3T3 (g–l), respectively. Results of MTT test are expressed as percentage related to untreated cells (no metal complexes or MTX addition) set as 100%. Bars represent the mean values ± SEM (standard error of the means) of results from three experiments (n = 3, p < 0.05).
