Expression of ENO-1 and ENO-2 mRNA and protein in As+3 and Cd+2- transformed MCF-10A cells. Real-time RT-PCR and western blot analysis of ENO-1 mRNA and protein in As+3 and Cd+2- transformed MCF-10A cells (A and C) and ENO-2 (B and D) respectively. Statistical analysis consisted of ANOVA with Tukey post hoc testing performed using GraphPad PRISM 5. *Denotes a statistically significant difference from MCF-10A parent cells (p < 0.05). Real-time data is plotted as the mean ± SEM of triplicate determinations.
