*2.6. Statistical Analysis*

Results of the experiments were expressed as mean ± SEM. GraphPad Prism version 6.04 for Windows (GraphPad Software, San Diego, CA, USA) was used to perform statistical analyses. Results were analyzed using one-way ANOVA followed by Tukey's test, or the two-tailed Student's *t*-test, depending on the experiment. Significant differences shown by an asterisk were considered when *p* < 0.05.
