*4.7. Statistical Analyses*

All treatments and experiments in this study had at least three independent biological and technical replicates. The mean values are presented in graphs drawn using the GraphPad Prism 5 software, while standard deviations are represented as error bars. One-way analysis of variance (one-way ANOVA) and Tukey0 s HSD test were carried out to assess the significant variations existing between the treatments and analyses performed in this study. Statistics by ANOVA test are shown; \* *p* < 0.05, \*\* *p* < 0.001, and \*\*\* *p* < 0.0001. Pearson correlation coefficients and their significance were measured using the Social Science Statistics [47].
