*4.5. Statistical Analysis*

Real-time PCR was carried out in triplicate and cell viability assays were made in quintuplicate in three independent experiments. Western blots are representative of at least three independent experiments. For all data, *n* corresponds to the number of independent experiments. A statistical analysis was performed using SPSS software (IBM Corporation, Armonk, NY, USA). Statistical significance was determined using ANOVA analyzes with Tukey HSD post-hoc tests to compare the treated groups (6 h, 24 h and 48 h) with their appropriate control group (6 h, 24 h and 48 h) and to calculate the significant difference between mono- and co-cultures. The data are shown as mean ± standard deviation (SD). Statistical significance was set at *p* value < 0.05.
