*4.7. Data and Statistical Analyses*

The data and statistical analyses used in this study comply with the recommendations on experimental design and data analysis in pharmacology [45]. Quantitative results are shown as mean ± SEM of *n* observations. To compare two sets of data, Student's *t*-test was used, and differences considered to be significant for *p*-values ≤ 0.05. In Western blotting (Figures 1–3), pulse chase (Figure 4 and Figure S2); cell surface biotinylation (Figure 4) and in iodide efflux studies (Table 1, Figure 5, Figures S3 and S4), n represents the number of experiments performed with distinct cell cultures on different days, being thus biological replicates.
