Table 3. Comparison of the expression of each reference gene in HT and non-diseased control biopsies.

3a displays the pvalues from the qPCR experiments. Data were analyzed by Mann-Whitney Asymp. Sig. (2-tailed). None of the comparisons yielded statistically significant results. 3b shows the fold change (FC) differences and Pearson’s correlation in the expression of selected references genes. Fold changes are represented as mean±SD log FC.
