Figure 1: miRNA expression profile in exfoliated cells of the tongue in GERD and Ctrls. qRT-PCR expression levels of miR-143 (a), miR-145 (b), miR-192 (c), miR-194 (d), miR-203 (e), and miR-205 (f) in patients with GERD () and healthy donors (Ctrls, ). The median level of expression is represented in each group by a solid line. The values are normalized to U6 expression levels and displayed in log 10 scale on -axis.
