Furthermore, miR-338-3p overexpression reversed the stimulatory effect of EGFR on breast cancer cell migration and invasion as well as EMT (Figures 5d–f), and the inhibitory effect of miR-338-3p on these phenotypes could be rescued by EYA2 overexpression (Supplementary Figures S6A–C). The gene discussed is EGFR; the disease is breast cancer.
