MACC1 or Met overexpression could increase cell proliferation OD values and cell colony numbers, but those proliferation promotive effects could be attenuated by miR-338-3p overexpression, at least partially (Fig. 3), which showed miR-338-3p could inhibit the proliferation of ovarian cancer cells induced by MACC1 and Met overexpression. The gene discussed is MET; the disease is ovarian carcinoma.
