ZNF77 and ovarian cancer: To assess whether the tumor-suppressive functions of miR-550a-3p could be extended to models of tumor types other than DMPM, we ectopically expressed miR-550a-3p in two ovarian cancer (IGROV-1 and its platinum-resistant derivative IGROV-1/Pt1) and two prostate cancer (DU145 and PC3) cell lines (Fig. 3A, p < 0.05).
