Researchers reported that miR-222-3p expression in ovarian cancer was associated with long time survival; the lower expression of miR-9, miR-595(81), and miR-15b with higher expression of WNT7a [58] were associated with shorter survival, and poor prognosis, in addition, the differences in the expression levels of miR-14 1[59], miR-200a, and miR-200c were reported to be associated with the progression-free survival (PFS). The gene discussed is WNT7A; the disease is ovarian cancer.
