In the present study, we investigated the role of LINC00852/miR-140-3p/AGTR1 pathway in ovarian cancer, and found LINC00852 acted as a ceRNA of miR-140-3p to repress miR-140-3p expression thereby promoting AGTR1 expression to promote the growth and invasion of ovarian cancer in vitro and in vivo. The gene discussed is LINC00852; the disease is ovarian cancer.
