FZD4 and ovarian carcinoma: Upregulation of HOXD-AS1 expression in ovarian cancer (OC) competitively binds miR-608, an inhibitory miRNA of Fzd4, in vitro and in vivo, leading to high Fzd4 expression that correlates with ovarian cancer cell migration, invasion, and proliferation (Wang et al., 2018b).
