For instance, Yan et al reported that lncRNA MLK7‐AS1 was up‐regulated in ovarian cancer tissues and cell lines, and promoted cell proliferation, migration and invasion through binding to miR‐375 and thereby reversing its inhibitory effect on regulating the Yes‐associated protein 1 (YAP1) expression in ovarian cancer.27 Although some ovarian cancer related lncRNAs have been identified, the functional roles of many other lncRNAs in ovarian cancer are still unknown. Here, MAP3K20 is linked to ovarian cancer.
