For the first time, they revealed that miR-122 suppressed ovarian cancer cell motility, invasion, EMT, and metastasis in the peritoneal cavity by targeting prolyl 4-Hydroxylase Subunit Alpha 1 (P4HA1), shedding light on the identification of miR-122 and P4HA1 as prospective diagnostic indicators and therapeutic targets for OC [43]. This evidence concerns the gene P4HA1 and ovarian cancer.
