SSX2IP and ovarian carcinoma: <i>SSX2IP</i> (Synovial Sarcoma, X Breakpoint 2 Interacting Protein) was confirmed to be the direct gene target of miR-625-3p and its upregulation abrogated miR-625-3p-mediated cisplatin resistance by enhancing the EV export of cisplatin in ovarian cancer cells.<h4>Conclusions</h4>These findings provide a new paradigm for intrinsic cisplatin resistance acquisition by HGSC cells, which will be crucial for developing new treatment strategies for ovarian cancer based on the upregulation of miR-625-3p or downregulation of SSX2IP to enhance cisplatin sensitivity and improve patient survival rates.
