YBX1 and nasopharyngeal carcinoma: Recent studies have elucidated some mechanisms underlying NPC metastasis and cisplatin chemoresistance, including USP7-mediated stabilization of KDM5B via the ZBTB16/TOP2A axis74, circIPO7-facilitated YBX1 nuclear localization75, and SOX1 drives chemoresistance in nasopharyngeal carcinoma by inducing a therapy-refractory cellular state76.
