Wilms tuber 1-associated protein (WTAP) maintains the stability of lncRNA DIAPH1-AS1 in an m6A-dependent manner, promotes the formation of MTDH-LASP1 complex, protects LASP1 from ubiquitin degradation, and promotes the growth and metastasis of NPC (98). Here, MTDH is linked to nasopharyngeal carcinoma.
