DIAPH2 and gastric cancer: Specifically, in GC, Li et al. identified that the 385–815nt fragment of lncRNA DIAPH2-AS1 bound to the 462–614aa region of NSUN2, masking the K577 and K579 ubiquitination sites and inhibiting ubiquitin-proteasome-mediated degradation to stabilize NSUN2, thus sustaining GC progression [73].
