Inhibition of MiR-155 suppresses cell migration in nasopharyngeal carcinoma through targeting ZDHHC2.


PMID 26309499

Abstract

Overexpression of miR-155 in nasopharygeal carcinoma (NPC) is partly driven by Epstein-Bar virus infection. However the role of miR-155 in NPC oncogenesis is unclear. This study showed that miR-155 inhibitor could inhibit the cell migration in NPC cell lines. ZDHHC2 was identified as a direct target of miR-155 and downregulation of ZDHHC2 prompted cell migration in NPC. Furthermore, reduced ZDHHC2 expression was associated significantly with metastasis and poor survival of NPC patients. Collectively, inhibition of miR-155 suppresses cell migration in NPC through targeting ZDHHC2. The potential of miR-155 and ZDHHC2 as therapeutic targets in NPC should be further investigated.
