Identification of new nasopharyngeal carcinoma (NPC) biomarkers is of great clinical value for the diagnosis and treatment of NPC. HOTAIR, a cancer-related long noncoding RNA, was tested and its prognostic value for NPC was evaluated. Determined by In situ hybridization (ISH), 91 of 160 (56.87%) paraffin-embedded NPC biopsies showed high expression levels of HOTAIR (Staing Index, SI score ≥ 6). HOTAIR was up-regulated in tumors with a larger tumor (p = 0.021), more advanced clinical staging (P = 0.012) and increased lymph node tumor burden (P = 0.005). Quantified by real-time PCR, HOTAIR expression levels in fresh tissue and paraffin-embedded samples were 5.2˜48.4-fold higher compared with non-cancer tissue samples. Moreover, HOTAIR expression levels increased with clinical stage progression, which was consistent with ISH findings in the paraffin-embedded tissue. Most importantly, NPC patients with higher HOTAIR levels had poor prognosis for overall survival by univariate and multivariate analysis. In addition, HOTAIR mediated the migration, invasion and proliferation of NPC cells in vitro. HOTAIR is a potential biomarker for the prognosis of NPC, and dysregulation of HOTAIR may play an important role in NPC progression.
