INTRODUCTION: Long non-coding RNAs (lncRNAs) are aberrantly expressed in many
diseases including cancer. LncRNA HULC (highly up-regulated in liver cancer) has
recently been revealed to be involved in hepatocellular carcinoma development and
progression. However, the role and function of HULC in human osteosarcoma remains
unknown. METHODS: LncRNA HULC expression in osteosarcoma tissues and cell lines
was detected by quantitative real-time PCR. Then, the association of HULC level
with survival of osteosarcoma patients was performed by the Kaplan-Meier and Cox
proportional regression analyses. Furthermore, the effects of HULC on
tumorigenicity of osteosarcoma cells were evaluated by in vitro assays. RESULTS:
In the present study, we demonstrated that HULC was significantly up-regulated in
osteosarcoma tissues and cell lines compared with normal controls, and
over-expression of HULC was correlated with clinical stage and distant
metastasis. Moreover, higher HULC expression was associated with shorter overall
survival of osteosarcoma patients. Furthermore, decreased expression of HULC
markedly suppressed osteosarcoma cell proliferation, migration, and invasion.
CONCLUSIONS: Our results indicated that HULC is a novel molecule involved in
osteosarcoma progression, which may provide a new marker of poor prognosis and a
potential therapeutic target for osteosarcoma intervention.
