Long noncoding RNA host gene 16 (SNHG16) has a key role in a variety of cancer progression. However, the role and mechanism of SNHG16 in osteosarcoma (OS) remain unknown. In this study, we examined the functional role of SNHG16 in OS cells through knocked-down SNHG16 by using siRNA. We found that SNHG16 is overexpressed in OS tissues and cell lines. Inhibition of SNHG16 reduced OS cells proliferation, stimulated apoptosis, and decreased migration and invasion. In addition, SNHG16 reduced miR-340 expression in OS cells. The results showed that SNHG16 involves in the migration and invasion of OS cells through sponging miRNA-340. Together, our data support an important role of SNHG16 in regulating OS cell invasion and migration that highlights SNHG16 may be regarded as a potential target for OS treatment.
