Osteosarcoma is the most common bone cancer in children and adults. However, its
pathogenesis, especially molecular mechanisms remain elusive. In current study,
we screened GEO Database and found a poorly studied protein Neurensin-2 (NRSN2),
which is highly expressed in osteosarcoma tissues. Neurensin-2 (NRSN2) is a small
neuronal membrane protein and localized in small vesicles in neural cells,
previous study found that it has been implicated in hepatocellular carcinoma
(HCC) and non-small cell lung cancer (NSCLC). We here report that the expression
of NRSN2 is more commonlyelevated in 18 fresh osteosarcoma tissues. Furthermore,
both loss- and gain-functions assays revealed that NRSN2 could promote
osteosarcoma cell proliferation and growth both in vitro and in vivo. In
addition, we further found that those effects on osteosarcoma by NRSN2 are
associated with the dysregulated PI3K/AKT/mTOR signaling and Wnt/?-catenin
signaling. In conclusion, our study found a novel oncogenic protein, NRSN2, which
promotes osteosarcoma cell proliferation and as a membrane protein, NRSN2 also
could be a potential treatment target for osteosarcoma.
