Aberrant function of
RRAS2
drives malignant transformation in a various of cancers. However, little information exists on the function of
RRAS2
in tumorigenesis of
osteosarcoma
. In this study, we investigated the effect of
RRAS2
on
osteosarcoma
progression and its underlying mechanism. The gene expression level and prognostic power of
RRAS2
in
osteosarcoma
were first investigated using the data from the Gene Expression Omnibus database. Then RNA interference was performed to silence the expression of
RRAS2
in
osteosarcoma
cells. Quantitative real-time-PCR and western blot were used to examine the gene and protein expressions of
RRAS2
in
osteosarcoma
cells. In-vitro cancer proliferation and migration were determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolum bromide solution and wound-healing assays, respectively. We found that
RRAS2
was significantly upregulated in
osteosarcoma
cells and high expression of
RRAS2
was associated with a poor prognosis for patients with
osteosarcoma
. RNA interference decreased the gene and protein expression of
RRAS2
, reduced in-vitro the proliferation and migration of
osteosarcoma
cells, and suppressed the activation of the MEK/ERK signaling pathway.
RRAS2
as an adverse prognostic factor promoted cell proliferation and migration by activating the MEK/ERK signaling pathway, and may provide new therapeutic value for
osteosarcoma
.
