| Osteosarcoma (OS) is the most common primary malignant tumor of the bone
with a strong tendency to early metastasis, and occurs in growing bones more
commonly in children and adolescents. Considering the limited therapeutic
methods and lack of 100% success of these methods, developing innovative
therapies with high efficacy and lower side effects is needed. Meanwhile,
miRNAs and the studies indicating the involvement of miRNAs in OS
development have attracted attentions as a result of the frequent abnormalities
in expression of miRNAs in cancer. miRNAs are noncoding short sequences
with lengths ranging from 18 to 25 nucleotides that play a very important role in
cellular processes, such as proliferation, differentiation, migration, and
apoptosis. MiRNAs can have either oncogenic or tumor suppressive role based
on cellular function and targets. This review aimed to have overview on miR‐
142 as a tumor suppressor in OS. Moreover, the genes involved in the disease,
such as RAC1, HMAG1, MMP9, MMP2, and E‐cadherin, which have
irregularities as a result of change in miR‐142 expression, and, thereby, result
in increasing the proliferation, invasion, and metastasis of the cells in the
tissues and OS cells will be discussed. |
