Long noncoding RNA UCA1 promotes osteosarcoma metastasis through CREB1-mediated epithelial-mesenchymal transition and activating PI3K/AKT/mTOR pathway.

Increasing evidences have demonstrated that Long noncoding RNAs (lncRNAs) are key regulatory RNAs that participate in multiple biological processes. LncRNA urothelial carcinoma-associated 1 () is a newly identified lncRNA and functions as a regulator of growth in several cancers. However, the biological function and molecular mechanism of in the metastasis of osteosarcoma remain unclear.
