OXCT1 and osteosarcoma: This newly reported relationship requires further studies, not only in osteosarcoma but also in other cancer types, especially since the obtained results strongly suggest that overexpression of OXCT1-AS1 and the ratio of full-length vtRNA2-1 and vtRNA2-1/nc886 after processing by Dicer might be useful prognostic parameters in osteosarcoma patients [92,93].
