We proposed that VRK1 and H2A<sup>T120ph</sup> could be the potential targets for osteosarcoma diagnosis and treatment.HighlightsH2A<sup>T120ph</sup> is specifically promoted by Ras-PI3K pathway activation.H2A<sup>T120ph</sup> joins in the oncogenic effects of Ras-PI3K pathway on osteosarcoma.H2A<sup>T120ph</sup> regulates the transcription of Ras-PI3K-targeted genes.VRK1 takes part in the regulatory function of Ras-PI3K pathway on H2A<sup>T120ph</sup>.
Functional analysis suggests that these lncRNAs were related to the PI3K-Akt signaling pathway, the Wnt signaling pathway, and the G-protein coupled receptor signaling pathway, all of which have various, important roles in osteosarcoma development.
