PSMB1 and osteosarcoma: This paper mainly studied the significance of CNV-lncRNA in the prognosis of osteosarcoma by bioinformatics methods and firstly concluded that AC129492.1, PSMB1, and AC037459.4 could be used as prognostic markers of osteosarcoma, which may provide theoretical basis and reference value for the study and prognosis of osteosarcoma in the field of copy number and noncoding RNA.
