Cancer&Entry Information
Cancer Name | osteosarcoma |
ICD-0-3 | NA |
Methods | Western blot analysis, qRT-PCR, RIP, Luciferase reporter assay |
Sample | fresh bone marrows,osteosarcoma cell lines (MNNG/HOS, Saos-2, and MG-63) |
Expression Pattern | up-regulated |
Function Description | The co-culturing of BMSC-derived exosomes and osteosarcoma cells (Saos-2, MG-63, and MNNG/HOS cell lines) significantly raised PVT1 expression of osteosarcoma cells. The direct binding between PVT1 and the oncogenic protein ERG was confirmed using RNA immunoprecipitation and RNA pull-down assays, and the transported PVT1 promotes osteosarcoma cell proliferation and migration via inhibiting degradation and ubiquitination of ERG. PVT1 also increased ERG expression through sponging miR-183-5p. In summary, our findings indicated that BMSC-derived exosomes encapsulate PVTl and transport it into osteosarcoma cells, and the transported PVT1 promotes tumor growth and metastasis by inhibiting ubiquitination and promoting expression of ERG in osteosarcoma cells. |
