Abstract:

BACKGROUND: Adriamycin can inhibit the proliferation of osteosarcoma cells, but the effects of adriamycin alone or combined with everolimus on osteosarcoma stem cells are not well documented.
OBJECTIVE: To explore the effects of adriamycin combined with everolimus, a mTOR inhibitor, on the proliferation and invasion of osteosarcoma stem cells.
METHODS: CD133+ osteosarcoma stem cells were separated from MG63 cells by flow cytometer. We first used MTT method to detect the proliferation of osteosarcoma stem cells treated with adriamycin at the concentrations of 0, 0.1, 0.2, 0.4 mg/L. Next, we chose an appropriate concentration of adriamycin (0.2 mg/L) combined with 20 μmol/L everolimus to act on CD133+ osteosarcoma stem cells. MTT and Transwell method were then used to detect the cell proliferation and invasion after intervention with 0.2 mg/L adriamycin alone or combined use of adriamycin (0.2 mg/L) and everolimus (20 μmol/L), respectively. Meanwhile, the expression levels of proliferating cell nuclear antigen and matrix metalloproteinase 9 in the osteosarcoma stem cells were detected by western blot.
RESULTS AND CONCLUSION: MTT results showed that adriamycin and especially adriamycin combined with everolimus could inhibit the proliferation of CD133+ osteosarcoma stem cells. Transwell assay results showed that adriamycin combined with everolimus could inhibit the invasion of osteosarcoma stem cells. Western blot results showed that adriamycin combined with everolimus significantly decreased the levels of proliferating cell nuclear antigen and matrix metalloproteinase 9 compared with the control group. These findings suggest that everolimus can enhance the ability of adriamycin against the proliferation and invasion of osteosarcoma stem cells.
