Midazolam inhibits proliferation, migration and induces apoptosis of osteosarcoma cells
To investigate the effect of midazolam on the proliferation, apoptosis and migration of osteosarcoma cells and its mechanism.
Methods
2
The tumor tissue and adjacent non-tumor bone tissue samples of 38 patients with osteosarcoma in our hospital were collected. Human osteosarcoma cell lines (MG63, U2OS, SAOS2, HOS, 143B) and normal osteoblast cell lines (hFOB1.19) were cultured in vitro. qRT-PCR was used to detect the expression of circNOL10 in tissues and cells. U2OS cells were divided into the control group, the low midazolam group, the middle midazolam group, the high midazolam group, the pcDNA-circNOL10 group, the pcDNA group, the midazolam+si-NC group, and the midazolam+si-circNOL10 group. Flow cytometry, Transwell, CCK-8 and qRT-PCR were used to detect the apoptosis rate, migration number, proliferation activity and circNOL10 expression level of U2OS cells.
Results
2
Compared with normal tissues and cells, the expression of circNOL10 in osteosarcoma tissues and cells was significantly decreased (
P
<
0.05). Compared with the control group, the apoptosis rate, inhibition rate, E-cadherin protein level, and circNOL10 expression level of U2OS cells in the low midazolam group, the middle midazolam group, and the high midazolam group were significantly increased (
P
<
0.05), while the migration number and N-cadherin protein level were significantly reduced (
P
<
0.05). Compared with the pcDNA group, the apoptosis rate, inhibition rate and E-cadherin protein level of U2OS cells in the pcDNA-circNOL10 group were significantly increased (
P
<
0.05), while the migration number and N-cadherin protein level were significantly reduced (
P
<
0.05). Compared with the midazolam+si-NC group, the apoptosis rate, inhibition rate and E-cadherin protein level of U2OS cells in the midazolam+si-circNOL10 group were significantly reduced (
P
<
0.05), while the migration number and N-cadherin protein level were significantly increased (
P
<
0.05).
Conclusion
2
Midazolam induces apoptosis of osteosarcoma cells, and inhibits its proliferation and migration by up-regulating the expression of circNOL10.
