Effect of picroside Ⅱ on the malignant progression of non-small cell lung cancer
To investigate the effect and mechanism of picroside Ⅱ on the malignant progression of non-small cell lung cancer (NSCLC).
METHODS
2
A549 cells were divided into the control group, picroside Ⅱ low-, medium- and high-concentration groups, K6PC-5 [sphingosine kinase 1 (SPHK1) activator] group, and picroside Ⅱ high-dose+K6PC-5 group. Cell proliferation, migration and invasion were detected. Besides, the expression of proliferating cell nuclear antigen (PCNA), matrix metalloproteinase-2 (MMP-2), MMP-9, SPHK1, sphingosine-1-phosphate receptor 3 (S1PR3) and extracellular signal-regulated kinase 1/2 (ERK1/2) protein in the cells were also observed. BALB/c nude mice were subcutaneously inoculated with A549 cell suspension to establish NSCLC xenograft models. Then they were assigned to the nude mouse-control group, nude mouse-picroside Ⅱ low-, medium- and high-dose groups, nude mouse-K6PC-5 group, and nude mouse-picroside Ⅱ high-dose+K6PC-5 group (with 5 mice in each group) to investigate the effect of picroside Ⅱ on their tumor mass and volume.
RESULTS
2
Compared with the control group, the OD
450
values, EdU-positive cell rates, scratch healing rates, cell invasion number, and the relative expression levels of PCNA, MMP-2, MMP-9, SPHK1, S1PR3 and ERK1/2 protein in the low-, medium- and high-concentration groups of picroside Ⅱ were significantly decreased. Compared with the nude mouse-control group, the tumor mass and volume in the nude mouse-low-, medium- and high-dose groups of picroside Ⅱ were significantly decreased or shrunk. The changes of above indicators were concentration/dose-dependent (
P
<0.05). The changing trend of the corresponding indicators in the K6PC-5 group and the nude mouse-K6PC-5 group was opposite (
P
<0.05). Compared with the picroside Ⅱ high-concentration group or the nude mice-picroside Ⅱ high-dose group, the above quantitative indicators in the picroside Ⅱ high-concentration+K6PC-5 group cells and the nude mouse-picroside Ⅱ high-dose+K6PC-5 group nude mice were significantly increased or enlarged (
P
<0.05).
CONCLUSIONS
2
Picroside Ⅱ may inhibit the malignant progression of NSCLC by inhibiting SPHK1/sphingosine-1-phosphate/S1PR3 signaling pathway.
