ABSTRACT OBJECTIVE To investigate the effect and mechanism of picroside Ⅱ on the malignant progression of non-small
cell lung cancer (NSCLC). METHODS 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 Compared with
the control group, the OD450 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
