Abstract: Objective To investigate the effects of Decursin(DE)on the proliferation and migration of colorectal cancer cells and the underlying mechanism. Methods Third-generation SW480 and HCoEpiC cells were selected for the experiment,and the expression of miR-17-5p RNA in the two cell lines was detected via qRT-PCR.The proliferation of SW480 cells was detected via the CCK-8 method at different DE concentrations(0,10,30,60 and 100 μmol/L),and the appropriate concentration of DE was selected.qRT-PCR was used to detect the transfection efficiency of miR-17-5p in SW480 cells.The proliferation of the transfected cells was detected via CCK-8 method,and the number of migrating cells was detected via Transwell experiment.The expression of miR-17-5p was detected via qRT-PCR,the cell proliferation activity was detected via the CCK-8 method,the number of migrating cells was detected via Transwell experiment,and the levels of PIK3R1,p-PI3K,PI3K and p-Akt were detected via Western blotting.The dual-luciferase reporter assay was used to detect the targeting effect of miR-17-5p on PI3K. Results The expression level of miR-17-5p RNA in W480 cells was greater than that in HCoEpiC cells(P<0.05).The proliferation of SW480 cells decreased with increasing DE concentration in a concentration-dependent manner(P<0.05).For the subsequent experiments,60 μmol/L DE was selected.The miR-17-5p mimic/inhibitor significantly increased/decreased the expression of miR-17-5p,cell proliferation activity and the number of migrating cells(P<0.05).After treatment with DE,the expression of miR-17-5p,cell proliferation activity,cell migration,and p-PI3K and p-Akt proteins decreased(P<0.05),whereas the expression of the PIK3R1 protein increased(P<0.05);however,the expression of the PI3K and Akt proteins did not change significantly.When miR-17-5p and Wt-PIK3R1 were co-transfected,the relative luciferase activity decreased/increased with increasing/decreasing miR-17-5p expression(P<0.05).When miR-17-5p and Mut-Wt-PIK3R1 were co-transfected,the relative activity of luciferase did not change significantly(P> 0.05). Conclusion Decursin can inhibit the proliferation and migration of colorectal cancer cells,which may inhibit the PI3K/Akt pathway by downregulating miR-17-5p and promoting the expression of PIK3R1.
