Abstract:
Objective To investigate the effects of sauchinone(Sch)on the growth and immune escape of liver cancer cells by regulating the Krüppel like factor 5(KLF5)-erythropoietin-producing hepatocellular receptor A2(EphA2)pathway.Methods Huh-7 cells were grouped into liver cancer group,Sch low,medium,and high-dose groups(Sch-L group,Sch-M group,Sch-H group),Sch-H+KLF5 activator negative control group(OE-NC),and Sch-H+KLF5 activator(OE-KLF5)group.5-bromo-2-deoxyuracil(EdU)staining,CCK-8,scratch assay,and Transwll were used to detect the proliferation,migration,and invasion of Huh-7 cells,respectively.Western blot was applied to detect proliferative cell nuclear antigen(PCNA),migration invasion enhancer(MIEN1),matrix metalloproteinase-2(MMP-2),programmed death receptor ligand 1(PD-L1),KLF5,and EphA2 proteins in Huh-7 cells.The Huh-7 cells in above 6 groups were co cultured with activated CD8+T cells in a 96 well plate and named as liver cancer co culture group,Sch-L co culture group,Sch-M co culture group,Sch-H co culture group,Sch-H+OE-NC co culture group,and Sch-H+OE-KLF5 co culture group.The killing rate of CD8+T cells in the co culture system and the levels of interferon-γ(IFN-γ),interleukin-4(IL-4),and tumor necrosis factor-α(TNF-α)in the supernatant were detected.Results Compared with the liver cancer group,the EdU positive rate,OD450 value,cell invasion number,and PCNA,MIEN1,MMP-2,PD-L1,KLF5,and EphA2 proteins in the Sch-L,Sch-M,and Sch-H groups reduced,the migration distance shorten(P<0.05).Compared with the Sch-H group and Sch-H+OE-NC group,the EdU positive rate,OD450 value,cell invasion number,and PCNA,MIEN1,MMP-2,PD-L1,KLF5,and EphA2 proteins in the Sch-H+OE-KLF5 group increased,the migration distance prolonged(P<0.05).Compared with the liver cancer co culture group,the killing rate of CD8+T cells on Huh-7 cells and the levels of IFN-γ,TNF-α,and IL-4 in the supernatant in the Sch-L co culture group,Sch-M co culture group,and Sch-H co culture group increased(P<0.05).Compared with the Sch-H co culture group and the Sch-H+OE-NC co culture group,the killing rate of CD8+T cells on Huh-7 cells and the levels of IFN-γ,TNF-α,and IL-4 in the supernatant in the Sch-H+OE-KLF5 co culture group decreased(P<0.05).Conclusion Sch may inhibit growth and immune escape of liver cancer cells by inhibiting the KLF5-EphA2 pathway.
