- Abstract: Aim To explore the mechanism of Yanghe decoction-containing serum on the migration and inva-sion of MCF-7 breast cancer cells in a co-culture sys-tem with M2 tumor-associated macrophages(TAMs)based on the paracrine epidermal growth factor(EGF)/epidermal growth factor receptor(EGFR)sig-naling pathway.Methods The M2-type TAMs model was induced from THP-1 monocytic cell line through in vitro treatment with phorbol 12-myristate 13-acetate(PMA)and recombinant human macrophage colony-stimulating factor(M-CSF).The MCF-7 cells were co-cultured with M2-type TAMs using a Transwell non-contact co-culture system to evaluate their effects on migration and invasion.Subsequently,the cells were intervened with serum containing Yanghe decoction,and the proliferation of MCF-7 cells was detected using the CCK-8 assay,while their lateral migration ability was assessed through scratch assays.The invasion and vertical migration abilities of the cells were evaluated separately using Transwell assays,and the concentra-tion of EGF was measured using ELISA.Finally,the expression of EGFR,MCP-1,and MMP9 proteins was detected using Western blot.Results Compared to the control group,Yanghe decoction-containing serum in-hibited the proliferation of MCF-7 cells before and after co-culture.The serum reduced the scratch healing a-bility before and after co-culture and decreased their migration and invasion abilities.Additionally,Yanghe decoction-containing serum reduced the levels of EGF before and after co-culture and decreased the expres-sion of EGFR,MCP-1,and MMP9 proteins before and after+co-culture.Conclusion Yanghe decoction-containing serum can inhibit the migration and invasion of breast cancer MCF-7 cells before and after co-cul-ture with M2 TAMs.This effect may be related to the inhibition of the EGF-EGFR signaling pathway.
