Abstract:
Objective Breast cancer is one of the deadliest malignancies in the world. ebracteolatain A (EA) is a kind of acetylphloroglucinol extracted from ebracteolatain. To explore the specific mechanism of EA inhibiting the proliferation of breast cancer cell MCF-7, so as to provide a new approach for the clinical treatment of breast cancer. Methods EA with different concentrations were added to breast cancer cell MCF-7 to detect changes in PKD1 protein expression. The plasmid with overexpressed PKD1 was constructed and transfected into cells, and the mRNA and protein expression levels of PKD1 were detected by real-time fluorescence quantitative PCR and Western Blot assay. CCK-8 assay was used to detect changes in cell proliferation capacity. Western Blot assay was used to detect the expression level of PKD1 and its related signaling pathways. Results EA inhibited the expression of PKD1 protein in breast cancer cells with a dose-dependent manner (P< 0.05). When transfected with the overexpressed plasmid, PKD1 was significantly increased in mRNA and protein levels (P<0.001). At the same time, PKD1 overexpression significantly reversed inhibition of EA on MCF-7 proliferation (P<0.001). It was confirmed by signaling pathway analysis that EA might affect the proliferation ability of breast cancer cells by inhibiting PKD1-mediated MEK/ERK and PI3K/AKT signaling activity (P<0.05). Conclusion EA could inhibit the proliferation of breast cancer cells by regulating PKD1-mediated MEK/ERK and PI3K/AKT signaling pathways.
