RESUMO

The study investigated the effect of Compound Shougong Powder(CSGP) on the biological functions of triple-negative breast cancer(TNBC) cells and whether its mechanism of action was related to the epithelial-mesenchymal transition(EMT) signaling pathway. TNBC cells(MDA-MB-231 and BT-549) were treated with different concentrations of CSGP-containing serum. MTS assay was used to detect the effect of CSGP on the proliferation of TNBC cells. The EdU staining was used to detect the effect of CSGP on the proliferation of TNBC cells. Flow cytometry was used to examine the impact of CSGP on apoptosis of TNBC cells. Wound-healing and Transwell assays were used to evaluate the effects of different concentrations of CSGP on the migration and invasion capabilities of TNBC cells. RNA sequencing technology was utilized to elucidate its mechanism. Subsequently, qRT-PCR was performed to measure the mRNA expression levels of E-cadherin, N-cadherin, Slug, Snail, Vimentin, Twist, Zinc finger E-box-Binding homeobox 1(Zeb1), and Zinc finger E-box-Binding homeobox 2(Zeb2). Western blot was used to assess the protein expression levels of Slug, Vimentin, and E-cadherin. After intervention with CSGP, the proliferation of MDA-MB-231 and BT-549 cells significantly decreased, while the apoptosis rate markedly increased. The expression levels of the epithelial marker protein E-cadherin significantly increased, while the expression levels of the EMT-related transcription factors Slug and Vimentin showed a decrease. In conclusion, CSGP inhibits the EMT, thereby suppressing the malignant progression of TNBC.
