Abstract:
ObjectiveTo investigate the effect of Chaihu Guizhitang on triple-negative breast cancer （TNBC） cells based on hypoxia-inducible factor-1α （HIF-1α）/vascular endothelial growth factor A （VEGFA） signaling pathway. MethodTNBC xenograft model was established and the cells were randomized into model group， capecitabine group （0.2 mg·kg-1）， Chaihu Guizhitang low-dose group， medium-dose group， and high-dose group （10.62， 21.23， 42.46 g·kg-1）， with 10 mice in each group. After 21 days of medication， the content of tumor necrosis factor-α （TNF-α） in serum was detected by enzyme-linked immunosorbent assay （ELISA）. The expression of HIF-1α mRNA was detected by real-time fluorogenic quantitative polymerase chain reaction （real-time PCR）. Immunohistochemistry （IHC） was employed to detect the expression of HIF-1α， TNF-α， and VEGFA in tumor tissues， and CD34 staining to examine the angiogenesis in tumor tissues. Microvessel density （MVD） was calculated， and the protein expression of HIF-1α， VEGFA， and epidermal growth factor receptor （EGFR） in tumor tissues was measured by Western blot. ResultCompared with the model group， the rest four groups showed low levels of TNF-α （P<0.01）， HIF-1α mRNA （P<0.01）， expression of HIF-1α， TNF-α， VEGFA， and CD34 in cells， and MVD （P<0.05， P<0.01）， and low protein levels of HIF-1α， VEGFA， and EGFR （P<0.01）. Compared with capecitabine group， medium-dose and high-dose Chaihu Guizhitang decreased the level of TNF-α （P<0.01）， HIF-1α mRNA （P<0.01）， expression of HIF-1α， TNF-α， and VEGFA in cells （P<0.01）， CD34 expression， MVD， and protein levels of HIF-1α， VEGFA， and EGFR （P<0.01）. ConclusionChaihu Guizhitang may inhibit the angiogenesis in TNBC cells by regulating the expression of HIF-1α/VEGFA signaling pathway， thus exerting anti-tumor effect.
