Abstract:
Research has indicated that Herba Patriniae can suppress the growth of Several kinds of tumor cells in vitro and in vivo, thus displaying favorable antitumor activity. However, research regarding the effect of saponins of Patrinia villosa against CRC cell has not been reported. In the current study, We have revealed that the effects of saponins of patrinia villosa on colorectal cancer (CRC) cell invasion and epithelial-mesenchymal transition (EMT) as well as its underlying mechanism.The CRC EMT model was induced through repeated TGF-β1 stimulations on human CRC cell line SW480. Effects of saponins of patrinia villosa at various concentrations on CRC SW480 cell and EMT model cell proliferation were detected using MTT method, so as to select the optimal action concentration. Meanwhile, effects on SW480 cell and EMT model cell invasion were determined through Scratch assay and Transwell assay. Moreover, changes in expression of EMT-related proteins E-cadherin, N-cadherin and NF-ΚBp65 in each group were detected through Western blotting.Saponins of patrinia villosa at various concentrations could markedly inhibit the proliferation rate of CRC cell in an obvious concentration-dependent manner. Meanwhile, saponins of patrinia villosa at various concentrations could also remarkably suppress migration of cell developing EMT. In addition, the protein expression of E-cadherin and N-cadherin was down-regulated with the increase in saponins of patrinia villosa concentration, while that of NF-KBp65 was notably down-regulated.Saponins of patrinia villosa can act against tumor invasion and metastasis through inhibiting EMT in human CRC cell line, which may be achieved through down-regulating the NF-κB signaling pathway.
