Abstract:
:CXC motif chemokine ligand 10 (CXCL10) and its receptor CXC motif chemokine receptor 3 (CXCR3), play important roles in the motility of breast cancer cells. Alisma canaliculatum is a herb that has been used as a traditional medicine for thousands of years in Korea and China. Whether A. canaliculatum inhibits the motility of metastatic breast cancer cells is not clear yet. In this study, we show that A. canaliculatum ethanolic extract (ACE) prevented tumor necrosis factor-alpha (TNFα)-induced migration of MDA-MB-231 cells. ACE significantly attenuated TNFα-induced upregulation of CXCL10 and CXCR3 expression at the gene promoter level. Mechanistically, ACE inhibits TNFα-induced phosphorylation of inhibitor of κB (IκB) kinase (IKK), IκB and p65/RelA, leading to the suppression of nuclear translocation of p65/RelA nuclear factor kappa-B (NF-κB). Also, ACE inhibited NF-κB-dependent CXCR3 and CXCL10 promoter activities. These results suggest that ACE abrogates TNFα-induced migration of MDA-MB-231 breast cancer cells through down-regulation of IKK-NF-κB-dependent CXCR3 and CXCL10 expression. Our results suggest that ACE has potential as a herbal supplement for the inhibition of breast cancer metastasis.
