Abstract

Polysaccharides extracted from medicinal plants possess multiple functions. However, the inhibitory capacity of polysaccharides on the metastasis of breast cancer remains unclear. In the present study, we investigated the inhibitory activity of Aconitum coreanum polysaccharide (ACP1) and its sulphated derivative ACP1-s on migratory behaviour of human breast cancer cells MDA-MB-435s and evaluated the underlying molecular mechanism. The data from Transwell assay indicated that ACP1 and ACP1-s caused a significant inhibition of MDA-MB-435s cell migration in vitro. ACP1 and ACP1-s significantly impaired MDA-MB-435s cell migratory behaviour, and the accumulated distance and average velocity of ACP1- and ACP1-s-treated cells were reduced markedly. We also found ACP1 and ACP1-s treatment could affect dynamic remodeling of actin cytoskeleton, and suppress phosphorylation and activation of signalling molecules, attributing to anti-metastatic role of ACP1 and ACP1-s. These findings reveal a novel therapeutic potential of A. coreanum polysaccharide and its sulphated derivative for breast cancer metastasis.
