AimThis study sought to explore the exact mechanism of Matrine inhibited migration and invasion of human pancreatic cancer cells.MethodsHPAC or Capan-1 cells were cultured in completed RPMI-1640 medium, contained with 50 μg/ml Matrine or 0.05 μg/ml docetaxel, respectively. Cell viability was evaluated by spectrophotometric analysis using MTT assay. Wound healing assay and transwell approach were used to detect the effects of Matrine on HPAC cell migration and invasion. Western Blot and RT-PCR were performed to detect the expressions of MT1-MMP, Wnt and β-Catenin. CHIP assay was used to detect whether the MT1-MMP transcription activity correlated with Wnt signaling pathway.ResultsMTT results indicated that cell proliferration was inhibited by Matrine at a range of concentrations, especially at high dose. We further found that Matrine treatment significantly induced cell migration and invasion decreased. Interestingly, the expression of MT1-MMP decreased evidently upon Matrine treatment, paralleled with the expressions of Wnt and β-Catenin detected by Western Blot and RT-PCR assay. Further analysis of MT1-MMP transcription activity revealed that Matrine reduced the expression of MT1-MMP mediated by Wnt signaling pathway.ConclusionMatrine play a vital role in inhibiting HPAC cellular migration and invasion through down-regulating the expression of MT1-MMP via Wnt signaling pathway.Electronic supplementary materialThe online version of this article (doi:10.1186/s12935-015-0210-4) contains supplementary material, which is available to authorized users.

genetic differentiation along with the whole sampling range. Also, distinct phylogeographic structures were detected among populations of C. hendersonii based on both of cpDNA and ITS variation. These findings shed new light on the importance of climatic oscillations during Quaternary and complex local topography as causes of intraspecific diversification and demographic changes within cold-tolerant herbs in the Tibetan Plateau biodiversity hotspot.
