Introduction: Silibinin, a polyphenolic flavonoid isolated from the milk thistle plant (Silybummarianum), has various applications in cancer therapy. This investigation aimed to examine the effects of silibinin on proliferation and chemokine receptor expression on MDA-MB-231 cells, a highly metastatic human breast cancer cell line.Methods: The cytotoxic effect of silibinin on MDA-MB-231 cells was determined by micro-culture tetrazolium test (MTT) assay. In addition, the expression of chemokine receptors CXCR3, CCR5 and CCR7 genes in response to silibinin was evaluated by Real-Time PCR.Results: Data analysis from MTT assay showed that silibinin had dose-dependent and time-dependent inhibitory effects on MDA-MB-231 cell line. Moreover, Real-Time PCR analysis showed that silibinin not only had no inhibitory effects on CXCR3, CCR5 and CCR7 gene expressions, but also could increase significantly the expression of these genes in a dose and time-dependent manner.Conclusion: These results revealed for the first time the increased possibility of CXCR3, CCR5 and CCR7 genes expression in response to silibinin in human breast cancer cells.Bangladesh Journal of Medical Science Vol.14(2) 2015 p.190-195

Three alkaloids (named rutaecarpine (1), evodiamine (2), schinifoline (3) and one phenylpropanoid, integrifoliodiol (4)) have been isolated from the EtOAc extract of the fruits of Tetradium ruticarpum (A. Juss.) T. G. Hartley collected in Lang Son province. Their structures have been identified by using 1D and 2D NMR spectroscopies. All four compounds were tested for their cytotoxicity against the human breast cancer cell line (MCF-7) and tamoxifen-resistant breast cancer cell line (MCF\TAMR). The results showed that rutaecarpine (1) inhibited the growth of MCF7 and MCF\TAMR with its IC50 values of 41.2 and 64.6 µM, respectively. In addition, compounds 1, 2, and 4 showed moderate activity toward MCF-7 cell line.
