In order to investigate the anti-proliferative effects of triptolide (TP) on 4T1 mice breast cancer cell line in vitro and in mouse model, as well as the possible mechanisms, we detected the effect of TP on cell proliferation by MTT assay or Crystal Violet Staining in our research. Flowcytometry combined with FITC-Annexin V/PI staining were used for detecting TP induced 4T1 cell apoptosis. The protein expression of ERalpha, p-ERalpha, ERbeta, p-ERbeta, ERK, p-ERK, p38, p-p38, SAPK/JNK, and p-SAPK/JNK was tested by western blotting. We also compare TP with chemotherapy drug doxorubicin in 4T1 tumor bearing BLAB/c mice model, the Xenogen bioluminescence imaging, H&E, and IHC result indicated that TP exhibits an anticancer proliferation activity. As a result, TP in 100, 10, 1, 0.1 micromol x L(-1), all inhibited the proliferation of 4T1 cells by MTT assay and Crystal Violet Staining. TP which concentrations is 10, 1, 0.1 micromol x L(-1) could induce the apoptosis of 4T1 cells and reduce the cell proliferation. TP in 200 microg x kg(-1) could inhibit the tumor growth in vivo. The anticancer proliferation of TP was involved in its effect on reducing expression of ERalpha, p-ERalpha, ERbeta, and p-ERbeta, but nothing to do with the activation of MAPK signaling pathway.

Crystal Violet (CV), a triphenylmethane dye, has been extensively used in human and veterinary medicine as a biological stain, as a textile dye in textile processing industries and also used to provide a deep violet color to paints and printing ink. CV is also used as a mutagenic and bacteriostatic agent in medical solutions and antimicrobial agent to prevent the fungal growth in poultry feed. Inspite of its many uses, CV has been reported as a recalcitrant dye molecule that persists in environment for a long period and pose toxic effects in environment. It acts as a mitotic poison, potent carcinogen and a potent clastogene promoting tumor growth in some species of fish. Thus, CV is regarded as a biohazard substance. Although, there are several physico-chemical methods such as adsorption, coagulation and ion-pair extraction reported for the removal of CV, but these methods are insufficient for the complete removal of CV from industrial wastewaters and also produce large quantity of sludge containing secondary pollutants. However, biological methods are regarded as cost-effective and eco-friendly for the treatment of industrial wastewaters, but these methods also have certain limitations. Therefore, there is an urgent need to develop such eco-friendly and cost-effective biological treatment methods, which can effectively remove the dye from industrial wastewaters for the safety of environment, as well as human and animal health.
