In recent years,many new microtubule-associated proteins are found or studied extensively in the treatment of breast cancer.End-binding protein 1 (EB1)has the promotional effects on cell proliferation and enhances the carcinogenesis of breast cancer,and also can affect the chemosensitivity of the treatment. MAP7 domain-containing protein 3 (Mdp3)expresses in breast epithelial cells and plays an important role on the growth and metastasis.Nucleolar and spindle-associated protein (NuSAP)gene is up-regulated in breast cancer and is considered as a biomarker for breast cancer.Tau expression level has a strong correlation with estrogen receptor (ER),progesterone receptor (PR)and human epidermal growth factor receptor-2 (HER-2), and it remains controversial in the results of the effect of paclitaxel chemotherapy and hormone treatment.

AIM: To study the effects of disulfiram/copper complex (DSF/Cu) on ultrastructures and mechan-ical properties of human breast cancer and normal breast epithelial cells by atomic force microscopy (AFM) based on the nanoscale resolution and piconewton force measurement level.METHODS: The change of cell cycle and apoptotic rate of MCF-7 cells and MCF-10A cells induced by DSF/Cu were compared by flow cytometry.The cell surface morphology, ultra-structure, height, width and roughness were detected by AFM.The effects of DSF/Cu on the hardness (Young’s modu-lus) of the 2 kinds of cells were determined by AFM with indentation technique.RESULTS: DSF/Cu significantly in-duced apoptosis of the MCF-7 cells in a dose-dependent manner, whereas had little effect on the MCF-10A cells.The cell cycle analysis showed that DSF/Cu induced G2 /M arrest in the MCF-7 cells, but led to G0 /G1 arrest in the MCF-10A cells.The AFM images showed that the MCF-7 cells shrank and showed smaller and smoother morphology, and the filopo-dia were retracted obviously, even some became into lamellipodia, or disappeared completely after treated with DSF/Cu at concentrations of 400 and 800 nmol/L.The quantitative analysis indicated that the MCF-7 cells showed smaller width and
larger height, and the root mean square roughness and average roughness were decreased significantly in a dose-dependent manner after treated with DSF/Cu at concentrations of 400 and 800 nmol/L.However, little effect in the MCF-10A cells was observed.The biomechanics test at a single cell level demonstrated that the Young’s modulus of the MCF-7 cells and MCF-10A cells were both increased, yet the proportion increased in the MCF-7 cells was much higher than that in the MCF-10A cells after treated with DSF/Cu at concentrations of 400 and 800 nmol/L.CONCLUSION: DSF/Cu has strong antitumor effect on breast cancer with high efficiency and low toxicity by changing the properties of the biomechanics specifically.
