Effect of uroacitides on the expression of cyclin D1 of breast cancer cells / 解放军医学杂志

ABSTRACT

Objective To investigate the effect of CDA-Ⅱ on t he expression of cyclin D1 of breast cancer cells. Methods The br east carcinoma cell lines MCF-7 and MDA-MB-231 were cultured in vitro tog ether with CDA-Ⅱ, with retinoic acid as positive control, and the effect of CD A-Ⅱ on the growth curve as well as the expression of cyclin D1 of breast carci noma cell lines was observed. Results CDA-Ⅱ may reduce the gr owth of MCF-7 and MDA-MB-231, cripple their proliferative ability and inhibit the cyclin D1 expression of breast cancer cell lines. Conclusion CDA-Ⅱ may inhibit the growth and proliferation of MCF-7 and MDA-MB-231, reduce the expression of breast carcinoma cell cyclin D1, hence showed a good a pplied prospect for the treatment of breast carcinoma.
