Ursolic acid induces apoptosis by suppressing the expression of FoxM1 in MCF-7 human breast cancer cells.

Ursolic acid (UA), a naturally occurring pentacyclic triterpene, is a potent in vitro anticancer agent, acting through control of growth, apoptosis, and differentiation. As the anticancer effect and the mechanism of action of ursolic acid on human breast cancer cells has not been extensively studied, we performed an evaluation of the effects of UA on apoptosis in MCF-7 cells. UA was found to inhibit the proliferation of MCF-7 cells in a concentration and time-dependent manner.

Effects of SMYD3 over-expression on cell cycle acceleration and cell proliferation in MDA-MB-231 human breast cancer cells.

SET and MYND domain-containing protein 3 (SMYD3) is a histone methyltransferase that plays an important role in transcriptional regulation in human carcinogenesis. It can specifically methylate histone H3 at lysine 4 and activate the transcription of a set of downstream genes, including several oncogenes (e.g.
