Research Progress on G2/M Arrest in Breast Cancer Cells by Active Compounds of Traditional Chinese Medicine / 中国实验方剂学杂志

ABSTRACT

The global incidence of breast cancer has increased year by year. Breast cancer has the highest mortality rate in female patients with malignant tumors. Traditional Chinese medicine（TCM） has made great contribution to health of human being， improving the overall curative effect， reducing the patients' pain， improving the quality of life and alleviating adverse reactions in patients. TCM and its active compounds can inhibit the proliferation of breast cancer cells by inducing cell cycle arrest， invasion， metastasis and reversing multidrug resistance. The effect of the compounds in TCM is obvious on inducing the arrest of the breast cancer cells cycle. It′s a novel method to fight against breast cancer by influencing the progress of the breast cancer cell cycle and inducing the cell cycle arrest in breast cancer cells. Lots of studies have shown that the G2/M phase checkpoint which transition from gap-phase （G2 phase） to mitotic phase （M phase） in the cell cycle is the key point for cell survival or death. Many antitumor drugs can inhibit the proliferation of tumor cells through the cell cycle arrest. We summarized the domestic and foreign literatures in recent years， and comprehensively explained the research progress on the related regulatory molecules in G2/M arrest. In addition， we summarized and sorted out the researches on the methods and ways of alkaloids， polysaccharides， terpenes， flavonoids， saponins and other active compounds of TCM in inducing the G2/M arrest of human breast cancer cells. By summarizing the active compounds of various Chinese medicines in inducing G2/M arrest of breast cancer cells， and reviewing the research progress on mechanism of active TCM compounds for inhibiting the proliferation of breast cancer cells， we will， in this paper， investigate the mechanism of active TCM compounds for inhibiting the proliferation of breast cancer cells through inducing G2/M arrest of human breast cancer cells， so as to provide a scientific basis for in-depth research on the anti-breast cancer mechanism of the active compounds in TCM.
