Objective:To investigate the role and significance of histone acetylation in proliferation of breast cancer cell line MCF-7 induced by estrogen. Methods:Human breast cancer MCF-7 cells were used as the research object. Effect of 17β-estradiol(17β-E2) on proliferation of MCF-7 cells was investigated with CCK-8 assay and the optimal concentration of 17β-E2in the following experiment was determined according to the proliferation rate. Effect of Garcinol on proliferation of MCF-7 cells by 17β-E2was investigated...
