Abstract

A cell is an organic whole containing biological macromolecules such as nucleic acid and protein. Human cells contain about 15,000 proteins, which play an important role in the development of cell life. This article aims to study the effect of phytoestrogens on the proliferation of breast cancer cells MCF-7. The estrogen-dependent MCF-7 cells described in this article are grown on average DMEM (containing calf serum 10) and connected to single cell culture. Five days before adding the test product, the cells were washed with PBS and converted into red-free phenol. High-sugar DMEM containing 5 parts of bovine embryo serum was cultured and treated with activated charcoal glucan glycosides. In the experiment, four dose groups of solvent control, estrogen control, anti-estrogens and two test substances were used for control, and the proliferation of MCF-7 cells was analyzed by integration method and flow cytometry. The experimental results in this article show that compared with the solvent control group, GS can significantly inhibit MCF-7 cell proliferation and cell DNA synthesis, and G/M can block the cell cycle and produce a similar inhibitory effect. 96mol/L zein treatment for 24 hours can significantly promote MCF-7 cell proliferation and cell DNA composition, promote cell cycle, and increase cell separation and proliferation index.
