WebBreast cancer is the most frequently diagnosed cancer in women with a high incidence and mortality worldwide. Nearly 70% of breast carcinomas express steroid hormone receptors and therefore patients can be treated with endocrine therapy. The treatment is principally targeted to block the estrogen receptor (ER) or estrogen synthesis ( 1 ). WebThe addition of exogenous substrates can be used to block cells in certain phases of the cell cycle and frequently target cell cycle checkpoints. These techniques can be carried out in vitro and do not require removal from the culture environment. The most common type of chemical blockade is arrest-and-release, which involves treatment of a ...
