Such fusion proteins are inactive in the absence of ligand, because they are complexed with a variety of intracellular polypeptides. Upon ligand binding, the receptor is released from its inhibitory complex and the fusion protein becomes functional. In the murine estrogen receptor (ER) fusion system, proteins are fused to the HBD of the ER. The system relies on the use of a mutant ER known as ERTAM. Compared to the wild-type HBD, ERTAM has 1000-fold lower affinity for estrogen, yet remains responsive to activation by the synthetic steroid 4hydroxytamoxifen (4-OHT). Because 4-OHT is expensive, animals can be treated with the cheaper precursor tamoxifen, which is converted into 4-OHT by a liver enzyme.

    Tamoxifen has rarely caused very serious (possibly fatal) strokes, blood clots in the lungs/legs, and cancer of the uterus. If you are taking tamoxifen to reduce the risk of breast cancer, or if your cancer is limited to the milk ducts (ductal carcinoma in situ-DCIS), then discuss the benefits and risks of taking this medication with your doctor. However, if you are taking tamoxifen to treat breast cancer, then the benefits of taking tamoxifen are greater than the risks of side effects. Get medical help right away if you develop symptoms of a stroke or blood clots in the lungs/legs, such as weakness on one side of the body, slurred speech, sudden vision changes, confusion, shortness of breath, chest pain, or calf pain/swelling. Tell your doctor right away if you develop symptoms of cancer of the uterus, such as unusual changes in your monthly period (e.g., amount or timing of bleeding), unusual vaginal discharge, or pain/pressure below your "belly button" (navel). Show More Tamoxifen is used to treat breast cancer. It is also used to reduce the chances of breast cancer in high-risk patients. This medication can block the growth of breast cancer. We investigated the kinetics of tamoxifen (tam) in immunodeficient mice and rats after oral treatment and compared drug and metabolite profile in nude rat serum and tissues after oral and subcutaneous (s.c.) routes of administration. The serum levels were compared to those observed in man. After oral dosing in mice, tam and the potent metabolite 4-hydroxytamoxifen (4-hydroxytam), were detectable in liver and lung tissue, but not in serum. The levels of 4-hydroxytam in these tissues were significantly higher than those of tam, a profile opposite to that observed in rat and man. In rats and man, the 4-hydroxytam/tam serum concentration ratios were 0.16 and 0.02, respectively. pellets yielded only trace amounts of the demethylated derivatives of tam in rats. Thus, the kinetics of tam observed in the present study suggest that the nude rat may represent a preferable animal model in studying the pharmacokinetics of tam and that, the oral route yielded higher serum and tissue levels of tam and metabolites than equivalent s.c.
