modulate estrogen effects in different tissues selectively
Selective Estrogen Receptor Modulators (SERMs) are a class of compounds that act on the estrogen receptor. They can either block or activate estrogen's effects in different tissues, depending on the specific SERM and the tissue type. For example, they might block estrogen's action in breast tissue to reduce the risk of breast cancer, while activating it in bone tissue to help maintain bone density.
