Mechanisms of estrogen action

WebEstrogen, one of several sex steroid hormones, mediates its actions through the estrogen receptor. The estrogen receptor (ER) has two subtypes, ER alpha and ER beta, each of which predominates in specific tissues and organs. Cofactor proteins interact with the ER to maximize ligand-dependent transactivation of target-gene promoters. WebIn this research project, we're investigating mechanisms of estrogen action on bone by engaging in a series of studies that focus on better defining underlying mechanisms by which estrogen regulates bone turnover. As part of this project, our research team is deleting estrogen receptor alpha, estrogen receptor beta, or both, in a cell- and time ...
