title: A new hypothesis for how sex steroid hormones regulate bone mass.
abstract: It has been proposed - but remains controversial - that estrogen's effects on various tissues may be mediated by different cell signaling pathways. Researchers have identified a synthetic ligand that activates only a subset of these pathways, suggesting that bypass of the traditional estrogen pathway can prevent bone loss without associated side effects on reproductive organs.
