This Podcast features an interview with Zeynep Madak-Erdogan, Benita Katzenellenbogen, and John Katzenellenbogen, authors of a Research Article that appears in the 24 May 2016 issue of Science Signaling, about designer estrogens that have the therapeutic benefits of natural estrogens, but less cancer risk. In addition to controlling female reproduction and secondary sex characteristics, estrogen is also an important regulator of metabolism, the vasculature, and bone. Estrogen production decreases as women enter menopause, leading to changes in metabolism, a reduced ability to repair blood vessels, and decreased bone density. Although hormone replacement therapy can alleviate these symptoms, it can also promote the growth of uterine and breast cancers. Madak-Erdogan et al. engineered synthetic forms of estrogen that activate the cytosolic signaling pathways that are associated with the beneficial effects of this hormone without also activating the nuclear signaling events associated with cancer growth.
