Tracking how steroid hormone receptor proteins evolved

When thinking about the evolution of female and male, consider that the first steroid receptor proteins, which emerged about 550 million years ago, were responsive to estrogen. The ancestor of other steroid hormone receptors, responsive to hormones such as testosterone, progesterone and cortisol, emerged many millions of years later. Biochemist Eric Ortlund and colleagues have a new paper in Structure that reconstructs how interactions of steroid receptor proteins evolved over time. This is a complex Read more

DBS for drug-resistant epilepsy

Space considerations in print forced us to slim down the feature on deep brain stimulation for drug resistant epilepsy, which appears in the Spring 2015 issue of Emory Medicine. While I encourage you to please read our story profiling playwright Paula Moreland, here are some take-away points:

*Surgery is a viable option for many patients with drug-resistant epilepsy, but not all of them, because the regions of the brain where the seizures start can have important functions. (Look for an upcoming post describing a patient I met for whom the surgical option was helpful.)

*Deep brain stimulation can reduce seizure frequency and improve quality of life for patients with drug-resistant epilepsy.

*In the large clinical trials on deep brain stimulation for epilepsy that have been run so far (SANTE and RNS), most participants do not see their seizures eliminated. Ms. Moreland is an exception.  Read more
