Charles Darwin had a theory. A theory that people and animals could evolve by growing, changing and adapting to their conditions. Evolution, now widely known and accepted throughout the world of science, still has many unknown factors, and how certain things evolve is still being studied. How proteins evolve from having one function to multiple functions, and how RNA molecules evolve from being unimportant to having vital roles in cell regulation are a few of the things that scientists are still researching.

The W.M Keck Foundation recently awarded Eric Ortlund, PhD. of Emory University $1 million to support his research of how gene regulation changes and evolves. Ortlund's research focuses on studying the glucocorticoid receptor (a steroid hormone receptor) and how it evolves to have different functions without losing previous functions.

The glucocorticoid receptor is being studied because it has the ability to turn some genes on while turning others off, and can also bind DNA in different modes to accomplish these functions. Other receptor's related to the glucocorticoid receptor, like progesterone and mineralocorticoid, only have one ability - to activate.
Why does the glucocorticoid receptor have a second function that other related receptor's do not? How did this evolution occur? These are the types of questions that Ortlund and his Emory research team are working to answer. Through reconstructing and studying ancestral steroid receptor molecules that are no longer found in living organisms, the bioresearchers hope to understand how changes occurred.
“We will walk these ancient proteins and non-coding RNAs forward through evolutionary time to understand how DNA sequence changes drove changes in cell signaling,” Ortlund explained.
The glucocorticoid receptor is also a protein target for certain anti-inflammatory drugs and is a target of a decoy RNA molecule, Gas5, that has a role in certain cancers. Through further research of this receptor, the researchers will not only gain a better understanding how evolution occurs at a molecular level, but they will also be able to provide information that could help with the development of new anti-inflammatory and anti-cancer drugs.
