In this episode, Will sat down with Dr. Aaron Ciechanover, biologist and Distinguished Research Professor in the Rappaport Faculty of Medicine at the Technion, Israel Institute of Technology. Dr. Ciechanover is renowned for his work in studying the method that cells use to degrade and recycle proteins. While in the laboratory of Avram Hershko, they discovered that small proteins, called ubiquitin, were attached in chains to targeted proteins, marking them for degradation by a proteasome. This system is highly regulated and was subsequently found to be a factor in many diseases and areas of biology, so much that in 2004, Dr. Ciechanover was awarded the Nobel Prize in Chemistry while on faculty at Washington University. Enjoy!

Today, I sat down with Dr. Brian Kobilka, Professor in the Department of Molecular and Cellular Physiology at Stanford University School of Medicine. Dr. Kobilka is an expert on a class of receptors called G protein-coupled receports, or GPCRs, that are essential in a majority of biological processes including light, flavor, and odor perception and in the activity of adrenalin, dopamine, and serotonin. In fact, currently approximately half of all pharmaceuticals on the market target GPCRs. In the mid 1980s Dr. Kobilka and his colleagues from the Robert Lefkowitz lab were the first to clone the gene for an important GPCR called the beta2-adrenergic receptor, and later he and his collaborators were the first to determine its molecular structure, which served as the basis for understanding all subsequent GPCRs and creating drugs to target them. This work proved to be revolutionary in many areas of science and medicine, such that in 2012, Kobilka was awarded the Nobel Prize in Chemistry for his contributions to understanding GPCRs. In this interview, we talk about these amazing findings and the recent advances in understanding this important class of receptors.

Prof. W.E. Moerner is the Harry S. Mosher Professor of Chemistry, Professor, by courtesy, of Applied Physics at Stanford University, and WashU alum! Professor Moerner is a physical chemist, a scientist that studies chemical processes using physics. In 1989, he and his postdoc developed a method that accomplished the first ever optical detection and spectroscopy of a single molecule, something that was previously thought to be impossible. Single molecule spectroscopy laid the groundwork for using fluorescence in individual molecules to study processes inside living cells. This technique, called super-resolved fluorescence microscopy, was revolutionary because it enabled scientists to attain high resolution images of the nanoworld that was previously invisible to us. For this work, Professor Moerner was jointly awarded the 2014 Nobel Prize in Chemistry, the highest honor for any scientist in the world. The Moerner Lab continues to develop single molecule microscopy by developing methods for 2D and 3D super resolution imaging of cells. Some of their current projects include measuring amyloid aggregation in neurons, studying protein localization patterns in bacteria, and quantifying dynamics of photosynthetic proteins.
Professor Moerner’s work has contributed to many areas of physics, chemistry, and biology, so it is important to understand exactly how the study of single molecules is possible. Not only is he a brilliant scientist, but he is a fantastic communicator of his work, and we learned a lot from this interview so we hope you enjoy this episode.

This week on Master Minds, we talked to Dr. Erik Herzog, Viktor Hamburger Distinguished Professor in Arts & Sciences and Professor of Biology at Washington University. Dr. Herzog is a chronobiologist - a scientist that studies how organisms create biological rhythms to help adapt to their environment. He is an expert on how the brain regulates circadian rhythms, which are physiological processes that follow a roughly 24-hour cycle. Circadian rhythms are relevant to nearly all other aspects of biology, including fluctuations in body temperature, hormone levels, and sleep as well as in the context of disease. Throughout the interview, Dr. Herzog explains the molecular mechanisms behind circadian rhythms and how a structure in the brain called the suprachiasmatic nucleus (SCN) serves as the master clock for all cells in the body. He also talks about the ways in which circadian rhythms can be used to optimize sleep and performance.
