Project Title: Investigation of a protein complex implicated in P14P synthesis in the brain

My current research concerns the mechanisms by which cells regulate the biosynthesis of phosphoinositides, a class of lipids found on the cytosolic face of numerous membranes within the cell. In particular, I am interested in studying the metabolic interconnectedness of different classes of lipids._x000D_

I was born and raised in Montreal, Canada in a family of artists. My parents are both classical musicians, and my younger sister is a budding actress; to this day I play classical piano as a hobby. I was drawn to chemistry in high school, and my interest in organic chemistry grew in my undergraduate years at MIT, where I received a B.S. in 2004. Midway through MIT, inspired by an advanced biochemistry class, I joined a young chemical biology lab. I continued in this area in my graduate years at UC Berkeley, in the laboratory of Carolyn Bertozzi, where my research concerned the development of chemical tools for imaging cell-surface glycans in living systems. After earning a Ph.D. in chemistry in 2009, I again switched direction, embarking on post-doctoral research in cell biology, under the supervision of Pietro De Camilli.

Project Title: Neural plasticity underlying social dominance behavior in cichlids

Intuitively, humans seem aware of the fact that visceral sensations are related to their emotional or stress perceptions of the world. English idioms such as the heart “leaping” reflect excitement, the heart “sinking” reflects despair, and “gut feelings” reflect intuition. This conscious awareness of the reactions of the viscera suggests a two-way relationship between perception of the body and reaction of the brain, but the biological underpinnings and relevant neural circuits are still understudied._x000D_

The zebrafish has the great advantage of external fertilization and optical accessibility during development, which I will utilize to study how sensory inputs from the body shape brain state and activity. I hope to understand the kinds of sensory information transmitted from the body to the brain, and the ways that this affects how the brain generates behaviors._x000D_

Gwendolyn M. Beacham, Ph.D. Jane Coffin Childs Fellow

Boston University

Project Title: Manipulating vascular endocytosis to direct blood and immune cell migration

The vascular system transports blood and immune cells throughout the body. Yet, how these cells selectively cross the endothelium and enter the appropriate cellular tissues is unclear. Dr. Gwendolyn Beacham will explore the fundamental mechanisms underlying this endothelial transmigration in Dr. Elliott Hagedorn’s and Dr. Christopher Chen’s labs at Boston University. Beacham predicts that endocytosis is important for this process and has identified candidate proteins by investigating blood stem cells. She will use zebrafish as a model system to validate her preliminary findings. Then, Beacham will use this understanding to engineer blood vessels with controllable endothelial transmigration in zebrafish and in human cell culture. This research may help improve the efficiencies of cancer therapies that rely on endothelial transmigration, such as bone marrow transplants and engineered CAR T-cells.

As a Ph.D. student in Dr. Gunther Hollopeter’s lab at Cornell University, Beacham investigated clathrin-mediated endocytosis. In particular, she discovered that endocytosis is inactivated via phosphorylation of the clathrin Adaptor Protein 2. These findings revealed a novel regulatory mechanism for endocytosis and set up Dr. Beacham to explore how endocytosis contributes to endothelial transmigration.

Project Title: The role of hopanoids in plant-microbe symbioses

A native of rural Pennsylvania, my interest in biology was sparked by a summer research program for high school students on ribosome biogenesis at Carnegie Mellon University. As an undergraduate, I studied biochemistry and philosophy at the University of Notre Dame, where I researched the molecular evolution of bacterial actin-like proteins with Dr. Holly Goodson. I continued my Westward migration to pursue a PhD at UCSF. In my thesis research with Dr. Dyche Mullins, I developed new tools for in vivo imaging of nuclear actin, which I used to discover a role for nuclear actin filaments in the DNA damage response.

As a postdoc I decided to jump across the branches of the tree of life, and I am currently working in the lab of Dr. Dianne Newman at Caltech to determine how the membrane composition of rhizobia, soil bacteria that engage in symbiotic nitrogen fixation in the roots of legume plants, affects their symbiotic fitness and recognition by plant hosts. I am particularly interested in the role of hopanoid lipids, which may be required for bacterial adaptations to environmental stress.

Project Title: Cell fate and intercellular signaling in planarian regenerative organizers

The growth and regeneration of adult tissues requires the establishment of local signals that regulate growth and differentiation. While signaling molecules regulating proliferation have been studied in a wide range of tissue and disease contexts, mechanisms linking tissue composition and cellular cooperativity to growth and regenerative potential are poorly understood. During development, signaling centers with a defined genetic signature ‚Äì organizers ‚Äì induce the proliferation, migration, and differentiation of neighboring cells and establish patterns critical for the formation of adult organ systems. However, it is unclear if comparable signaling centers regulate tumor development or regeneration. The planarian worm provides a unique opportunity to study the establishment and function of regenerative signaling centers in vivo due to its extraordinary ability to regenerate organ systems from tiny fragments in approximately one week.

As a postdoctoral fellow in the Sanch√©z laboratory at the Stowers Institute for Medical Research, I plan to use a combination of sequencing and quantitative imaging techniques to identify the minimal cell types and tissue structures required for complete regeneration and accurate scaling of planarian worms. This work is expected to reveal novel mechanisms regulating self-organization and growth in resource-limited adult tissues and may expand our ability to improve human regenerative capacity and treat human cancers that arise from aging tissues.

Project Title: Synergistic modulation of heritable transcriptional memory

Chemical modifications to DNA and histones are implicated in the establishment of heritable cell type-specific transcriptional networks. The emergence of molecular epigenetic editors creates new opportunities to mechanistically probe these relationships and understand the functional repercussions of epigenetic dysregulation in cancer and aging. The CRISPRoff editor was developed in a collaboration between the Weissman and Gilbert labs as a single fusion protein containing the catalytically inactive dCas9, a repressive KRAB domain, and DNA methyltransferase domains. Transient expression of RNA-guided CRISPRoff achieves robust and heritable gene silencing in human cells, likely as a product of the synergistic spatiotemporal relationship between the coupled domains. Using a CRISPR-based screening approach, I plan to uncover and mechanistically characterize additional cooperative protein interactions which facilitate the establishment and maintenance of long-term transcriptional memory.

Project Title: Development of T cell receptor gene therapy for prostate cancer

My research aims to identify prostate cancer-reactive T cell receptors and their cognate antigens, thereby enabling the design of novel TCR gene therapies and dendritic cell-targeted vaccines.¬† I am also using protein engineering to improve the safety and efficacy of T cell receptors in such therapies and to extend these therapies to other widely-prevalent cancers of epithelial origin.

My training began at the University of California, Davis, where I was introduced to biochemistry by my undergraduate mentor, Robert Fairclough.¬† After UC Davis, I spent two years in Washington D.C. before joining the Stanford Biochemistry Department as a graduate student.¬† There, I worked with my advisor, Chaitan Khosla, on celiac sprue, an autoimmune-like disease in which dietary gluten precipitates an inflammatory immune response in susceptible individuals.¬† This research piqued my interest in how immune responses are shaped by foreign material, and in the potential for using bacterial and viral vectors to augment immunity to pathogens and to mitigate autoimmunity.¬† As a deleterious self pathogen, cancer is a uniquely challenging target of this engineering immunity approach. When not working, I enjoy discovering new activities in the L.A. area with my wife, Carol San, who is an occupational therapist.

Oregon State University

Project Title: Resolving cardiac Protein Kinase A signaling using a stable phosphoserine analog in mammalian cells

Jane Coffin Childs Fellow Jenna Beyer, Ph.D. believes that we are in a golden age of chemical biology, which is a field that uses chemical approaches to manipulate and understand complex biological systems. The illuminating tools that Beyer developed during her Ph.D. research and is developing during her Robertson Foundation – Jane Coffin Childs Fellowship, are unquestionably helping this field shine bright.

During her graduate work in George Burslem’s lab at the University of Pennsylvania she generated a new way to edit protein sequences directly inside living mammalian cells. This method quickly adds chemical labels, like biotin or fluorescent dyes, to proteins, which helps researchers study them using tools like pull-down assays or microscopy. Compared with older approaches, her method works faster, lets scientists control timing more precisely, and avoids using large tags or antibodies that can interfere with a protein’s normal function.

For the fellowship in Ryan Mehl’s lab at Oregon State University, Dr. Beyer will develop new tools to study phosphorylation at specific spots on proteins. Phosphorylation is when a phosphate group is added to an amino acid, and it can happen at many places on many proteins. Most current methods are “all-or-nothing”: they change a kinase, which is an enzyme that adds a phosphate group to a protein, and end up affecting lots of proteins at once. Beyer is creating a way to add a stable phosphate mark at one chosen site on one protein inside mammalian cells—more like a precise scalpel than a blunt tool. To show it works, she will first study how Protein Kinase A (PKA) may help protect against cardiovascular disease. Beyer’s approach should also help researchers understand the role of phosphorylation in many other diseases.

Divya Bezwada, Ph.D. Merck - Jane Coffin Childs Fellow

The Scripps Research Institute

Project Title: Illuminating cryptic functional pockets in the human proteome with electrophilic stereoprobes

Allostery is a fundamental biochemical process in which one site on a protein influences the function of a different site on the same protein, even if they are far apart. Given this relationship, allosteric sites are versatile drug targets as they can activate, inhibit, or even provide a new function to the protein depending on the specific ligand. Yet, therapeutic cooption of allosteric sites remains limited, in part, due to the prevalence of invisible, cryptic allosteric sites that only appear upon ligand binding.

Dr. Divya Bezwada aims to transform our understanding of cryptic allosteric sites in Dr. Benjamin Cravatt’s lab at The Scripps Research Institute. There Dr. Bezwada will use a chemoproteomic approach to investigate the prevalence of cryptic allosteric sites across protein paralogs. Bezwada’s research will provide first principles regarding the evolution of cryptic allosteric sites and develop novel chemical tools with broad relevance for biological understanding and therapeutic applications.

Bezwada provided novel insight into cancer metabolism during her doctoral research in Dr. Ralph DeBerardinis’ lab at UT Southwestern Medical Center. There she found that clear cell renal cell carcinomas (ccRCC) have defects in the electron transport chain which suppresses oxidative phosphorylation. This result is consistent with decades of research into cancer metabolism. Unexpectedly, Bezwada found that ccRCC metastases upregulate oxidative phosphorylation and that this change is functionally important for metastasis. Bezwada’s discovery has crucial and paradigm-shifting implications for cancer patient treatment. Now, Bezwada will leverage chemical biology techniques to make her next important insights into human biology and disease during her postdoctoral research.

Project Title: Role of circular RNAs in prostate cancer development and progression

The tremendous advances in DNA and RNA sequencing technologies have recently had a profound impact on our understanding of cancer biology and have revealed the importance of the non-protein-coding RNA molecular “space”. Disregarded for the past 20 years and considered products of aberrant RNA splicing, circular RNAs are nowadays acknowledged as an attractive type of noncoding RNA, probably involved in a multitude of cellular processes and able to play a critical role in human diseases._x000D_
_x000D_
The aim of my project is to uncover circular RNAs with diagnostic, prognostic and therapeutic potential in prostate cancer which represents the most common non-cutaneous malignancy and one of the leading causes of cancer-related deaths among men, both in Europe and in the United States. At the same time we aim to elucidate critical properties of this fascinating class of RNAs, opening new horizons for the entire cancer research field.

Project Title: Design of peptides to target protein-protein interfaces of membrane fusogens

I am broadly interested in the structure, function and dynamics of proteins that mediate signal transduction across the cellular membrane. These include membrane receptors, enzymes, ion channels and transporters. Since signaling is a dynamic process we need to study the ensemble of protein conformations and motions to understand how physical and chemical stimuli are converted into cellular information.

My graduate training was in solid-state NMR of membrane proteins. I currently use a combination of NMR, protein engineering and biophysics to gain quantitative insights into a family of transmembrane kinases that allow bacteria to sense and adapt to antibiotics in their environment.

Project Title: Decoding the thermodynamics of multi-component biomolecular condensates

Biomolecular Condensates are defined foci found in cells that have selectively concentrated biomolecules. The formation of biomolecular condensates via liquid-liquid phase separation, involving multivalent interactions among biomolecules, has emerged as an important principle for the organization of cellular structure and biochemistry. The molecular underpinnings governing the macroscopic behavior of multi-component condensates, formed by modular protein domains, remain poorly understood. There is limited understanding of how inter-domain binding affinities affect condensate energetics and dynamics, and whether the energetic behaviors can be inferred from known evolutionary relationships between the molecules. Studying these requires quantitative mapping of a phase diagram, which is a two-dimensional array of points for a two-component system and extends to being n-dimensional for n-components. The traditional methods used for mapping phase diagrams require substantial amounts of reagents and are labor-intensive. Hence, I have developed a high-throughput microfluidics-based platform in which hundreds of thousands of pL volume droplets can be made and analyzed as individual reaction chambers in a single experiment, enabling dense sampling of even high-dimensional phase spaces. With this method, I will be mapping phase diagrams and condensate dynamics for systems of increasing complexity. The characterization of the energetics of phase separation with a dataset of unprecedented scale will help in understanding (and eventually predicting) the behaviors of condensates from knowledge of the interactions and co-evolution of individual molecules.
