Christina Towers, PhD

Assistant Professor, The Salk Institute

Towers__Christine-200x300

I am an assistant professor at the Salk Institute of Biological Studies in San Diego, California. After completing my PhD at the University of Colorado, I went on to pursue my post-doctoral studies also at The University of Colorado in Dr. Andrew Thorburn’s lab. During this time, I developed unique CRISPR/Cas9 tools to understand the recycling process, autophagy, in cancer cells. My work uncovered novel mechanisms that cancer cells can use to adapt to and circumvent autophagy inhibition. As a post-doc I was awarded a number of fellowships including the American Cancer Society Fellowship as well as the K99/R00 transition award from the NCI. I launched my lab at the Salk this July and we are excited to dive deeper into cancer cell metabolism and autophagy using optogenetics, single cell tracing, and high-resolution microscopy.

In the Towers lab we study cellular recycling processes in cancer cells. In one such mechanism – Autophagy – double membrane vesicles target cytoplasmic material for degradation via the lysosome. This process is important in many cancer cells as they must be able to recycle their own nutrients to support cellular metabolism when growing in nutrient poor environments like a solid tumor. Moreover, autophagy is also important for clearing damaged organelles and other macromolecules to maintain cellular homeostasis. Pharmacological agents to target these pathways are moving forward in clinical trials to treat a variety of different types of cancer, however initial results have been lukewarm. We discovered that cancer cells can adapt to autophagy inhibition and co-opt other cellular processes to survive. We are interested in the specific mechanisms autophagy-dependent cancer cells can employ to maintain organelle homeostasis and generate nutrients when autophagy is blocked. In particular, how can cancer cells avoid the buildup of damaged proteins or mitochondria – two molecules autophagy is necessary for the clearance of – when autophagy is inactivated? How do cancer cells adapt in this context? Do these mechanisms of adaptation predict patient response to autophagy inhibition? Can we target these adaptations to improve cancer patient outcome?    Fellows Class of 2022

I would not be where I am today without fantastic mentors during my PhD and Post-Doc studies. These experiences have strongly shaped my views on mentorship today. I am deeply committed to being an attentive, compassionate, and encouraging mentor to my own trainees to help them achieve their unique career goals. But I also recognize that as junior PI, I am still in need of strategic mentorship. This can be much harder to find at this level of my career than when mentorship was more structured during my PhD studies for example. The Keystone Fellows program has been fantastic in providing a structured mentorship program for me and I am so grateful for this opportunity."

"Genetically engineered T-cell immunotherapies, particularly chimeric antigen receptor (CAR) T-cells, have been remarkably successful treatments for relapsed and refractory B-cell malignancies, such as leukemia and lymphoma, and multiple myeloma. However, these therapeutics face several obstacles that prevent successful treatment of tumors from solid organs, including a requirement for enhanced tumor-specificity, infiltration into and resiliency within hostile microenvironments, and overcoming immune dysfunction. The Posey laboratory investigates the challenges limiting cellular immunotherapy and develops strategies to triumph these obstacles with a special focus on the role of glycans in immune activation and suppression and cellular differentiation. We are driven to these challenges through a passion to improve treatment outcomes for cancer patients."

Stacey Finley, PhD

Gordon S. Marshall Early Career Chair and Associate Professor, University of Southern California

2016-finley

Stacey D. Finley, Ph.D., is an Associate professor in the Department of Biomedical Engineering at the University of Southern California. She is holder of the Gordon S. Marshall Early Career Chair and the Director of the Center for Computational Modeling of Cancer (http://modelingcancer.usc.edu). Dr. Finley has a joint appointment in the Mork Family Department of Chemical Engineering and Materials Science and the Department of Biological Sciences (Quantitative and Computational Biology section). She is also a member of the Norris Comprehensive Cancer Center.

Dr. Finley received her Bachelor's degree in Chemical Engineering from Florida A & M University in 2004. Her graduate studies were completed in 2009 in Chemical Engineering at Northwestern University and involved using computational tools to predict and estimate the feasibility of novel biodegradation pathways. Her postdoctoral studies at Johns Hopkins University focused on computational modeling of VEGF signaling pathways. She was awarded postdoctoral fellowships from the NIH National Research Service Award and the UNCF/Merck Science Initiative. Dr. Finley's current research applies a systems biology approach to develop molecular-detailed computational models of biological processes related to human disease. The main projects are focused on applying computational modeling to study angiogenesis, metabolism, and immunotherapy. Current projects study how these processes are exploited in cancer. The biochemical networks that regulate these processes involve numerous cell types, molecular species, and signaling pathways, and the dynamics occur on multiple timescales. Therefore, a systems biology approach, including experiment-based computational modeling, is required to understand these complex processes and their interconnectedness in cancer. Models can simulate biological processes under pathological conditions and predict interventions that restore normal physiology. Additionally, the models can identify which tumors will respond favorably to a particular therapy, aiding in the development and optimization of effective therapeutics. Fellows Class of 2016

Jamaine Davis, PhD

Assistant Professor, Meharry Medical College

2015-davis

Genome-wide sequencing initiatives have generated extensive amounts of genotypic and molecular phenotypic data, identifying genetic predispositions (mutations) for developing disease. However, the genetic background is different for every patient. The challenge, therefore, is to understand how to interpret this information to determine how select encoded proteomic variants can not only promote human disease but also influence its response to treatment, and then design effective therapies that are specific for each patient. This aspect of personalized medicine is critically important in the pursuit to eliminate health disparities. As such, major unanswered questions in the field are: how does breast cancer develop and why are certain patients resistant to established therapies?

Despite the significant advances in medicine, increasing evidence suggests a more personalized approach is needed toward treating the individual patient and not the general disease. To accomplish this, integrative approaches are being developed to better understand the molecular mechanisms of disease initiation, progression, as well as drug response. Since these mechanisms are largely studied on the genomic level, we do not yet have a clear integration of how mutations that cause changes in protein structure and can lead to such varied phenotypes, particularly in cancer. My background in enzymology, protein chemistry, structural and cellular biology uniquely positions me to pursue these questions from using a lens of structural biology. My laboratory investigates structural mechanisms of genome maintenance in chemo-resistant cancers, with the goal of defining novel targets for anti-cancer therapies against aggressive tumors.

Amanda M. Brown, PhD

Associate Professor, Johns Hopkins University School of Medicine

2014-brownResearch in the Brown lab focuses on how breach of the blood-brain-barrier by viral pathogens like the human immunodeficiency virus type 1 (HIV-1), alters brain homeostasis. Central to this research is acquiring a detailed mechanistic understanding of the pathways leading to sustained neuroinflammation. HIV-1 robustly infects microglia and macrophages, but not neurons and to a lesser extent, astrocytes. In the absence of antiviral treatment, in 20% of infected persons, severe encephalitis, memory impairment and debilitating gait abnormalities can occur. The use of small molecule inhibitors, which block discrete steps of the viral life cycle, has greatly reduced severe neurocognitive impairment. However, in a large fraction of infected persons, functional deficits remain.

The Brown lab is testing the hypothesis that ongoing low-level replication that persists in tissues including the brain, drives chronic activation of proinflammatory signaling. The ultimate aim of the research is to apply the knowledge gained to develop new and better treatments to ameliorate HIV-associated cognitive comorbidities. In order to identify the molecular mechanisms of neuroinflammation, reductionist strategies with physiologically relevant primary cell culture, and cutting-edge tools in neuroscience are used. At the same time humanized rodent models are employed to test potential hypotheses and/or validate findings in a living system that approximates, or models an aspect of brain disease, and possibly behavioral phenotypes seen in the context of human neuropathology and impairment.

For the last several years, the Brown lab has sought and made progress in understanding the role of the multifunctional protein, osteopontin (OPN), which is encoded by the SPP1 gene, in the nervous system. OPN has long been described in neurodegenerative disorders like Alzheimer’s and Parkinson’s disease, multiple sclerosis (MS), and fronto-tempro dementia as a putative biomarker. However, except for MS, there is a profound lack of insight into OPN’s mechanistic function (s) in the brain. Exciting recent findings from the Brown laboratory and their collaborators which used micro-PET-imaging on HIV-infected humanized mice, suggest that OPN is a master regulator of neuroinflammation.  Fellows Class of 2014

2014-roweMetabolic imbalance and mitochondrial dysfunction have been associated with the development of the metabolic syndrome and many of its contributing diseases (cardiovascular disease, obesity and type II diabetes). Restoration of normal metabolic balance and mitochondrial function are important factors to eradicating this disorder. To date, diet and exercise have been proven to be the best intervention in the treatment of the many of metabolic syndrome. However, many of the molecular mechanisms responsible for these improvements are poorly understood. The research interest of the laboratory focuses on understanding the molecular pathways that influence mitochondrial metabolism in response to diet and exercise, in order to improve mitochondrial function and reduce the deleterious effects of the metabolic syndrome. Specifically, the lab studies the PGC-1 family of transcriptional coactivators and the molecular pathways they regulate in striated muscle to maintain normal mitochondrial function (including biogenesis, oxidative capacity and dynamics) and normal metabolic function. The laboratory utilizes a variety of molecular techniques, cell-based assays as well as genetically modified mouse models. Various projects are available in the laboratory, including 1.) The study of mitochondrial dynamics in response to exercise, 2.) The effect of exercise on angiogenesis and mitochondrial metabolism, 3.) The characterization of new regulators of mitochondrial metabolism in striated muscle.  Fellows Class of 2014

Alexis Stranahan, PhD

Associate Professor, Medical College of Georgia at Augusta University

2011-stranahan

Neurons are exquisitely sensitive to cellular stress due to the metabolically demanding processes underlying synaptic transmission. My lab studies the regulation of synaptic plasticity and cognition by metabolic stress at the behavioral, electrophysiological, and cellular levels. We define 'metabolic stress' broadly to encompass responses to exercise and caloric restriction at one extreme, and changes occurring in obesity and diabetes at the opposite end of this continuum. Our long-term goal is to understand how neurons, glia and cerebrovascular cells sense and respond to homeostatic challenges. Fellows Class of 2011

De' Broski Herbert, PhD

Associate Professor, University of Pennsylvania School of Veterinary Medicine

2009-herbert

Due to an inherent fascination with parasitic helminthes, De’Broski R. Herbert earned a B.S. in Microbiology from Xavier University of Louisiana (1994) and a Ph.D. in Immunology from Thomas Jefferson Medical College (2000). His thesis work demonstrated a critical role for IL-5, B-1 lymphocytes, and eosinophils in host-protective immunity against Strongyloides stercoralis (J Immunol. 2000 Oct 15;165(8):4544-51).

As part of a life-long dream, De’Broski spent several years in South Africa to complete his post-doctoral training at the University of Cape Town in the laboratory of Frank Brombacher Ph.D. This resulted in seminal work that demonstrated IL-4/IL-13-driven alternative macrophage activation controls lethal immunopathology during Schistosoma mansoni infection (Immunity. 2004 May;20 (5):623-35).

Subsequently, he joined the laboratory of Fred. D. Finkelman M.D. and published multiple studies focused on the importance of IL-4/IL-13 in driving host-protection against parasitic helminthes through direct regulation of tissue macrophage function (J Immunol. 2010 Jun 1;184(11):6438-46) and mucosal epithelia (J Exp Med. 2009 Dec 21;206(13):2947-57).

As principal investigator of his independent laboratory at Cincinnati Children’s Research Foundation, his work focused upon elucidating mechanisms of innate Type 2 cytokine regulation by Trefoil factor family proteins (J Exp Med. 2012 Mar 12;209 (3):607-22) and immunosuppressivemacrophage subsets in the context of helminth infection and allergic inflammation (Eur J Immunol. 2011 Jul;41(7):2000-9,
Am J Pathol. 2012 May;180(5):2001-8).

Currently positioned as associate professor of Infectious Immunology in the Department of Pathobiology at UPENN, his laboratory is investigating mechanisms of host protection against helminthes, Type 2 inflammation, and the resolution of chronic mucosal inflammation in several model systems.

Nicole LaRonde-LeBlanc, PhD

Assistant Professor, University of Maryland

2009-larondeMy laboratory is focused on the study of molecules required for the synthesis of new ribosomes. A proliferating cell devotes 75% of its energy towards making these machines for protein synthesis. In the process of assembly of this large complex of RNA and proteins, an estimated 400 ribosome processing factors are utilized in humans. Although many of these proteins and protein-RNA complexes have been identified, for several of them their exact function in the process remains unknown. We are interested in determining the molecular details of how these macromolecules function in eukaryotic organisms.

We are currently studying the structural biology of the RIO kinases, a group of ancient atypical serine protein kinases, and Nep1, a putative RNA methyl transferase. These molecules are essential for the processing of the small ribosomal, or 40S, subunit. The role of these molecules in the synthesis of ribosomes is still unclear, but armed with X-ray crystal structures we are probing the interactions between these molecules and the rRNA, as well as with other molecules involved in the process. Our work thus far has elucidated how the RIO kinases interact with ATP and the pre-mature small subunit of the ribosome, and how Nep1 interacts with RNA. Our current work involved using these structures to guide questions in biochemical and biological contexts.

Although we are interested in the basic science surrounding these molecules, we are also interested in how these molecules may be targeted for therapeutic use. Ribosome synthesis is indispensable to highly proliferating cells, such as cancer cells. The inhibition of ribosome synthesis has the potential to inhibit cellular proliferation, and thus cancer cell progression. Therefore, our structural work also involves the design of small molecule inhibitors of ribosome synthesis.

In addition to our work in ribosome synthesis, we have determined the X-ray crystal structures of several molecules of biological importance as part of collaborative research programs. Fellows Class of 2009
