Lionel Chow, MD, PhD, received his medical and graduate degrees from McGill University in Montreal, Canada, where his research focused on the regulation of T-lymphocyte signaling by the intracellular tyrosine protein kinases Lck and Csk.
Following his clinical training in pediatrics and pediatric hematology / oncology at the Hospital for Sick Children in Toronto, Canada, he moved to St. Jude Children’s Research Hospital in Memphis, Tenn., to pursue his research interests.
Chow's research interests have been centered on glioblastoma multiforme, a particularly devastating form of cancer in adults and children. His work has resulted in the development of a number of novel and robust laboratory models for this disease. Using these models and interfacing with clinical trials in the Neuro-Oncology Program as well as those from national consortia such as the Children's Oncology Group (COG) and the Pediatric Brain Tumor Consortium (PBTC), Chow’s laboratory will continue research in this area with the goals of better understanding the origins of this form of cancer and improving patient outcomes.

Jay L. Degen, PhD
Molecular genetics of plasminogen activation in development, hemostasis, and tumor progression; molecular genetics and biological role of plasminogen activation in development, hemostasis, wound repair, and disease
Jay L. Degen, PhD, is studying the regulation and biological roles of urokinase-type plasminogen activator (uPA) and tissue-type plasminogen activator (tPA), the two mammalian enzymes that convert plasminogen to the active serine protease, plasmin.
The PA/plasmin system of proteases is of particular interest because of its apparent dual function in the lysis of vascular fibrin clots (fibrinolysis) and the degradation of extracellular matrix in tissue remodeling and cell migration events.
Over the last few years, Dr. Degen's lab has generated and characterized gene-targeted mouse lines with deficits in the factors that are the foundation of the coagulation and fibrinolytic cascades, including fibrinogen-, plasminogen-, plasminogen activator-, and plasminogen activator receptor-deficient mouse lines.
These unique experimental animals are being intensively analyzed with regard to a wide range of phenotypic properties, including hemostasis, wound healing, angiogenesis and tumor biology.
Marie-Dominique Filippi, PhD
I am particularly interested in dissecting the molecular mechanism of hematopoietic cell migration, including neutrophils and hematopoietic stem cells in physiological settings. Migration is a critical function of hematopoietic cell in which actin cytoskeleton reorganization plays a central role. Because hematopoietic cells are utilized for the therapy of multiple blood diseases and neutrophils are responsible for maintaining an immunocompetence status, understanding the molecular mechanism of normal hematopoietic cell functions is of potential therapeutic importance. The small RHO GTPase family, members of the Ras superfamily, including Rac, RHO and CDC42, play key roles in regulating many of these functions. During my post-doc in the laboratory of Dr David Williams, we have demonstrated that two highly related proteins, Rac1 and Rac2, of the small Rho GTPase family, have distinct functions in the control of hematopoietic cell functions. In particular in neutrophils, we have shown that both Rac1 and Rac2 regulate cell migration but with distinct mechanism (Gu and Filippi et al, Science 2003) both in vitro and in vivo. In addition to this work, we have dissected the sequence/determinant specificity of Rac2 versus Rac1 functions in neutrophils and demonstrated that Rac2 controls its functions, at least in part, by distinct subcellular distributions of these GTPases (Tao et al, Blood 2002, Filippi et al, Nat Immunol 2004), highlighting one important mechanism controlling cellular functions. My laboratory, in collaboration Dr. Yi Zheng, is now focused on determining the role of CDC42 and RhoA in neutrophil migration and in determining specifically the role of RhoA in hematopoietic stem cell migration and proliferation using gene targeted knock out mice for CDC42 and RhoA and their respective regulator CDC42GAP and 190RhoGAP. These studies will use in vitro and in vivo assays of cell migration as well as immunofluorescence microscopy to study cytoskeleton rearrangement associated with cell migration. The long term goal of these studies is to identify new molecular targets of potential therapeutic importance.

Matthew J. Flick, PhD
is working to understand how hemostatic factors in the blood that are responsible for clotting also drive inflammation in the context of infection and diseases such as arthritis and fatty liver disease.
Research Interests and Focus:
1. Activation of the coagulation system, including the central coagulation protease thrombin, is a prominent feature of both human rheumatoid arthritis and experimental inflammatory arthritis. The long-term goal of Dr. Flick's research program is to determine how thrombin drives inflammatory joint disease. The proposed work will fill significant gaps in the understanding of the interplay between the thrombin- fibrinogen axis and arthritic disease, and may provide the proof-of-principle for the use of novel "customized" thrombin mutants with selected substrate specificity to treat arthritis.
2. The pervasive gram-positive bacteria Staphylococcus aureus is a common pathogen that is the causative agent for a wide spectrum of diseases including skin infections, pneumonia, bacteremia, toxic-shock syndrome and sepsis. Notably, this pathogen has evolved and maintained a number of proteins that directly engage the host hemostatic system, including factors that directly interact with the host coagulation factor fibrinogen. The long-term goal of his research program is to understand how bacterial derived proteins interact with host factors to promote bacterial virulence in the context of blood-born infections. This work will provide novel insight into the molecular pathways by which S. aureus invades and disseminates within host tissues and may shed light into novel strategies for eliminating this potentially devastating infectious agent.
3. Obesity is a worldwide epidemic linked to numerous disease sequelae, including non-alcoholic fatty liver disease (NAFLD). This spectrum disorder can progress from the simple accumulation of triglycerides within hepatocytes (i.e., steatosis), to inflammatory steatohepatitis, to organ failure secondary to irreversible liver fibrosis and cirrhosis. Dysregulation of the coagulation system has been documented in both patients with fatty liver disease and animal models of NAFLD, but any contribution to disease progression has remained largely undefined. Using a murine model of high fat diet (HFD)-induced NAFLD, they are testing the hypothesis that thrombin activity and fibrin deposition drive local inflammatory events promoting the progression of steatosis and steatohepatitis. Comparative studies of wild-type mice with genetically imposed deficiencies or functional alterations in prothrombin, fibrinogen and other associated coagulation factor components suggests that the thrombin-fibrinogen axis influences NAFLD pathogenesis by controlling local inflammatory processes that drive steatosis and by an unanticipated and unknown mechanism tying fibrin(ogen) to HFD-induced weight gain/obesity. Their research has far-reaching implications not only for the treatment and prevention of fatty liver disease, but also for all the downstream sequelae of obesity and even the development of diet-mediated weight gain itself.

The cloning and characterization of oncoproteins and tumor suppressors over the last 25 years has not only resulted in a greater understanding of the molecular mechanisms of transformation, but it has also provided a large set of therapeutic targets. Our lab is interested in the progression of a cell with a single genetic lesion to an invasive cancer with multiple genetic alterations. We focus on the Growth factor independence-1 (Gfi1) transcription factor, which is poorly oncogenic alone, but which potently collaborates with well known oncoproteins such as c-MYC. Gfi1 is the most frequently targeted gene in Moloney murine leukemia virus-induced tumors and induces tumor progression to cytokine-independent growth. In contrast, loss of Gfi1 in hematopoietic stem cells induces cell cycle progression and eventual bone marrow failure; implicating Gfi1 as a tumor suppressor in such cells. Gfi1 null mice have no mature neutrophils, and we have identified humans with Severe Congenital Neutropenia (SCN) and Non-Immune Chronic Idiopathic Neutropenia of Adults (NI-CINA) bearing mutations in Gfi1. Interestingly, such patients are at increased risk for the development of myelodysplastic syndromes and acute myeloid leukemia. We have recently generated the first mouse model of Severe Congenital Neutropenia through the expression of mutant Gfi1 proteins in primary murine hematopoietic cells. Moreover, we are utilizing mouse models of human cancer to assess the risk of Gfi1 mutant humans for the development of acute myeloid leukemia.

Nicolas Nassar, PhD
Nicolas Nassar, PhD is a structural biologist interested in the structure/function of signaling proteins and in finding ways to inhibit their signaling in disease. More specifically, we are interested in how a given protein specifically binds and recognizes its regulators and targets. We have over the years focused on Ras-like GTPases. Recently, however we have been interested in a new family of protein tyrosine phosphatases (PTPs). We combine X-ray crystallography, site-directed mutagenesis, enzyme kinetics, and other biophysical techniques in our studies.

Development of the nervous system; peripheral nerve tumor formation
Genetic mutations in tumor suppressor genes
Dr. Nancy Ratner PhD, is interested in understanding mechanisms of peripheral nerve tumor (neurofibroma) formation in Neurofibromatosis type 1 (NF1), a common inherited disorder in which children are predisposed to cancer of the nervous system, to learning problems, bone disorders, and other cancers. She identified EGFR as a potential therapeutic target in NF1 peripheral nerve tumorigenesis, and has developed cell culture and mouse models of NF1 nerve tumorigenesis. Her laboratory has also used analysis of gene expression to identify critical genes in neurofibroma and their malignant derivatives, MPNST.
Dr. Ratner received her bachelor's from Brown University, her doctorate from Indiana University, and was a postdoctoral fellow at Washington University in St. Louis. She was a member of the faculty at the University of Cincinnati from 1987 - 2004. Dr. Ratner is currently a professor in the Department of Pediatrics, Cincinnati Children’s Hospital, University of Cincinnati, and the program leader for Cancer Biology and Neural Tumors Program in the Cancer and Blood Disorders Institute where she holds the Beatrice C. Lampkin Endowed Chair in Cancer Biology and serves as PI of the NINDS P50 “Cincinnati Center in NF Research”.
Dr. Ratner is an active member of the International Consortium on the Molecular Biology of NF1, NF2, and schwannomatosis and was a member of the advisory board for the National Neurofibromatosis Foundation (now Children’s Tumor Foundation) from 1989 – 2007. She chaired the Department of Defense Neurofibromatosis Research Program Integration Panel in 2008, and currently serves as a member of the James McDonnell Brain Tumor Research Advisory Board. She received the von Recklinghausen Award from the Children’s Tumor Foundation in 2010.

Damien Reynaud, PhD
is an experimental hematologist interested in dissecting the cell-intrinsic and micro-environmental cues that regulate normal and pathological blood production. His research is focused on the molecular mechanisms that control normal B cell lymphopoiesis and how corruption of these mechanisms contributes to the development of acute lymphoblastic leukemia in children and adults.
Dr. Reynaud’s long-standing research interest is to understand the mechanisms controlling cell fate decisions in the hematopoietic system. During his graduate and post-graduate training, he worked to decipher the transcriptional regulatory networks that (i) control self-renewal activity and lineage specification in hematopoietic stem cells and (ii) regulate progenitor differentiation during the establishment of the natural and adaptive immune system. More recently he investigated the deregulation in stem and progenitor cell activity that, in adults, leads to the development of abnormal hematopoiesis and eventually to chronic myeloid leukemia. This work uncovered an unexpected contribution of the pro-inflammatory environment to leukemia development. Notably he identified a novel function for the pro-inflammatory cytokine IL-6 in reprogramming the fate of an early leukemic progenitor by promoting myeloid development at the expense of lymphoid differentiation. Following this work, the overall goal of his research at Cincinnati Children’s Hospital Medical center is to characterize how micro-environmental signals regulate normal B lymphoid and how corruption of these signals contribute to the initiation, maintenance and progression of acute lymphoblastic leukemia.
