Biography
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, Tennessee to pursue his research interests. Dr. 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), Dr. 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.

Biography
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.

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.

Biography
Grimes Laboratory: 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.

Research in Dr. Huang’s laboratory focuses on genetic and epigenetic regulations of blood cell normal development and leukemia. We first demonstrated that AML1/CBFβ (a hetero-dimer transcription factor) and Mixed-Lineage Leukemia (MLL) protein (an enzyme which methylates lysine 4 of histone H3 tails), form a regulatory complex, which is important for normal blood development and acts as a tumor suppressor in leukemia. Mutations in either one of these three genes account for majority of acute myelogenous leukemia (AML), acute lymphoblastic leukemia (ALL) and myelodysplastic syndromes (MDS).
We also found that the AML1/CBFβ/MLL complex regulates another transcription factor, PU.1, through the upstream regulatory region of the PU.1 gene and that the epigenetic changes of the histone tails occurring in the PU.1 regulatory region correlate with the PU.1 expression level. PU.1 expression level changes are critical for blood cell differentiation and dysregulation of PU.1 dosages leading to leukemia.
This research will provide new insight into the interplay between genetics and epigenetics in normal blood development and leukemia. It will also help to develop generic drugs for most of the AML, ALL and MDS, which will benefit the future clinical treatments.

Biography
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.

Biography
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.
