Marie-Dominique Filippi, PhD
Dr. Filippi is 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 her post-doc in the laboratory of Dr. David Williams, they 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, they 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, they 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.
Dr. Filippi's 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.
Hemostatic factors and arthritis pathogenesis
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.

Dr. Grimes has a broad background in hematopoiesis, molecular biology, and molecular oncology including modeling of hematopoiesis, myelopoiesis and leukemia. His work on the Growth factor independent-1 (Gfi1) transcriptional repressor protein has spanned the initial identification of Gfi1 in a model of leukemia and the role of Gfi1 in normal myeloid biology, to the identification of GFI1 mutations in patients with severe congenital neutropenia (SCN) and non-immune chronic idiopathic neutropenia of adults (NI-CINA). His work utilizes Gfi1 as a molecular probe to understand both normal myeloid development and innate immune action, as well as marrow failure and transformation.

focuses on genetic and epigenetic regulations of normal blood cell development and leukemia. His team demonstrated that AML1/CBFβ and mixed-lineage leukemia (MLL) protein form a regulatory complex, which is important for normal blood development and acts as a tumor suppressor in leukemia.
Research in Dr. Huang’s laboratory focuses on genetic and epigenetic regulations of blood cell normal development and leukemia. The lab 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).
The lab 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.

Nicolas Nassar, PhD
is a structural biologist interested in understanding the structure/function of signaling proteins, how they specifically bind and recognize regulators and targets, and in finding ways to inhibit their signaling in disease. His lab combines X-ray crystallography, site-directed mutagenesis, enzyme kinetics, and other biophysical techniques in its studies.
The major focus of our laboratory is to understand the regulation and signaling of the GTP-binding protein Ras and other Ras-like GTPases and to find small molecules that inhibit their activity in human cancers. Signaling by Ras-like GTPases is key to almost every cellular process and Ras is among the most mutated genes in human cancer. Despite this, a small molecule specifically targeting Ras activity has yet to enter clinical trials. Our research efforts encompass several methodologies, including protein crystallography, biophysical and biochemical studies, cellular functional assays, and ultimately, high throughput screenings of chemical libraries of small compounds that bind to and modulate GTPase signaling in cell line models.
We have identified several compounds that bind in vitro to Ras, inhibit cell proliferation of lung and other Ras-transformed cell lines, and decrease the activation of Erk-1/-2 and PI3K/AKT. Several ongoing questions stem from this finding: (i) we want to establish the mechanism of action(s) of these compounds. What gene or cellular process do they activate or silence downstream of Ras? Do they bind to Ras in cells and how specific is their binding? (ii) We are in the process of translating our findings to several disease models where Ras is hyperactivated, including both solid tumors such as lung adenocarcinomas, and MPNSTs and leukemias such as B-ALL.
We are also interested in the structure/function relationship of the multidomain protein tyrosine phosphatase (PTP) UBASH3B/Sts-1. Sts-1 was shown to be a target in triple negative breast cancer (TNBC). Our research is geared towards identifying small molecule inhibitors of the phosphatase activity of Sts-1. We have identified one such compound that inhibits the phosphatase activity of Sts-1 in vitro, decreases TNBC cell proliferation and decreases overall levels of phosphorylated proteins. We are currently testing structural analogs of our lead compound to further improve its potency.

Preclinical testing in neurofibromatosis tumors
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 and MEK as potential therapeutic targets 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 to 2004. Dr. Ratner is currently a professor in the Department of Pediatrics, Cincinnati Children’s Hospital Medical Center, University of Cincinnati, and the program leader for Cancer Biology and Neural Tumors Program in the Cancer and Blood Diseases 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 to 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 and the Jacob K. Javits Neuroscience Investigator Award (NIH-NINDS MERIT Award) in 2014.

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.

Daniel T. Starczynowski, PhD
Daniel T. Starczynowski, PhD, received his PhD in molecular biology from Boston University. He studied the NF-kB family of transcription factors and their role in B-cell lymphomas. During his postdoctoral fellowship at the BC Cancer Research Center, Dr. Starczynowski identified and characterized novel candidate genes in myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML).
Following his postdoctoral training, Dr. Starczynowski joined the faculty at Cincinnati Children’s Hospital Medical Center and at the University of Cincinnati as an assistant professor. Dr. Starczynowski’s laboratory is continuing to investigate the molecular and cellular basis of MDS. The current objective of his research program is to understand the contribution of MDS-associated miRNAs and their targeted genes to the pathogenesis of MDS and progression to AML. He hopes that understanding some of the molecular causes of MDS will enhance our insight into the biology of MDS, and provide novel targeted therapies.

Mei Xin, PhD
studies the mechanisms of heart growth, regeneration and vascular development. Dr. Xin’s research focuses on the identification and characterization of critical transcriptional and post-transcriptional molecules, as well as the signaling networks that control cardiovascular development and disease. These studies may provide insight towards therapeutic interventions for cardiovascular disorders.
Regulation of organogenesis such as cardiovascular and heart growth and regeneration, and the nervous system development
Mei Xin received her PhD from the University of Texas Southwestern Medical Center at Dallas. She completed her postdoctoral training in Eric Olson’s laboratory where she investigated microRNAs and Hippo signaling molecules regulating cardiovascular development and regeneration. In August 2013, Dr. Xin moved to Cincinnati Children’s Hospital Medical Center to study organogenesis including cardiovascular and peripheral nervous system development and diseases.
