Research News & Articles
2015 APR Annual Report
Translational Hematology & Oncology Research
- Dr. Saunthararajah completed phase I study of a novel pharmacologically rational oral non-cytotoxic epigenetic therapy in collaboration with other investigators. He has subsequently obtained funding for a phase II evaluation in pancreatic and lung cancer as well as myeloid and lymphoid neoplasia alone or in combination with immune check point inhibitors. The resultant trials will be performed nationally in a multicenter setting.
- Discovery of new familial leukemogenic mutations and a novel class of tumor suppressor genes, RNA helicases, in myeloid leukemias. This work was published in Cancer Cell. DDX41 mutations convey familiar predisposition to adult onset AML and acquisition of somatic bilallic DDX41 mutations. This discovery has already led to a proposal for a new AML category in WHO classification called "familial AML" including RUNX1, CEBPA, DDX41 and ETV6.
- Maciejewski, MD, PhD, collaborated with researchers from Harvard University (Dr. Weinstock) to discover mutations and clarify the mode of action of the novel tumor suppressor gene GPB1 published in Nature Medicine.
- Dr. Saunthararajah's invention showing means of resistance to the only drugs effective in MDS, DNMT1 depleting agents, was a feature in the Best of ASH.
- Dr. Maciejewski's program in aplastic anemia has contributed to the discovery of frequent clonal events in the otherwise considered benign aplastic anemia - a paradigm shifting discovery with regard to the understanding of the pathogenesis of this disease. This work has been reported in New England Journal of Medicine.
- Dr. Saunthararajah established rationale and completed phase I/II results of a novel non-cytotoxic therapy for MDS creating a new therapeutic paradigm for this disease. This work led by Dr. Saunthararajah was reported in Journal of Clinical Investigation.
- Dr. Saunthararajah has filed an invention disclosure for the first inhibitor of SWIF/SNF ATPase inhibitor, an entirely novel therapeutic concept and class of agents.
- Leukemia/MDS genomic initiative results. Next generation sequencing technology has been made available to TCI researchers and clinicians. The results of the large exome sequencing study have been presented at ASH and are under review in Nature Medicine.
- THOR Department received a multi-PI "LRI Centers of Excellence in CMML" grant.
- Dr. Saunthararajah presented Best of ASH abstract at the 2015 Annual ASH Meeting.
- Dr. Maciejewski has been appointed Chairman of the Myeloid Neoplasia Committee of the American Society of Hematology.
- Dr. Maciejewski has been appointed as a permanent member of the Molecular and Cellular Hematology Study Review Section of the National Institutes of Health.
- THOR has published high impact papers in top ranking journals: NEJM (1), Cancer Cell (1), Cell (1), Nat Med (1), JCI (1), J Exp Med (2).
- THOR has developed and obtained IRB approval for a STANDARD tissue collection/repository protocol available for use by Disease Programs throughout TCI.
- THOR Research Grants Administration Office submitted 35 initial proposals (~27 mil) for THOR and 20 proposals (~8 mil) for non-THOR TCI members in addition to managing grant requirements for CCCC p30 and NCTN and other ongoing collaborative projects.
Formation of AGING/LONGEVITY DRUG DEVELOPMENT CENTER. This new initiative is based on the theory that prevention/retardation of the aging process is a major contributor to delaying the occurrence of hematologic malignancies in the elderly. The center incorporates the skill of the drug development center and reaches across multiple departments within TCI and LRI.
Establishment of MEDICINAL CHEMISTRY CORE with 3 new faculty:
- Dr. Jim Phillips: Synthetic organic chemist
- Dr. Jha Babal: In silico chemist/structural biology

Our research focuses on identifying the genomic abnormalities which give rise to therapeutic resistance in cancers and using this information to develop personalized therapies in a new strategy of biologically-guided treatment. As a Radiation Oncologist with training in radiation science, genomics, and cellular and molecular biology, Dr. Abazeed uses his experience in both patient care and basic science to develop a clinically relevant research program to study cancers and to translate laboratory discoveries into potential improvements in clinical care. The goal of our efforts, through a highly integrative and collaborative research program, is to nominate therapeutic targets in cancer and to motivate an evolution in the use of therapy from a generic approach to one in which therapies are selected based on the molecular alterations identified in a patient’s tumor. This approach allows us to enhance efficacy and limit toxicity in the context of a new approach of precision therapy. We have recently developed a large body of data annotating the radiogenomic landscape of cancer and we are focused on studying recently discovered genomic alterations in order to better understand and therapeutically target cancers.
The main focus of our research is novel target discovery and small molecule therapeutic development against myeloid malignancies and hematological disorders. We are heavily invested in understanding the fundamental mechanism of the gain of survival function in cancer cells upon therapeutic treatment. We study cellular innate immunity and transcriptional reprogramming in cancer cells upon treatment with DNA damaging agents. We use structure guided small molecule design and synthesis to target oncogenic factors responsible for aberrant activation of cell survival. We use various state-of-the-art techniques in structural biology, biochemistry and molecular biology to tease out the detailed mechanism of cancer cell survival. Our long term goal is to develop a new generation of therapeutics against myeloid malignancies and hematological disorders.
We have an interest in inositol polyphosphate kinases, their enzymatic products, and the pathways by which they affect cell growth and apoptosis. Ongoing studies with IP6K2 knockout mice suggest that they are predisposed to development of head and neck carcinoma.
We are also utilizing a genetic approach to identify genes that may alter the phenotype of myelodysplastic syndrome and resultant bone marrow failure syndrome. Another focus of the laboratory is tumor induced angiogenesis. Utilizing murine models, we have shown that myeloid derived suppressor cells are early promoters of angiogenesis in renal cell carcinoma.
Our laboratory investigates pathogenesis of several hematopoietic disorders including aplastic anemia, paroxysmal nocturnal hemoglobinuria, myelodysplastic syndrome and chronic and acute myeloid malignancies. The research areas include stem cell biology, molecular pathogenesis of malignant transformation including mutations and DNA damage and immune mechanisms of hematopoietic suppression leading to deficient blood cell production. We apply high density DNA arrays, methylation arrays, high throughput sequencing, flow cytometry and various cell culture systems. All research projects are highly translational and have a goal to identify diagnostic and therapeutic targets in patients.
The McCrae laboratory focuses on vascular cell biology in pathologic disorders through study of endothelial cells in vitro and in vivo. We are primarily interested in two areas. One is the antiphospholipid syndrome (APS), a clinical disorder characterized by thrombosis and recurrent fetal loss. “Antiphospholipid” antibodies are actually not directed against phospholipid, but a phospholipid binding protein, β¬2-glycoprotein I (β2GPI).
We have shown that β2GPI binds to endothelial cells through cell surface annexin A2 (AII) and that cross linking of AII-bound β2GPI by bivalent anti-β2GPI antibodies leads to activation of endothelial cells; our focus is to define the mechanisms by which β2GPI/AII cross-linking leads to transmission of a transmembrane signal. We have also observed increased numbers of endothelial cell and platelet-derived microparticles in plasma of patients with APS.
Our other major interest is in the role of kininogen, a member of the intrinsic coagulation pathway, in regulation of angiogenesis. Upon cleavage, high molecular weight kininogen (HK) is converted to cleaved kininogen (HKa) with the release of bradykinin (BK). We have observed that HKa causes rapid apoptosis of proliferating endothelial cells, and inhibits angiogenesis. We have produced a kininogen deficient mouse, which displays a pro-angiogenic phenotype, and are exploring the mechanisms underlying this phenotype, which contrasts with other animal models of kininogen deficiency. Microarray studies suggest altered expression of a number of genes in tumors from kininogen deficient mice.
Clinical Focus: Genitourinary Cancers (e.g., Bladder, Prostate, Urethra, Kidney)
Research Mission: To improve outcomes and minimize treatment related toxicity through a better understanding of the interaction between radiation, the tumor environment, and the epigenome.
Research Overview: Cancer is fundamentally a genetic and epigenetic disease characterized by pervasive genomic disorganization. Epigenetic therapies are poised to change the landscape of cancer treatment and we have a unique opportunity in Radiation Oncology to harness these breakthroughs. In my laboratory we are interested in addressing two areas of clinical need in radiation oncology: 1) the utilization of epigenetic therapies (e.g., DNA methylation inhibitors, bromodomain inhibitors, HDAC inhibitors) and global modifiers of epigenetic programs (e.g., Methyl-CpG binding Proteins, Steroid hormone inhibitors) to enhance the efficacy of radiation therapy and 2) the need for reliable epigenetic biomarkers of disease burden, response to radiation therapy, early relapse, risk of radiation related normal tissue injury, and the underlying biology that distinguishes indolent from lethal phenotypes.
Our laboratory’s primary disease focuses include myelodysplastic syndromes, chronic and acute myeloid malignancies, myeloproliferative syndromes, multiple myeloma, and B-cell lymphomas. Our laboratory provides medicinal chemistry expertise. Working collaboratively with the principal investigators in the department of Translational Hematology and Oncology Research, our efforts are focused on using relevant biomarkers discovered within the department to develop more rationally designed small-molecule drugs. Present investigations involve the design and synthesis of LSD1 inhibitors, RNA helicase inhibitors, selective spliceosomal inhibitors, and ubiquitin transfer facilitators.
A major objective of our work is to develop therapy that selectively destroys malignant cells while sparing normal stem cells. To this end, our work covers a number of aspects: one aspect focuses on understanding the mechanisms by which malignant stem cells self-renew, and finding differences between malignant self-renewal and normal stem cell self-renewal. Another aspect focuses on identifying and developing drug-able compounds that target identified differences between normal and malignant self-renewal. A final aspect studies the pharmacologic properties and considerations of proposed agents to enable the clinical trials for selective malignant stem cell destruction. The other major objective of our efforts is to develop more effective methods for pharmacologic reactivation of fetal hemoglobin expression as a treatment for sickle cell disease and beta-thalassemia.
Clinical Focus: Sarcoma
Research Mission: To understand how cancers acquire resistance to targeted biological agents and radiation and to harness this knowledge to design better therapeutic strategies for our patients.
Research Overview: Cancer is a complex disease that is an aberration of our own tissues, but it still obeys fundamental biological rules. Our greatest challenge in the clinic is the emergence of resistance to our therapies, a process which is governed by Darwinian evolution. Using a suite of mathematical and experimental models, my laboratory seeks to deconvolute the complexity of the evolutionary process into fundamental principles. We aim to use this knowledge to then curtail the evolutionary process to increase the efficacy of targeted therapies and radiation. This same knowledge can be further harnessed to understand the differences in disease progression and therapy response on a personalized basis, so that the right treatment can be given to the right patient at the right time.
