Abstract

Genetics of PTEN and Molecular-Based Patient Care

Tumor suppressors act like automobile brakes to prevent cell overgrowth. Our project utilizes a single model tumor suppressor gene called PTEN as a model for translating laboratory discoveries to evidence-based patient care. Germline gene mutations represent faults or alterations in DNA, which is the stuff of genes. Germline mutations of PTEN cause Cowden syndrome (CS). CS which was believed to be rare, is actually under-recognized particularly by non-cancer genetics professionals and therefore, diagnoses are not made. This is rather dangerous because CS is a hereditary condition characterized by breast and thyroid cancers and perhaps cancer of the uterus.

Because PTEN-associated CS is so difficult to recognize the first objective of our study is to statistically and genetically model the clinical features of over 1000 patients with features reminiscent of CS so that the fewest and most parsimonious features may be objectively identified. Identifying these features will help primary caregivers identify such individuals for purposes of referral to cancer genetics professionals.

It is not known if women with only breast cancer and no obvious features of CS might have unsuspected germline PTEN mutations. Therefore, the second objective of our study is to examine a large population-based series of women diagnosed with breast cancer to see what proportion of such women have germline PTEN mutations. Having germline PTEN mutations would not only put them at increased risk of other cancers, but also has implications for their families.

Somatic gene mutations are present only in cancer cells and cannot be inherited. Because somatic mutations of PTEN have been described in sporadic (not familial, not genetic) breast tumors, our third objective is to seek out and characterize non-traditional, non-genetic alterations of PTEN as new targets of therapy and prevention.

Abstract

Novel Strategies to Improve Allogenic BMT

Allogeneic bone marrow transplantation (BMT) is an important curative therapy for a number of hematologic malignancies, but it is complicated by Graft-vs.-host disease (GVHD) and idiopathic pneumonia syndrome (IPS). Research in Dr. Ferrara's laboratory has demonstrated agents that protect the GI tract provide new opportunities for prevention of the cascade of inflammatory cytokines that can reduce these complications. This project will support several clinical trials designed to test novel agents that can reduce the toxic complications of BMT. Funding from the Doris Duke Charitable Foundation will facilitate the laboratory evaluation of patient samples from all of these trials, support the design of new trials of these agents and enhance the mentoring of junior faculty members involved in translational BMT studies.

Keratinocyte growth factor (KGF) is a protein that stimulates the grown of epithelial cells including those of the GI tract. Recombinant human KGF (rHuKGF) protects the GI tract, prevents severe GVHD and preserves donor T cell function needed for the beneficial graft-versus-leukemia effect. Specific aim 1 is to perform a single arm, dose-esclation, safety trial of rHuKGF plus standard GVHD prophylaxis.

Tumor Necrosis Factor (TNF)-alpha is a major inflammatory cytokine effector of these two disorders. Neutralization of TNF-alpha with soluble dimeric TNF-alpha binding protein (etanercept) can prevent both GVHD and acute lung injury in preclinical studies. Specific Aim 2 is to perform a single arm Phase I-II trial of etanercept plus standard treatment (steroids) to treat newly diagnosed GVHD. Specific Aim 3 is to perform a single-arm, open label Phase I-II study of etanercept plus standard treatment (steroids) to IPS after BMT.

Abstract

Clinical Translational Approaches to Therapy of Myeloid Blood Diseases

This is a highly integrated and synergistic proposal that covers the entire spectrum of clinical translational research in myeloid blood diseases. These include the myeloproliferative disorders (MPD), myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). Most adults and children who develop MPD, MDS or AML eventually succumb to complications related to their disease or therapy. Unfortunately, our therapeutic approaches to these diseases have changed little over the past two decades. There is thus a compelling need to develop more effective and less toxic therapies for these potentially fatal blood disorders.

We have devoted a substantial effort to understanding the genetic basis of these MPD, MDS and AML, with the hope that these insights will allow us to develop therapies that target the specific genetic defect that causes the disease. Molecular targeting may allow for more specific and less toxic therapies, and may improve outcome either alone, or in conjunction with more conventional therapies. To this end, this proposal utilizes a comprehensive clinical translational approach to these blood disorders, including (i) cloning of disease alleles, (ii) characterization of the transforming properties in cell culture systems, (iii) development and testing of specific inhibitors in the model systems for transformation, (iv) translation of inhibitors into clinical trials. We have already demonstrated proof-of-principle for this approach in the application of FLT3 inhibitors in therapy of advanced MDS and AML.

An attribute of this application is the seamless dovetailing of laboratory and clinical investigation - this is not a unidirectional approach from bench to bedside, but rather a highly interactive and interdependent team of young investigators that derive synergy from the crosstalk between the laboratory and the clinic. However, perhaps the most important strength of the proposal is the dedicated and devoted focus on the career development of the physician-scientists. I have a strong track record of nurturing and supporting the career development of female and male physician-scientists. With the resources of the DCSA, which are entirely devoted to the salary and laboratory support of an exceptionally talent group of medical students, medical residents, hematology/oncology fellows, and junior faculty, I hope to help build the next generation of physician-scientists who will realize our collective dream and fervent hope of developing cures for these devastating blood disorders.

Biography

Dr. Daniel Haber was born in Paris, France in 1957. He came to the US in 1973 to attend college at Massachusetts Institute of Technology, where he received BS and MS degrees. He continued his studies at Stanford University under the Medical Scientist Training Program. He obtained his PhD in the laboratory of Dr. Robert Schimke in 1981, studying gene amplification as a mechanism of chemotherapeutic drug resistance, and received his MD in 1983. He subsequently completed a medical internship and residency at Massachusetts General Hospital, followed by a clinical fellowship in medical oncology at Dana Farber Cancer Institute (1986). Dr. Haber then pursued postdoctoral research training with Dr. David Housman at MIT, working on the characterization of the Wilms Tumor suppressor gene WT1. He was appointed Assistant Professor of Medicine at Harvard Medical School in 1991, and established his laboratory at the Massachusetts General Hospital Cancer Center to study the genetics of Wilms tumor and breast cancer. He was promoted to Associate Professor in 1996 and Professor in 2001. In addition, Dr. Haber serves as Associate Chief for Research in the Hematology Oncology Unit at MGH, as Chair of the Cancer Genetics Program for the Dana Farber-Harvard Comprehensive Cancer Center, and as Director of the MGH Center for Cancer Risk Analysis. He is on the Editorial Board of Cell and Cancer Cell, and serves as Genetics Editor for the New England Journal of Medicine. He has received numerous awards, including the McDonnell Cancer Scholar Award (1990), the American Association for Cancer Research and National Foundation for Cancer Research Professorship in Basic Cancer Research (2000), and a MERIT Award from the National Cancer Institute (2002). He was elected to the American Society for Clinical Investigation in 1995. He is the author of 122 publications dealing with various aspects of the genetics of pediatric kidney cancer and adult breast cancer. The Doris Duke Distinguished Clinical Scientist Award was awarded for his work on the characterization of CHK2, a cell cycle checkpoint kinase that is mutated in the germline of women with predisposition to breast cancer.

Abstract

CHK2: A Common Low Penetrance Familial Breast Cancer Gene

Germline mutations in BRCA1 account for ~50% of high risk familial breast cancer, while mutations in BRCA2 are responsible for ~25% of cases. These findings have provided important insight into the pathogenesis of breast cancer, and they have made it possible to offer genetic counseling to family members at risk, with consideration of preventive surgery, hormonal chemoprophylaxis, intensive screening regimens, and eventually the possibility of genotype-directed therapy. The etiology of familial breast cancer cases lacking mutations in the BRCA genes is uncertain, and the absence of clear genetic linkage to a third locus has led to the suggestion that these cases may result from a number of lower penetrance genes, which in aggregate, may contribute to both breast cancer kindreds, as well as individuals with less dramatic family histories. A major step in this direction has been the observation that 1% of the population carries a specific truncating mutation in CHK2 (1100delC), while this mutation is present in 5% of familial breast cancer cases (ie. a common low penetrant mutation). CHK2 encodes a kinase, which itself is activated by the DNA damage responsive kinase ATM, and which is capable of phosphorylating p53, CDC25 and BRCA1. As such, CHK2 is positioned at the intersection between DNA damage response sensors and the effectors of cellular checkpoints implicated in cell cycle arrest, apoptosis and DNA damage repair. Our laboratory was the first to identify mutations in CHK2, including 100delC which we discovered in a family with the multicancer phenotype Li-Fraumeni Syndrome, but which lacked the characteristic mutation in p53. CHK2 has now been shown to phosphorylate p53 at the critical 20Serine residue required for its activation following DNA damage. The recent discovery that the specific CHK2 mutation 1100delC is common in the population and confers a moderate risk for breast cancer has raised the possibility that additional mutations in this gene and in other related genes may play a significant role in human breast cancer. In this proposal, we propose 1. to undertake mutational analyses of CHK2 and related genes in familial breast cancer cases lacking mutations in BRCA genes; 2. to define the penetrance (ie. breast cancer risk) and clinical phenotype associated with these mutations; 3. to develop functional assays that allow interpretation of CHK2 missense mutations present in familial breast cancer cases; and 4. to use CHK2 as a model with which to explore how analysis of low penetrance mutations should be integrated into clinical practice. These questions will have significant impact, both in terms of high risk breast cancer care, as well as the more general integration of increasingly complex genetic information into the clinic.

Abstract

Genetics of Lipid Metabolism and Atherosclerosis

Atherosclerotic cardiovascular disease (ASCVD) remains epidemic in the U.S. and most of the world. Effective prevention requires accurate identification of those at risk and institution of therapies that reduce risk. Stabilization and regression of atherosclerosis require development of new therapeutic interventions that are effective and complement existing therapies. A better understanding of the genetics of atherosclerosis and its risk factors will provide greater ability to predict future risk as well as lead to new targets for therapeutic intervention. Plasma lipoprotein metabolism is intimately related to the development of atherosclerosis. Plasma low-density lipoprotein (LDL) cholesterol is directly associated and plasma high-density (HDL) cholesterol inversely associated with ASCVD. Reduction of LDL-C is proven to reduce risk although only by about one-third over 5 years. The effects of raising HDL-C are uncertain as highly effective HDL-raising interventions are not yet available. Our broad goal is to investigate the role of genetic variation in determining levels of LDL-C and HDL-C and translate those findings into new abilities to predict, prevent, and regress atherosclerosis.

Specific Aims:

  1. Determine the safety and efficacy of pharmacologic inhibiton of the microsomal transfer protein (MTP) in patients with homozygous FH. Investigate the effects of MTP inhibition in homozygous FH patients on in vivo lipoprotein metabolism and atherosclerosis.
  2. Investigate the molecular etiology of dominantly-inherited high HDL cholesterol using both linkage analysis and candidate gene approaches.
  3. Develop methods for quantitation of peripheral cholesterol mobilization and reverse cholesterol transport in humans and apply them to the investigation of existing and novel therapeutic approaches targeted toward HDL metabolism.

These studies work toward an era in which genetics will allow us to identify high-risk individuals well before their clinical event and to design new therapies that will allow us to effectively prevent and regress atherosclerosis.
