Colin Duckett, Ph.D

Colin Duckett, PhD.
Director of Program Development, North Campus Research Complex
Professor, Departments of Pathology and Internal Medicine

Dr. Duckett's laboratory is interested in studying how cells respond to internal and external cues, for example by undergoing a programmed form of cell death known as apoptosis, by modulating gene expression, or through the induction of proliferation. In normal cells these pathways are very tightly controlled, but one or more are deregulated in virtually all human diseases. Our specific interests are the study of a group of mammalian proteins called IAPs (Inhibitors of Apoptosis) which have collectively been shown to participate not only in apoptosis, but in intracellular signaling leading to transcriptional changes, as well as cellular proliferation and, most recently in copper homeostasis. Much of his current research is focused on the role of IAP proteins in cancer, especially prostate and breast cancer, with a particular emphasis on the potential of IAP antagonists as therapeutic agents, and additionally his lab is examining the role of specific IAPs in homeostatic regulation of lymphoid cells.

Related to their work on IAPs, the Duckett lab is also interested in studying the signaling pathways employed by the cell surface receptor, CD30, which is highly overexpressed in cells of Hodgkin's Disease origin, as well as certain non-Hodgkin's lymphomas including anaplastic large cell lymphoma. CD30 is an attractive target for these classes of lymphoma, because its expression is normally highly restricted in the body. Dr. Duckett is very interested in understanding the cellular effects of CD30-mediated signaling, especially as these signals are transduced through certain members of the IAP family, and his lab is most interested in examining the potential for this pathway to be exploited for therapeutic goals.

Elizabeth R. Lawlor, MD, PhD.

Elizabeth R. Lawlor, M.D., PhD.
Associate Professor, Department of Pathology
Associate Professor, Department of Pediatrics and Communicable Diseases

Dr. Lawlor's research focuses on studies of Ewing sarcoma, a very aggressive bone and soft tissue tumor that primarily affects children, adolescents and young adults. She is pursuing studies with stem cells in order to understand how the EWS-FLI1 oncogene can turn normal stem cells into Ewing sarcoma cells. In addition, her lab studies the contribution of epigenetic deregulation to the pathogenesis of cancer. Specifically, they are elucidating the contribution of polycomb gene deregulation in the origin and progression of Ewing sarcoma and determining how altered expression of the polycomb protein BMI-1 affects response to therapeutic agents. By evaluating the similarities and differences between normal stem cell development and cancer, the Lawlor lab is gaining insights into both the origins of pediatric sarcomas and the biology of cancer stem cells.

Mats Ljungman, PhD.

Mats Ljungman, PhD.
Professor, Radiation Oncology
Professor of Environmental Health Sciences, School of Public Health

Dr. Ljungman earned a Ph.D. degree from Stockholm University and performed postdoctoral research at Stanford University before starting as an Assistant Professor and advancing to Full Professor at the Department of Radiation Oncology and Environmental Health Sciences, University of Michigan.

The Ljungman lab has developed a suite of techniques aimed at obtaining a very detailed picture of many aspects of transcription and its regulation not available with other current techniques. These new techniques are based on the metabolic labeling of nascent RNA using bromouridine (Bru) followed by specific isolation of Bru-containing RNA and deep sequencing. The Bru-seq technology platform allows for the genome-wide assessment of the synthesis and stability of RNA, splicing kinetics, transcription elongation rates and the mapping of transcription start sites and enhancer elements. Using the Bru-seq platform, the Ljungman lab is in collaboration with Dr. Simeone's lab, exploring gene expression signatures in primary pancreatic tumor cell lines and together with Drs. Neamati's, Duckett's, Lawlor's and Newman's lab, exploring how these gene signatures correlate to drug sensitivity and signal transduction pathways. Bru-seq is also used to investigate the effects of radiation and chemotherapeutic drugs on gene expression in cancer cells and normal cells and to explore basic questions about the mechanisms of splicing and transcription elongation. As part of the ENCODE consortium the Ljungman lab contribute to the study of epigenetic regulation of gene expression. The Ljungman lab has collaborators in 10 different countries using the Bru-seq techniques.

In collaboration with the Simeone lab, the Ljungman lab studies the molecular functions of the newly identified oncogenic protein ATDC and its role in the DNA damage response. ATDC is a potential therapeutic target in pancreatic, bladder and potentially other cancers and efforts are underway, in collaboration with Dr. Neamati's lab, to develop small molecule inhibitors of ATDC as to be tested in the clinic trials as anti-tumor drugs.

Sunitha Nagrath, Ph.D.

Sunitha Nagrath, PhD.
Assistant Professor, Chemical Engineering

Dr. Nagrath's lab is developing microfluidic devices for isolating and studying cancer cells as related to metastasis.

Metastasis occurs when cells disseminate from the primary tumor site and travel through the body's vasculature, then exit the vessels into distant tissues, adapt to the microenviroment and proliferate into new tumors.

She is using microfluidic devices to study cell migration, specifically how cancer cells enter and exit the vasculature, detecting circulating cancer cells in the blood, and studying the microenvironmental cues needed to sustain and grow tumor metastases.

Microfluidic devices allow for studying individual cell behavior, capturing rare cells, such as circulating tumor cells (CTCs), and sustaining cell cultures. Microfluidics are being created to mimic in vivo environments and will become more widely used in biology as the devices become more automated for general use.

Nouri Neamati, PhD

Nouri Neamati, PhD.
Professor, Department of Medicinal Chemistry

Dr. Neamati's lab uses computational chemistry to match chemical compounds to biological processes in an effort to design novel drugs and therapeutics. Focusing on small-molecule design, Neamati's research aims to find compounds that will fit into active sites in proteins and enzymes to inhibit their expression.

A small-molecule drug works by binding to a target, usually a specialized protein in a disease cell. Before computational chemistry technology was available, researchers had to design or test a compound derived from a natural product, inject it into mice or patients, and then wait to observe the results. This process was slow, expensive and comparatively ineffective. Now, while in vitro testing saves both time and money, sifting through a library of some 10 million compounds still presents a daunting time-consuming drug development process.

Neamati's computational platform allows him to pursue, through a rational selection process that predicts which compounds are likely to inhibit a particular protein, some fifty-thousand compounds to move to the next step in drug discovery. Then, using mathematical and statistical analysis to cluster these compounds into families, Neamati can test one compound from each family under the assumption that they embody properties of other members of the family. Once a compound of interest is identified, he can examine the whole family of compounds to find the optimal match for a specific target.

Another approach to drug design used in the Neamati lab is based on the structure of the target protein. Neamati uses technology that can design a compound that fits nicely on the active site of a protein, like a lock and key. Using the structural knowledge already available on vast numbers of existing drugs and targets, Neamati proceeds by either building a compound based on a known drug or a compound based on the target.

Neamati's work primarily focuses on cancer and HIV. He currently has compounds at various stages of development - from theoretical to in vitro to in vivo. Some of these compounds have been shown to work in experimental mouse disease models while exhibiting no toxicity. Collaborating with colleagues at the TOP, Neamati aims to take these promising therapeutics into phase 1 clinical trials.
